Description

Field of the Invention

[0001] The present invention relates to a crop nutrition and fortification composition, comprising an effective amount of elemental sulfur; one or more magnesium salts or their derivatives or mixtures; one or more potassium fertilizers or their salts or derivatives or mixtures; one or more iron salts or their derivatives or mixtures; one or more zinc salts or their derivatives or mixtures; one or more boron salts or their derivatives or mixtures; at least one trace element selected from vanadium salts or their derivatives or mixtures and selenium salts or their derivatives or mixtures, and at least one excipient, wherein the total content of water-soluble salts or their derivatives or mixtures in the composition does not exceed 80% of the total weight of the composition.

[0002] According to one embodiment, the content of elemental sulfur in the composition ranges from 5% to 90% of the total weight of the composition; the content of elemental magnesium ranges from 0.1% to 40% of the total weight of the composition; the content of elemental potassium ranges from 0.1% to 40% of the total weight of the composition, the content of elemental iron ranges from 0.1% to 45% of the total weight of the composition; the content of elemental zinc ranges from 0.1% to 45% of the total weight of the composition; the content of elemental boron ranges from 0.01% to 15% of the total weight of the composition; the content of elemental selenium ranges from 0.001% to 10% of the total weight of the composition, and the content of elemental vanadium ranges from 0.001% to 10% of the total weight of the composition. Specifically, the crop nutrition and fortification composition comprises microparticles in the size range of 0.1 - 50 microns. More specifically, the crop nutrition and fortification composition is in the form of water-disintegrating granules, water-dispersible granules or a liquid suspension.

[0003] The present invention also relates to a method for preparing a crop nutrition and fortification composition, and a method for treating plants, seeds, crops, plant propagation materials, sites, their parts or soil with the crop nutrition and fortification composition, wherein the composition is in the form of water-disintegrating granules, water-dispersible granules or a liquid suspension.

[0004] The present invention also relates to a method for treating plants and meeting their nutritional requirements, which method enables plants to obtain essential nutrients such as sulfur, potassium, magnesium, micronutrients such as iron, zinc, boron, and micronutrients such as vanadium and selenium, and releases other micronutrients and trace elements in the soil that cannot be utilized by plants due to various factors (mainly soil degradation, antagonism between nutrients, or overuse of nitrogen, phosphorus, potassium or ammonium sulfate fertilizers). In addition, the composition of the present invention reduces the need for over-application of traditional nitrogen, phosphorus, potassium fertilizers and avoids disadvantages such as nitrate leaching and nitrous oxide emissions caused by overuse of nitrogen, phosphorus, potassium fertilizers. Background of the Invention

[0006] In describing the embodiments of the present invention, specific terms have been chosen for clarity. However, the present invention is not limited to the specific terms chosen, and it should be understood that each specific term encompasses all technical equivalents that operate in a similar manner to achieve a similar purpose.

[0007] Nutrition is a key factor in crop growth and development. If plants lack sufficient nutrition, it will lead to poor growth and development, poor physiological development, and be more vulnerable to pests and diseases.

[0008] Macronutrients play an important role in plant growth and development. Micronutrients also play an important role in agriculture. They can help plants relieve environmental stress, improve the nutritional quality of food, promote crop yield increase and improve crop quality. It has been observed that the lack of macronutrients, secondary nutrients, and micronutrients will all lead to a decline in the overall growth and health of crops. In addition, insufficient plant nutrition supply will also lead to poor growth and make plants more vulnerable to pest attacks.

[0009] Potassium (K) is an essential nutrient for plants. It affects a variety of biochemical and physiological processes, and thus affects plant growth and metabolism. Potassium plays a crucial role in enzyme activation, protein synthesis, photosynthesis, osmotic regulation, stomatal movement, energy transfer, phloem transport, cation-anion balance, and stress resistance. Potassium deficiency in crops and plants will lead to chlorosis; wilting and withering of old leaves; leaf deformation and reduction in size; reduction in flowering and branching; reduction in the formation of carbohydrates, proteins, and chlorophyll, and a decline in the quality of fruits and seeds.

[0010] Magnesium (Mg) is an essential element for plant growth and development and plays an important role in plant photosynthesis, cell division, protein formation, and respiration. Due to the mobility of magnesium in plants, magnesium deficiency symptoms first appear in the lower and old leaves and then in the young leaves. Magnesium deficiency symptoms are manifested as yellowing of leaves, with green veins and edges (i.e., interveinal chlorosis). Purple, red, or brown spots may also appear on the leaves. Due to the easy loss of magnesium in the soil and the intensive production of crops, the magnesium content in the soil is also very low. Absolute magnesium deficiency in the soil will significantly reduce the absorption of magnesium by crop roots.

[0011] The role of sulfur as an essential growth nutrient and fertilizer has long been known. Sulfur deficiency has been widespread in most agricultural regions of the world in the past few decades, leading to sulfur being considered a factor limiting crop high yields and fertilizer efficiency. Sulfur is usually applied in the form of elemental sulfur or as a component of certain fertilizers, such as superphosphate, ammonium sulfate, and potassium sulfate. Other reasons for sulfur deficiency include the inability of plants to absorb absorbable sulfur, the loss of sulfur due to leaching and soil pH changes, and the insolubility of elemental sulfur in water.

[0012] Micronutrients are no less important for plant growth than macronutrients. Zinc is a known micronutrient and an important component of various enzymes and proteins; it is involved in the formation of chlorophyll and some carbohydrates, converts starch into sugar, and is present in plant tissues to help plants withstand low temperatures. Zinc is not easily mobile, so zinc deficiency symptoms appear in new leaves, manifested as varying degrees of chlorosis (usually occurring between leaf veins) in new leaves, and necrotic spots may appear at the leaf margins or tips, resulting in smaller leaves that usually curl or twist upward. The formation of carbohydrates, proteins, and chlorophyll in zinc-deficient plants is significantly reduced.

[0013] Iron plays a key role in energy transfer, nitrogen reduction, nitrogen fixation, the process of chlorophyll formation, and the synthesis of a series of enzymes and proteins. Once iron is absorbed into the upper tissues of plants, it is relatively immobile. Therefore, the transport of iron between different parts of plants is restricted, leading to iron deficiency. Iron deficiency usually causes chlorosis (yellowing) and poor nodulation in leguminous crops, resulting in a decrease in plant size and yield.

[0014] Boron (B) is a micronutrient essential for the growth and health of all crops. It is a component of plant cell walls and reproductive structures. Since the requirement for boron is usually small, it is crucial to apply boron as evenly as possible in the field. Traditional boron-containing fertilizer mixtures are difficult to achieve uniform nutrient distribution.

[0015] Trace elements such as selenium are essential for the balanced nutrition of animals and humans. The main source of selenium for animals and humans is diet, which in turn depends on the selenium content in the soil and its bioavailability to crops. Selenium deficiency in humans is associated with various cancers, heart diseases, and other chronic and life-threatening diseases (Gupta et.al, Selenium in soils and crops, its deficiencies in livestock and humans: Implications for management, Communications in Soil Science and Plant Analysis, 31:11 - 14, 1791 - 1807, 2000). Selenium is considered a beneficial element for higher plants, which can enhance the antioxidant metabolism, photosynthesis, secondary metabolite production, and carbohydrate formation in plant leaves. The absorption of selenium by plants is affected by various environmental factors, such as soil pH and the concentration of other competing plant nutrients. In addition, selenium deficiency in plants leads to poor growth and development and leaf chlorosis.

[0016] Vanadium is a trace element that can stimulate the function of antioxidants and help improve the nutritional uptake of phosphorus, iron, copper, zinc, and molybdenum in plants. A deficiency of vanadium in humans can lead to growth retardation, skeletal deformities, and infertility, while a lack of vanadium in plants can affect their growth and yield.

[0017] It is well known that the normal function and growth of plants require optimal nutrient levels. Any change in the nutrient levels can lead to a hindrance in the overall growth of crops and a decline in their health due to deficiency or toxicity, which in turn affects the nutrients essential for the human diet.

[0018] Currently, the existing traditional fertilizers or nutritional compositions on the market either have poor solubility or poor dispersibility, so they cannot be quickly absorbed by plant roots, resulting in nutrient deficiencies. In addition, when large amounts of nutrients such as magnesium are applied at high doses in the soil, it will significantly increase the soil salinity and is easily lost from the soil. Therefore, it is necessary to apply large amounts of nutrients in a suitable form and dose to ensure that they can be absorbed and utilized by plants in a timely manner.

[0019] In addition, modern agriculture faces the challenge of soil degradation, which is caused by the overuse of chemical fertilizers and over-tillage, which in turn leads to a lack of nutrients in crops and harvests, ultimately affecting human nutrition and health. It has been observed that the amount of nitrogen, phosphorus, and potassium fertilizers applied to the soil today is more than twice that of two or three decades ago, but to achieve the same yield. It has been observed that the excessive application of nitrogen fertilizers increases the risk of nitrous oxide emissions.

[0020] In agricultural production, nitrous oxide is emitted into the atmosphere when microorganisms act on the nitrogen that enters the soil through animal urine and feces, synthetic fertilizers, and legumes. The production and use of nitrogen fertilizers both release carbon dioxide, nitrous oxide, and methane, which are the most important greenhouse gases globally. They not only absorb heat and cause climate change but also trigger respiratory diseases due to haze and air pollution. These greenhouse gases can cause extreme weather changes and, by absorbing solar heat, cause global warming and climate change, which is particularly evident in this day and age. It has been observed that the excessive application of nitrogen fertilizers increases the emissions of nitrous oxide. Nitrous oxide poses the greatest risk to climate change; the global warming potential of one pound of nitrous oxide is 300 times that of one pound of carbon dioxide, so it exerts more pressure on temperature changes. Therefore, reducing the use of nitrogen fertilizers and thus reducing nitrous oxide emissions is an urgent priority.

[0021] Further substantial losses of ammonia reduce nitrogen use efficiency, increase the demand for nitrogen fertilizers, and thus exacerbate the risks of nitrous oxide emissions and nitrate leaching. High concentrations of nitrate leaching are toxic and can contaminate drinking water sources with nitrate, a water-soluble nitrogen compound. Excessive intake of nitrate poses a threat to human health. It has been observed that nitrate concentrations in drinking water exceeding 10 mg / L can immediately cause health problems in humans. At extremely high concentrations, nitrate may react with amides and amines to form carcinogenic compounds such as nitrosamines and nitrosamides.

[0022] In addition, when excessive nitrate is not absorbed by plants, it will be lost from the plant root zone, leaving hydrogen ions, thus increasing soil acidity, which in turn causes plants to be unable to absorb nutrients from acidic soils.

[0023] Due to the large application of nitrogen, phosphorus, and potassium compound fertilizers, potassium accumulates in the soil, which will have an antagonistic effect on the absorption of other nutrients (such as magnesium and calcium), that is, it inhibits the absorption of magnesium or calcium by plants, resulting in plant deficiency of these nutrients.

[0024] In addition, with the increase in the application rate of ammonium sulfate, the magnesium deficiency in plants becomes increasingly serious. The direct adverse effect of ammonium sulfate on plant magnesium supply is considered to be due to the competitive effect of NH4+ and H- ions on magnesium absorption. These ions are produced in large amounts in root tissues shortly after NH4+ ion absorption. (Nitrogen-Magnesium Relationships in CropPlants by E.G.Mulder*,Agricultural Experiment Station and Institute for SoilResearch T.N.O.,Groningen,The Netherlands).

[0025] Therefore, proper crop nutrition is crucial for optimizing crop growth, development, and metabolism, which in turn helps to improve crop yield and product quality.

[0026] Further observations have found that crop nutrition management is very difficult due to factors such as soil carbonate content, soil salinity, soil moisture, soil alkalinity, and low temperature.

[0027] When multiple macronutrients and secondary or micronutrient elements are present simultaneously, how to address the problem of nutrient antagonism is also a major challenge. Sometimes, the interactions between plant nutrients may exhibit antagonistic or synergistic effects, thus affecting nutrient use efficiency. Sometimes, "nutrient antagonism" is observed in plants, i.e., excessive application of one element can hinder the absorption of another required element by the plant, resulting in nutrient deficiency in the plant. Nutrient-imbalanced soils are prone to nutrient antagonism and require unconventional solutions to increase yields. When applied to the soil or foliarly sprayed, the nutrients in the fertilizer components compete with each other. Therefore, both nutrient antagonism in the soil and in the inputs or fertilizers are major challenges, and both challenges must be addressed simultaneously when striving to provide balanced nutrition for crops.

[0028] Some of the most common antagonisms include iron antagonizing zinc or manganese (or vice versa), zinc antagonizing copper, magnesium antagonizing calcium (or vice versa), and potassium antagonizing magnesium and calcium.

[0029] It is well known that unilateral over-supply of potassium inhibits the absorption of magnesium, resulting in potassium-magnesium antagonism. There is an antagonistic interaction / competition between potassium and magnesium, as reported (K.L. Kabu et.al, Influence of potassium-magnesium antagonism on tomato Plant growth, Can.J.Plant Sci. 50:711-715 (Nov. 1970)). Soils treated with high-potassium fertilizers reduce the utilization rate of magnesium by plants and may cause magnesium deficiency in crops growing in soils with low magnesium content. Conversely, crops growing in high-magnesium soils may be potassium-deficient, especially in soils with high phosphorus and low potassium content.

[0030] Therefore, given the antagonism between magnesium and potassium, zinc and iron, or zinc and copper, developing an agricultural fertilizer is always a challenge. Such a fertilizer should not only overcome this problem and increase the absorption of all nutrients, but also maintain the soil pH value simultaneously and successfully meet the plant's requirements for potassium, magnesium, and other micronutrient elements, ultimately affecting human nutrition.

[0031] Another reason for plant nutrient deficiency is "complexation", i.e., elements mix and combine to form an insoluble compound that cannot be absorbed by plant roots. Therefore, the most limiting nutrients must be applied in balance to achieve the highest yields while minimizing nutrient losses.

[0032] Therefore, proper crop nutrition is crucial for optimizing crop growth and metabolism, which in turn helps to increase crop yields and product quality. Adequate crop nutrition is also essential while reducing the application of nitrogen, phosphorus, potassium, or ammonium fertilizers to avoid the drawbacks associated with nitrous oxide emissions and nitrate leaching in the soil.

[0033] In addition, agricultural-related problems include environmental conditions such as drought, biotic and abiotic stresses, poor soil conditions or soil nutrient depletion, resulting in a decrease in the yield and quality of agricultural products.

[0034] Suitable compositions containing macronutrients such as potassium, sulfur and magnesium, as well as other micronutrients such as iron, zinc, boron, and other micronutrients such as selenium or vanadium are unknown.

[0035] Therefore, it is a challenge and thus worthy of expectation to provide sufficient and balanced nutrition in the form of a combination of macronutrients and micronutrients, enabling plants to absorb nutrients to the maximum extent while solving the problem of nutrient antagonism.

[0036] Another object of the present invention is to develop a crop nutrition and fortification composition that can avoid the overuse of synthetic NPK fertilizers or ammonium sulfate-based fertilizers, not only prevent soil degradation, reduce nitrous oxide emissions, avoid nitrate leaching, improve soil health and pH value, but also increase the yield and quality of agricultural products while reducing the application rate of the composition.

[0037] Common traditional fertilizers or nutritional compositions on the market currently either have poor solubility or poor dispersibility, so they cannot be quickly absorbed by plant roots, resulting in nutrient deficiencies. In addition, high-concentration water-soluble fertilizers are easily leached from the soil during application, thereby reducing the utilization rate of fertilizers by crops or plants.

[0038] Traditionally, known forms of micronutrient compositions in the art include bentonite granules or tablets, pellets / granules, granules prepared by the melting method, etc. Such micronutrient composition products in the form of granules, pellets or tablets contain swelling clay and have some disadvantages. These compositions are usually large in size and contain swelling clay, which swells when in contact with moisture and decomposes into large microparticles of uneven size. Such granules or tablets also cause irregular release of micronutrients, unable to meet the nutritional requirements of plants, and ultimately resulting in poor field efficacy.

[0039] In addition, patent application number US20170283334A1 discloses a micronutrient composition that contains a combination of water-insoluble and water-soluble micronutrients in a hydrated polyelectrolyte solution. The polyelectrolytes in this composition undergo physical cross-linking to form a viscous gel-like matrix in which solid micronutrients are dispersed. Such compositions are intended to achieve rapid release and slow release of active ingredients with the aid of polyelectrolytes and metal complexing agents. However, these high-concentration formulations are difficult to dilute in water, cannot form a stable dispersion, and are prone to forming hard packages, so they are not suitable for practical applications. Such viscous, large-particle-size formulations are difficult to pour and easily clog the nozzles, thus affecting the delivery of nutrients to plants or crops.

[0040] The present inventors unexpectedly found that the crop nutrition and fortification composition comprises: an effective amount of elemental sulfur; an effective amount of one or more water-insoluble or water-soluble magnesium salts or their derivatives or mixtures; one or more water-insoluble or water-soluble potassium fertilizers or their salts or derivatives or mixtures; one or more water-insoluble or water-soluble iron salts or their derivatives or mixtures; one or more water-insoluble or water-soluble zinc salts or their derivatives or mixtures; one or more water-insoluble or water-soluble boron salts or their derivatives or mixtures; at least one trace element selected from water-insoluble or water-soluble vanadium salts or their derivatives or mixtures and water-insoluble or water-soluble selenium salts or their derivatives or mixtures; and at least one excipient in a concentration range of 0.1% to 40%, wherein the composition comprises fine particles with a size range of 0.1 micrometers to 50 micrometers, and wherein the total content of water-soluble salts or derivatives or mixtures in the composition does not exceed 80% of the total weight of the composition. In another embodiment, the content of elemental sulfur in the composition is in the range of 5% to 90% of the total weight of the composition; the content of elemental magnesium is in the range of 0.1% to 40% of the total weight of the composition; the content of elemental potassium is in the range of 0.1% to 40% of the total weight of the composition, the content of elemental iron is in the range of 0.1% to 45% of the total weight of the composition; the content of elemental zinc is in the range of 0.1% to 45% of the total weight of the composition, the content of elemental boron is in the range of 0.01% to 15% of the total weight of the composition; the content of elemental selenium is in the range of 0.001% to 10% of the total weight of the composition, and the content of elemental vanadium is in the range of 0.001% to 10% of the total weight of the composition; showing excellent field efficacy.

[0041] The inventors noted that a crop nutrition and fortification composition containing a specific ratio of various nutrient combinations, when formulated according to the embodiments of the present invention and containing fine particles with a specific particle size distribution, also unexpectedly addresses the challenge of nutrient antagonism in the soil, such as the antagonism between zinc and iron or magnesium and potassium. In addition, applying the composition of the present invention surprisingly enables better absorption of all nutrients, reduces the need for excessive application of traditional NPK fertilizers, and avoids drawbacks such as nitrous oxide emissions and nitrate leaching caused by excessive use of NPK fertilizers. The composition of the present invention enables more balanced absorption of all nutrients, thereby making the plant or crop healthier and increasing the total crop yield and product quality. It was particularly observed that the crop nutrition and fortification composition of the present invention not only avoids the excessive use of high-dose NPK fertilizers, but also meets the needs of the crop by providing a multi-nutrient solution, improving the absorption of macronutrients such as potassium, magnesium and sulfur as well as other micronutrients retained in the soil at a reduced application rate, while also improving soil health.

[0042] In addition, the inventors of the present application have determined that crop nutrition and fortification compositions in the form of water-dispersible granules, liquid suspensions, or water-disintegrating granules contribute to increasing plant yields, improving soil health, maintaining soil pH, and balancing the uptake of all nutrients by crops or plants, reducing leaf yellowing, and exhibiting improved plant physiological parameters such as increased rooting, improved leaves, disease resistance, and increased crop greenness, thereby providing nutritionally rich and fortified crops.

[0043] The compositions in the form of water-dispersible granules or liquid suspensions of the present invention also exhibit excellent physical properties such as suspensibility, dispersibility, fluidity, and wettability. Therefore, compared with using the active ingredient alone or commercial products, even when applied at a reduced application dose, the compositions still exhibit excellent field efficacy. Summary of the Invention

Then, under the condition of continuous homogenization, 1.1 parts of xanthan gum, 1 part of 1,2-benzisothiazolin-3-one, the balance of water and 0.3 part of polydimethylsiloxane emulsion were added to obtain a liquid suspension.

[0406] Results: The particle size of the composition was d10: 4.90 μm, d50: 6.5 μm, d90: 15.75 μm, the viscosity was 480 cps, and the suspension property was 85%. The pourability rinse residue was 0.65%, the spontaneous dispersibility was 85%, and the 75-μm wet sieve retention value was 0.05%.

[0407] B. Field study:

[0408] Experiment 1: To study the effects of a composition containing sulfur, potassium, magnesium, zinc, iron, boron, vanadium and selenium on commercially cultivated tomato crops, wherein the composition is a water-disintegrating granule, a water-dispersible granule and a liquid suspension, and its particle size conforms to the present invention, and the comparative sample is in the form of a pill with a larger particle size.

[0409] The experiment was carried out in Baroda, Gujarat during the Kharif season, using a randomized block design (RBD), with a total of 11 treatment groups (including an untreated control), repeated 4 times. The plot area of each treatment group was 40 square meters (8 m x 5 m). The evaluated components included sulfur, potassium, magnesium, zinc, iron, boron, vanadium and selenium, with different concentrations according to the present invention, and a comparative sample was attached. The tomato crops in the experimental field were planted according to good agricultural practices. The tomato seeds of variety GT-3 were used in this study, with a planting spacing of 120 cm and a plant spacing of 45 cm. The details of the experiment are as follows:

[0421] k) Harvest dates: October 5, 2022, October 13, 2022, November 20, 2022

[0422] The way to observe the results is to mark the newly opened flowers once a week and count the number of marked flowers that bear fruit after one week. The fruits are harvested three times and weighed each time.

[0423] The observation results are recorded in the following table:

[0429]

[0430]

[0431] As can be seen from Table 1 above, compared with T2, T4, T6, T8, and T10 using a conventional particulate form of the composition containing expanded clay with a particle size above 75 microns, the compositions T1, T3, T5, T7, and T9 in the form of water-dispersible granules, water-disintegrating granules, or liquid suspensions (whose particle sizes are according to the embodiments of the present invention) show a significant increase in tomato yield. It can be seen that compared with the untreated control group, the treatment groups T1, T3, T5, T7, and T9 applying the composition of the present invention have an increase in tomato yield of 22.98%, 22.45%, 21.47%, 22.04%, and 19.05% respectively, while the treatment groups T2, T4, T6, T8, and T10 have an increase in yield of only 7.43%, 6.32%, 7.57%, 6.59%, and 7.18% respectively compared with the untreated control group.

[0432] Table 1A: (Continued Table 1)

[0433]

[0434]

[0435]

[0436]

[0437] As can be seen from Table 1A above, compared with treatments T2, T4, T6, T8, and T10 using conventional pill compositions with a larger size range, the tomato plant height and the number of fruits per plant in treatment groups T1, T3, T5, T7, and T9 using the water-disintegrating granule composition, water-dispersible granule composition, and liquid suspension composition with the particle size of the embodiments of the present invention are significantly increased. The plant heights of treatment groups T1, T3, T5, T7, and T9 using the composition of the present invention are increased by 23.54%, 18.97%, 22.0%, 22.99%, and 18.69% respectively compared with the untreated control group, while the plant heights of treatment groups T2, T4, T6, T8, and T10 are only increased by 8.58%, 6.92%, 8.17%, 6.5%, and 5.95% respectively compared with the untreated control group. In addition, compared with the untreated control group, the number of fruits per plant in treatment groups T1, T3, T5, T7, and T9 applying the composition of the present invention is significantly increased, while the increase in the number of fruits per plant in treatment groups T2, T4, T6, T8, and T10 compared with the untreated control group is not much.

[0438] In addition, the crop leaves treated with the composition of the embodiments of the present invention are denser and greener, and the root systems are also improved.

[0439] The surprising results observed in Table 2 and Table 2A, that is, the results of treatment with the composition of the present invention, can be attributed to all elements, namely sulfur, potassium, magnesium, zinc, iron, boron, vanadium, and selenium, existing in specific concentrations and formulations, and the particle size conforming to the embodiments of the present invention. On the other hand, the dispersibility and suspension of the traditional granule compositions used in treatment groups T2, T4, T6, T8, and T10 are very poor, so the absorption and utilization rate of plants are reduced, which in turn leads to a reduction in the efficacy of these compositions.

[0440] Experiment 2: To study the effect of the "sulfur, potassium, magnesium, zinc, iron, boron, vanadium, and selenium" composition on commercially grown rice crops, wherein the composition is in the form of a suspension concentrate, the particle size range is according to the embodiments of the present invention, and it is applied in combination with different doses of RDF (120 - 60 - 60 N - P2O5 - K2O / ha) and the composition containing only RDF, in rice:

[0441] Field test method:

[0442] A field test was carried out in Gandhinagar, Gujarat to evaluate the effect of the composition of the present invention on rice yield. The test was conducted during the Kharif season, using a randomized block design (RBD). A total of 11 treatment groups were set up, including an untreated control, with 4 replications. The plot area of each treatment group was 40 square meters (8 meters x 5 meters). 15 days after rice transplanting, the specified dose of the test product was applied as top dressing. The rice crops in the test field were planted according to good agricultural practice. Seeds of the rice variety CSR-30 were used for seedling raising, and 25-day-old seedlings were transplanted into the test field with a row spacing of 30 cm and a plant spacing of 25 cm. The effective doses applied in the field test were elemental sulfur, elemental potassium, elemental magnesium, elemental zinc, elemental iron, elemental boron, elemental selenium, and elemental vanadium.

[0455] Yield observations were recorded at harvest, and the average data are listed in Table 1 to illustrate the efficacy of the composition containing sulfur, potassium, magnesium, zinc, iron, boron, selenium, and vanadium prepared according to the examples of the present invention.

[0460]

[0461]

[0462]

[0463] As can be seen from the data in Table 2 above, Treatment Group T1 used the liquid suspension composition of the embodiment of the present invention (containing 25% of RDF 120 - 60 - 60 N - P2O5 - K2O). Treatment Groups T2 and T3 respectively used the composition of the embodiment of the present invention and combined 50% of RDF (120 - 60 - 60 N - P2O5 - K2O) and 100% of RDF (120 - 60 - 60 N - P2O5 - K2O), and applied them in different doses. Treatment Groups T4, T5 and T6 used penta - effective compositions of different concentrations of sulfur, zinc, iron, potassium and magnesium. Among them, Treatment Group T4 contained 25% of RDF, Treatment Group T5 contained 50% of RDF and the penta - element composition, and Treatment Group T6 contained 100% of RDF and the penta - element composition. Treatment Groups T7, T8 and T9 were carried out using ternary compositions of different concentrations of sulfur, potassium and magnesium. Among them, Treatment Group T7 contained 25% of RDF, Treatment Group T8 contained 50% of RDF and the penta - element composition, and Treatment Group T9 contained 100% of RDF and the penta - element composition. Treatment Group T10 applied RDF alone. As can be seen from the data provided in the above table, compared with the treatment of applying RDF alone (Treatment 10), Treatment Group T1 using the composition according to the embodiment of the present invention at a formulation dose of 32 kg / acre showed a better increase in yield. Compared with Treatment Group T4 using the penta - element active ingredient composition or Treatment Group T7 using the ternary active ingredient composition, the composition according to the present invention showed a significant increase in yield.

[0464] Table 2A (continued from Table 2)

[0465]

[0466]

[0467]

[0468] As can be seen from Table 2A above, compared with the compositions of Treatments T2, T3 and T10, the composition according to the embodiment of the present invention led to a significant reduction in N2O and CO2 emissions, thereby making the composition of the present invention environmentally friendly and eliminating the hazards associated with nitrous oxide emissions.

[0469] It should be noted that the treatment group 1 of the specific embodiments of the present invention and the application of 25% RDF (traditional NPK fertilizer) have higher yields than the treatment group T2 applying 50% RDF and also higher than the treatment group T10 applying RDF alone. At the same time, the greenhouse gas emissions are also significantly reduced. For example, compared with the treatment group T10 applying only RDF, the treatment group T1 of the specific embodiments of the present invention has an astonishing 80.75% reduction in CO2 emissions and a 69.5% reduction in N2O emissions. Compared with the treatment groups T2 and T3 applying 50% RDF and 100% RDF respectively and the specific embodiments of the present invention, the compositions of the specific embodiments of the present invention also significantly reduce greenhouse gas emissions.

[0470] In addition, compared with the treatment group T4 applying a five - element composition of sulfur, potassium, magnesium, iron and zinc and the treatment group T7 applying a three - element composition of sulfur, potassium and magnesium, the treatment group T1 applying the composition of the present invention shows a significant increase in yield.

[0471] Experiment 3: In order to evaluate the composition of the present invention containing "sulfur, potassium, magnesium, zinc, iron, boron, vanadium and selenium", wherein the composition includes fine particles with a size range of 0.1 micrometer to 50 micrometers and is compared with a control sample in the form of a water - disintegrating granule in soybeans, wherein each control sample includes any one of a water - soluble zinc salt, a water - soluble iron salt and a water - soluble magnesium salt:

[0472] Field test method:

[0473] In the soybean field test in Junagadh, Gujarat, the effects of the water - soluble granules containing sulfur, potassium, magnesium, zinc and iron of the present invention and their control samples were observed. The test was carried out in the Kharif season, using a randomized block design (RBD), with a total of 7 treatment groups (including an untreated control group) and repeated 4 times. The plot area of each treatment group was 30 square meters (6 meters x 5 meters). The water - soluble granule compositions (test product compounds) with different concentration ranges of the present invention and the control compositions were applied to the soil at the time of sowing according to the specified dosages. The soybean crops in the test fields were planted according to good agricultural practices.

[0474] Test details:

[0475] a) Test location: Junagadh, Maharashtra

[0476] b) Crop and variety: Soybean - 3 (GJS - 3)

[0477] c) Test season: Kharif season 2023

[0478] d) Test design: Randomized block design

[0479] e) Number of repetitions: 4

[0480] f) Number of treatment groups: 7

[0481] g) Plot area: 6 m x 5 m = 30 square meters

[0482] h) Sowing date: July 18, 2023

[0483] i) Application date: July 18, 2023

[0484] j) Application method: Soil application

[0485] k) Harvest date: October 20, 2023

[0486] Observation results are recorded in the following table:

[0487] Table 3:

[0488]

[0489]

[0490]

[0491]

[0492] As can be seen from the data in Table 1, for treatment group T1 which applied the suspension concentrate (with particle size in the range of 0.1 to 30 microns) of the embodiment of the present invention, the soybean yield increased significantly by 31.28% compared to the untreated control group. In contrast, for treatment group T2 which applied a water-dispersible granule containing sulfur, magnesium, potassium, zinc and iron (without boron, vanadium, selenium or copper), and treatment group T3 which applied a water-dispersible granule containing sulfur, magnesium and zinc (with particle size in the range of 0.1 to 50 microns), it can be seen that the yields of treatment group T2 and treatment group T3 increased by 13.87% and 6.43% respectively compared to the untreated control. Another treatment group T4 of the composition in the form of a suspension concentrate according to the embodiment of the present invention had a yield increase of 28.07% compared to the untreated control group, while treatment group T5 which applied a composition containing sulfur, potassium, iron, zinc and boron and treatment group T6 which applied a composition containing only sulfur, zinc and boron had yield increases of 12.86% and 4.97% respectively compared to the untreated control group.

[0493] Table 3A (continued from Table 3)

[0494]

[0495]

[0496]

[0497] The soil nutrient content before sowing and application treatments was estimated, and the initial soil nutrient content of the treated and observed plots was noted to be 1010 ppm for nitrogen, 1156 ppm for zinc, 1230 ppm for iron, 1227 ppm for potassium, 960 ppm for boron, 946 ppm for selenium, 925 ppm for vanadium, and 965 ppm for copper.

[0498] As can be seen from the data in Table 3A above, after applying the compositions of the examples of the present invention and the comparative samples, compared with the treatment groups T2, T3, T5, and T6 that applied the comparative samples, the treatment groups T1 and T4 that applied the compositions of the examples of the present invention significantly increased the absorption of magnesium, zinc, iron, boron, potassium, selenium, vanadium, and copper in the soil. In addition, it can be seen that the composition of the present invention with an optimized particle size distribution not only enhanced the absorption of nutrient elements such as magnesium, zinc, iron, boron, potassium, selenium, and vanadium, but also solved the problem of nutrient antagonism. As mentioned above, the presence of iron is known to inhibit the absorption of zinc or manganese in the soil. Similarly, the presence of zinc in the composition reduces the absorption of copper. As can be seen from the treatment groups T2, T3, T5, and T6 in the above table, due to the presence of iron in the composition, the absorption of zinc is significantly poorer, and the absorption of copper is reduced due to the presence of zinc. On the other hand, it is worth noting that the treatment groups T1 and T3 using the compositions of the examples of the present invention showed a surprising enhancement in the absorption of nutrient elements such as sulfur, magnesium, potassium, zinc, iron, boron, manganese, and copper in the soil, thus overcoming the problem of nutrient antagonism and promoting the balanced absorption of nutrient elements by plants.

[0499] Experiment 4: Evaluate the efficacy of different formulations of D sulfur, potassium, magnesium, zinc, iron, boron, vanadium, and selenium (octa-component composition) and comparative samples containing hepta-component active ingredient composition, hexa-component active ingredient composition, penta-component active ingredient composition, and tri-component active ingredient composition in commercially cultivated wheat crops:

[0500] Field test method:

[0501] Field trials were conducted in wheat fields in Satara, Maharashtra to observe the yield-increasing effect of the liquid suspension composition of the octa-component active ingredient composition (sulfur, potassium, magnesium, iron, zinc, boron, vanadium, and selenium) of the present invention on wheat. The trials compared the liquid suspension compositions of the hepta-component active ingredient composition (sulfur, potassium, magnesium, iron, boron, vanadium, and selenium), the hexa-component active ingredient composition (sulfur, potassium, magnesium, iron, boron, and selenium), the penta-component active ingredient composition (sulfur, magnesium, iron, zinc, and selenium), and the tri-component active ingredient composition (sulfur, magnesium, and iron). The trials were conducted using a randomized block design (RBD) during the rabi season, with a total of six treatment groups (including an untreated control), replicated four times. The plot area for each treatment group was 30 square meters (6 meters x 5 meters). The test product compound provided by the present invention (in the form of a liquid suspension composition) and the control samples at different concentration ranges and specified doses were applied to the soil during the first irrigation of wheat (25 days after sowing). The wheat crops in the experimental fields were planted according to good agricultural practices.

[0514] Table 4:

[0515]

[0516]

[0517] As can be seen from Table 4 above, compared with treatment groups T2, T3, T4, and T5 using liquid suspension compositions, where treatment group T2 does not contain zinc, treatment group T3 does not contain zinc and vanadium, treatment group T4 does not contain potassium, boron, and selenium, and treatment group T5 contains only sulfur, potassium, and magnesium, the wheat yield of treatment group T1, which was applied with a liquid suspension composition containing sulfur, magnesium, potassium, zinc, iron, boron, vanadium, and selenium (with particle size according to the embodiments of the present invention), was significantly increased by 33.03% compared to the untreated control group. The yield increases of treatment groups T2 and T3 were only 21.33% and 20.03% respectively. For treatment group T4 using a five - element composition of sulfur, zinc, iron, magnesium, and vanadium, the yield increase was 18.07%, while for treatment group T5 using a three - element composition of sulfur, magnesium, and zinc, the yield only increased by 8.95% compared to the untreated control group.

[0518] The surprising results observed in treatment group T1 using the composition of the present invention in the above table can be attributed to the presence of all elements, namely sulfur, potassium, magnesium, zinc, boron, iron, vanadium, and selenium at specific concentrations and formulations, with particle size according to the embodiments of the present invention, and the absence of any one element will lead to a significant decrease in wheat yield and other crop characteristics.

[0519] Experiment 5:

[0520] To study the effects of different "sulfur, potassium, magnesium, zinc, iron, boron, vanadium, and selenium" compositions on commercially grown peanut crops, these compositions exist in the form of water - soluble granules and suspensions in the embodiments of the present invention and are compared with comparative samples. Among them, the active ingredient content in the granules of the present invention is 80%, and the active ingredient content in the comparative sample exceeds 80%.

[0521] In Jalgaon, Maharashtra, a field experiment was conducted on peanut crops (variety JL - 220) to evaluate the effects of the compositions of the present invention. The experiment used a randomized block design (RBD), with three treatment groups (including an untreated control), repeated four times. The plot area of each treatment group was 35 square meters (7 meters x 5 meters). The test nutrient compositions in the embodiments of the present invention (in the form of water - dispersible granules or suspensions in different concentration ranges) and the specified dose of the control sample were applied as basal fertilizers at the time of peanut crop sowing.

[0522] The experiment details are as follows:

[0523] a) Test location: Jalgaon, Maharashtra

[0524] b) Crop: Peanut (variety JL - 220)

[0525] c) Test season: Kharif season 2023

[0534] Table 5:

[0535]

[0536]

[0537] As can be seen from Table 5 above, compared with the treatment group T2 of the water-soluble granule composition with the water-soluble active ingredient content accounting for 85% of the total weight of the composition, the treatment group T1 of the water-dispersible granule composition with the water-soluble active ingredient content not exceeding 80 wt.% of the present invention's embodiment has a significantly increased peanut yield. At the same time, it was also observed that the composition of the treatment group T2 with the water-soluble salt content exceeding 85 wt.% becomes hygroscopic and loses stability and applicability due to deterioration after long-term storage.

[0538] Table 5A (continued from Table 5)

[0539]

[0540]

[0541] It can also be seen from Table 5A above that for the treatment group T1 applying the water-soluble granule composition with the water-soluble active ingredient content not exceeding 80 wt.% of the present invention's embodiment, compared with the treatment group T2 applying the water-soluble granule composition with the water-soluble active ingredient content of 85 wt.%, the average number of pods per plant and the protein content of peanut seeds are both significantly increased.

[0542] For the treatment group T1 applying the composition of the present invention, the number of peanut pods per plant increased by 22.67% compared with the untreated control group, while the number of peanut pods in the treatment group T2 only increased by 14.97%. In addition, it can be seen that the protein content of peanut seeds in the treatment group T1 increased by 24.19%, while the protein content of peanut seeds in the treatment group T2 only increased by 14.97% compared with the untreated control group.

[0543] The surprising results observed in Tables 5 and 5A (treatment groups administered with the compositions of the present invention) can be attributed to the concentration range of the active water-soluble salts present in the water-dispersible granule compositions not exceeding 80 wt.%.

[0544] Experiment 6: To evaluate the efficacy of different formulations containing sulfur, potassium, magnesium, zinc, iron, boron, selenium, and vanadium, wherein the compositions have a particle size according to an embodiment of the present invention, as compared to compositions having a higher particle size range in rice:

[0545] Field test method:

[0546] The experiment was conducted using a randomized block design (RBD) during the Kharif season, with a total of five treatment groups, including an untreated control, and replicated four times. The rice crops in the test fields were planted using good agricultural practices.

[0560] Table 6:

[0561]

[0562]

[0563]

[0564]

[0565] As can be seen from Table 6 above, compared with treatment groups T2, T4, and T6 that applied particulate compositions with a larger particle size range, the treatment groups T1, T3, and T5 that applied the water-soluble particulate composition with the particulate size of the embodiments of the present invention had a significantly increased rice yield. The rice yields of treatment groups T1, T3, and T5 that applied the composition of the present invention were increased by 22.67%, 25.23%, and 21.77% respectively compared with the untreated control group, while the rice yields of treatment groups T2, T4, and T6 that applied particulate compositions with a larger particle size range were only increased by 6.80%, 7.75%, and 7.27% respectively compared with the untreated control group.

[0566] In addition, the crops treated with the composition of the embodiments of the present invention had denser and greener leaves.

[0567] Table 6A: Continued Table 6

[0568]

[0569]

[0570]

[0571] The soil nutrient content before sowing and application treatment was estimated, and it was noted that the initial sulfur content of the plots in the treatment groups and the observation group was 2632 ppm, the magnesium content was 1480 ppm, the zinc content was 1890 ppm, the iron content was 1682 ppm, the potassium content was 1450 ppm, the boron content was 1308 ppm, the vanadium content was 1065 ppm, and the selenium content was 987 ppm.

[0572] As can be seen from the data in Table 6A above, after applying the compositions of the embodiments of the present invention and the control samples, compared with the treatment groups T2, T4, and T6 using water-disintegrating granules with larger particle sizes, the treatment groups T1, T3, and T5 applying the compositions of the embodiments of the present invention (the components of which include potassium, magnesium, iron, zinc, vanadium, and selenium) significantly increased the absorption of zinc, iron, magnesium, potassium, boron, vanadium, and selenium in the soil. In addition, it can be seen that the compositions of the present invention not only enhanced the absorption of nutrients in the soil but also solved the problem of nutrient antagonism. As described above, the presence of iron is known to inhibit the absorption of zinc in the soil, and the presence of magnesium is known to inhibit the absorption of potassium in the soil, and vice versa. As can be seen from Treatments 2, 4, and 6 in the above table, due to the antagonistic effect of these active ingredients in a single composition, the absorption of zinc or iron is significantly poor. In addition, as can be seen from treatment groups T2, T4, and T6, when magnesium is present in the composition, the absorption of potassium is significantly poor, and vice versa. On the other hand, it is worth noting that treatment groups T1, T3, and T5 using the compositions based on the embodiments of the present invention showed a surprising enhancement in the absorption of nutrients such as sulfur, magnesium, zinc, iron, and potassium present in the soil, thus solving the problem of nutrient antagonism.

[0573] Experiment 7: Study the effect of the "sulfur, potassium, magnesium, zinc, iron, boron, vanadium, and selenium" composition in commercially cultivated maize, wherein the composition is a water-dispersible granule, and the particle size range is in accordance with the embodiments of the present invention, combined with different doses of RDF (120 - 60 - 60 N - P2O5 - K2O / ha) in maize:
