Abstract
Description
A SOLUBILIZING COMPOSITION FIELD OF DISCLOSURE
[0001] This disclosure relates to a solubilizing composition. The solubilizing composition of this disclosure facilitates the solubilization of fertilizer compounds and / or fertilizer compositions. In particular, this disclosure relates to a solubilizing composition comprising a first anionic surfactant and at least one first wetting agent. Preferably, the solubilizing composition also includes at least one second wetting agent. The first wetting agent is typically a polyol wetting agent, and the second wetting agent is typically an alkyl(poly)glucoside. The solubilizing composition may also include a solvent such as water. The disclosure extends to a method of solubilizing fertilizer compounds and / or fertilizer compositions, particularly fertilizer compounds and / or fertilizer compositions containing potassium (K) and / or phosphorus (P). BACKGROUND TO THE DISCLOSURE
[0002] Many fertilizers containing phosphorus (P) and potassium (K) are known. It is generally desirable to solubilize fertilizers in a tank mix before irrigating and / or fertigating crops.
[0003] Phosphorus (P), usually in the form of phosphates, and fertilizers containing potassium (K) are known to have low solubility when tank-mixed before dispersion in an agricultural application by irrigation or fertigation. This low solubility applies to both concentrated and dilute tank mixes, but is most common in concentrated tank mixes. It is not uncommon for certain fertilizer compounds to precipitate out of solution and / or form a gel, which can impair the dispersion of tank-mixed fertilizers in use by clogging irrigation cross-linking systems. It is desirable to solubilize fertilizer compounds and / or fertilizer compositions to provide a stable, solubilized tank mix.In agricultural applications, it is desirable to concentrate liquid fertilizers containing phosphorus (P) and potassium (K) in application tanks on seed drills to reduce the need for refilling during planting and to reduce the weight of the aqueous diluent in the vehicle, thus minimizing compaction. The P and K are then applied in highly concentrated forms, but due to the lack of dilution, they cannot be dispersed in the soil. A farmer then relies on irrigation, rain, or snowmelt to disperse the liquid fertilizers containing phosphorus (P) and potassium (K) into the soil. This creates uncertainty and is inefficient.
[0004] In addition, surfactants are often desired for a plethora of well-established reasons. Surfactants are typically employed in agriculture to reduce the surface tension of water by reducing hydrogen bonds, which in turn facilitates the dispersion of water over the soil and through the soil pores.
[0005] Anionic surfactants are readily available and effective for wetting dry soil that has become hydrophobic over time. Soil often becomes hydrophobic during periods of reduced rainfall. These anionic surfactants typically function effectively as soil wetting agents due to their negatively charged component.
[0006] However, it is well established that anionic surfactants cause certain fertilizer compounds, for example, fertilizers containing potassium (K) and phosphorus (P) (particularly when concentrated), to precipitate out of solution and / or form a gel, making it difficult to mix the anionic surfactants with the concentrated liquid fertilizer. This necessitates additional spray applications that use more water, time, and equipment, and increases compaction. Although significant dilution of anionic surfactants can hinder the precipitation of fertilizer compounds, this requires excess water and therefore multiple application rounds and increased soil compaction, which is undesirable.Anionic surfactants should not be mixed with solutions of P and / or K fertilizer concentrates, as precipitation of fertilizer compounds that clog crosslinking and / or fertigation systems is common.
[0007] A known way to improve fertilizer solubility is by using certain nonionic surfactants as a substitute for anionic surfactants, although some nonionic surfactants also exhibit incompatibility with fertilizers (for example, the ethoxylated alcohol surfactant often causes a saline effect when mixed with fertilizers due to the binding of cations with ethylene oxide ether oxygen and dehydration of the nonionic surfactant). Advances in nonionic surfactants include the use of block copolymers such as ethylene oxide-propylene oxide (EO / PO) block copolymers. While they often improve the precipitation problem, nonionic surfactants are expensive and not as effective at wetting hydrophobic soils compared to anionic surfactants, particularly after drought or a prolonged dry season.The need remains to supply phosphorus (P) and / or potassium (K) fertilizers in concentrated tank mixes (to avoid unnecessary soil compaction and / or reduce water use), and the need to provide anionic surfactants for crops, seeds, or soil in agricultural enterprises persists. There remains a need to provide a new and innovative solubilizing composition that at least improves upon one of the known disadvantages of the prior art or the method described above. qp LQnn / cznz / q / uιλι BRIEF DESCRIPTION OF THE INVENTION

[0059] The content of the Abstract is repeated here for reference to avoid repetition. Generally, in a preferred embodiment, a solubilizing composition is provided comprising an anionic surfactant and two wetting agents (a first wetting agent and a second wetting agent), wherein the solubilizing composition is stable. In use, the solubilizing composition solubilizes aqueous fertilizer compounds and / or liquids and / or fertilizer compositions, each of which contains at least phosphorus (P) and / or potassium (K). In a particular embodiment of the disclosure, the solubilizing composition also includes a pH adjustment medium and / or a solvent and / or a nonionic surfactant and / or additives.The subject of this disclosure is particularly useful and / or advantageous for in-furrow applications, as it prevents gelation and / or coagulation that would otherwise block irrigation / fertigation systems and / or cause fertilizers to precipitate in the tank, preventing them from reaching their intended target in the field. The solubilizing composition of this disclosure prevents coagulation in a tank mix, particularly when added to concentrated P and K fertilizers (which have a low or non-aqueous content).
[0060] As described in this document, it is well established that anionic surfactants cause certain fertilizer compounds, for example, fertilizers containing potassium (K) and phosphorus (P), to precipitate out of solution and / or form a gel, making it very difficult to mix more common anionic or non-ionic surfactants with the fertilizer. This is particularly problematic when the fertilizer is in concentrated form.
[0061] The functionality of surfactants and / or wetting agents is well studied when applied to soils and / or crops, although many of the mechanisms of action are still not well understood. However, prior art does not motivate, suggest, or cause the right-to-see art to consider a solubilizing composition comprising an anionic surfactant and a wetting agent to facilitate the solubility of aqueous (or non-aqueous) fertilizer compounds and / or fertilizer compositions, each of which contains at least phosphorus (P) and / or potassium (K), and typically in concentrated form. Furthermore, the solubilizing composition according to this disclosure unexpectedly and surprisingly provides an effective means of supplying anionic surfactant to a soil in need.Anionic surfactants are more effective compared to non-ionic surfactants when applied to long-dry soils due to their negatively charged end.
[0062] The applicant is surprised that the solubilizing composition comprising the first anionic surfactant and at least two wetting agents provides increased solubility of fertilizer compounds and / or fertilizer compositions. The applicant is further surprised that the solubilizing composition as described increases the solubility of fertilizer compounds and / or fertilizer compositions containing phosphorus (P) and potassium (K) by preventing precipitation and / or gelation. Even more surprising is that the solubilizing composition of this description unexpectedly provides a means of supplying an anionic surfactant to soils that require it.The solubilizing composition of this product reduces the amount of water required to solubilize the fertilizer, decreases the number of fertigation applications (thus preventing soil compaction), and simultaneously allows the application of anionic surfactant to soils, improving the hydrophilicity of hydrophobic soils and further reducing the amount of water needed to adequately irrigate a crop. The anionic surfactant can now also provide advantageous adjuvant characteristics for the seed, plant, soil, or crop. Definitions

Only with N-Phuric 15 / 49 did the tested non-ionic adjuvant show some compatibility. The test results are shown in Figure 4.

[0112] Figure 2 (A to E) shows ORO-298-D different concentrations of ORO298-D together with liquid ammonium phosphate (10-34-0) in which Figure 2A shows 10% ORO-298-D with 90% 10-34-0; Figure 2B shows 25% ORO-298-D with 75% 10-34-0; Figure 2C shows 50% ORO-298-D and 50% 10-34-0; Figure 2D shows 75% ORO298-D with 25% 10-34-0; and Figure 2E shows 90% ORO-298-D and 10% 10-34-0.
[0113] Figure 3 (A to F) shows the solubility and miscibility of fertilizers with non-ionic adjuvant based on 20% ethoxylated alcohol in which Figure 3A shows 90% fertilizer (N-Phuric) and 10% non-ionic surfactant; Figure 3B shows 90% fertilizer (potassium thiosulfate) and 10% non-ionic surfactant; Figure 3C shows 90% fertilizer (zinc sulfate) and 10% non-ionic surfactant; qp Lonn / cznz / q / uιλι Figure 3D shows 90% fertilizer (K-Phite) and 10% nonionic surfactant; Figure 3E shows 90% fertilizer (10-34-0) and 10% nonionic surfactant; and Figure 3F shows 90% fertilizer (ammonium thiosulfate) and 10% nonionic surfactant.

[0115] The results in Table 4 show that commercially available nonionic surfactants (based on ethoxylated alcohol) are not compatible with fertilizers (typically concentrated fertilizers). However, the solubilizing composition according to this disclosure shows compatibility. This allows the use of more effective anionic surfactants, which are typically less expensive than nonionic surfactants and also provide better functionality for moistening soil that has dried out during a period of reduced or no rainfall. This compatibility allows a farmer to apply concentrated fertilizers to the soil without gelling or blocking, resulting in lower water usage and less soil compaction by vehicles transporting spray tanks across farmland.
[0116] Field tests: Initial field tests, such as screening the formulations in this disclosure, were conducted in a greenhouse. Three tests were performed: a) Plant vigor after 48 hours of germination (root assessment - length and number of branches); b) Wet root mass after 15 days of germination; c) Dry root mass after 15 days of germination.
[0117] In all screening tests conducted, it was demonstrated that ORO-298D improved root formation and root mass compared to treatment with a single concentrated fertilizer. The subject of this disclosure, described herein, enhances water penetration or water movement in the soil. In turn, the compatibility of fertilizers with the solubilizing composition described in this disclosure provides better availability of fertilizer (and nutrients, biostimulants, microbials, and minerals) (particularly nitrogen, phosphorus, and potassium) to a seed and / or plant, resulting in healthier crops and / or improved crop yields.
[0118] Additional field trials and greenhouse trials were conducted to support this disclosure, considering statistical data and including a soil movement study.
[0119] Additional field trials were conducted on corn and soybeans, two commercially important crops, in a furrow application of the solubilizing composition according to this disclosure together with fertilizer.
[0120] Soybean Field Trial. Experimental Design: Two-factor factorial in a 5-block randomized complete block (RMR) design. Application Method: Furrow application with / without 6-24-6 starter fertilizer at 2.5 gal / a. Main Findings: Furrow application of the solubilizing composition according to this disclosure ORO-298 at 24 pints per acre with / without starter fertilizer significantly improved emergence, plant vigor, initial root growth, and N, K, and P nutrient uptake by soybeans, compared to unfertilized or fertilized controls.
[0121] Figure 5A shows the effect of ORO-298 applied in furrow on soybean germination 15 days after planting. All rates shown are per acre. Error bars: standard error (p<0.05). Effects of ORO-298 observed with or without in-furrow fertilizer. 2.5 gal / acre using 6-24-6 fertilizer. In-furrow seed treatment. Mixture volume of 5 gal / acre. Soil: Milford silty clay loam. pH 6.8. Application of ORO-298 shows improved early germination. Figure 5B shows the effect of ORO-298 applied in furrow on soybean germination 22 days after planting. All rates are per acre. Error bars: standard error (p<0.05). Effects of ORO-298 observed with or without in-furrow fertilizer. 2.5 gal / ac using 6-24-6 fertilizer. In-furrow seed treatment. Mixing volume of 5 gal / ac. Soil: Milford silty clay loam. pH 6.8. The application of ORO-298 shows improved final germination.
[0122] Figure 6A shows the effect of ORO-298 applied in furrows on seedling vigor (soybean) and displays the total plant biomass 30 days after germination. Figure 6B shows the effect of ORO-298 applied in furrows on seedling vigor (soybean) and the number of root nodules per plant 30 days after germination. It can be seen that ORO-298 significantly improves soybean vigor.
[0123] Figures 7A, B and C show the effect of ORO-298 on in-furrow application on the absorption of macronutrients nitrogen, phosphorus and potassium, respectively, in soybeans.
[0124] Figure 8 shows the effect of ORO-298 in furrow application on the qq i Qnn / Qznz / q / uli biomass production per acre for soybeans. Calculated dry biomass produced (Kg / acre).
[0125] It is important to note that in soybeans (Figures 5 to 8), the application in rows of ORO-298 at 2-4 pints per acre with / without 6-24-6 starter fertilizer significantly improved emergence, plant vigor, early root growth, and nutrient uptake by soybeans, compared to the unfertilized or fertilized control.

[0128] With respect to the use of substantially any plural and / or singular term in this document, those skilled in the art may translate from plural to singular and / or from singular to plural as appropriate to the context and / or application. The various singular / plural permutations may be expressly stated herein for the sake of clarity. The indefinite article "a" or "an" does not preclude plurality. A single processor or other unit may perform the functions of several articles recited in the claims.

For example, as an aid to understanding, the following appended claims may contain the use of introductory phrases at least once and one or more to introduce claim recitations.However, the use of such phrases should not be interpreted as meaning that the introduction of a claim statement by the indefinite articles one or a limits any particular claim containing such an introductory claim statement to modalities containing only one of those statements, even if the same claim includes the introductory phrases one or more or at least one and indefinite articles such as one or an (for example, one and / or an should typically be interpreted as at least one or one or more); the same is true for the use of definite articles used to introduce claim statements.Furthermore, even if a specific number of a claim statement introduction is explicitly stated, those skilled in the art will recognize that such a statement should typically be interpreted as meaning at least the number referred to (e.g., the simple statement of two statements, without any other modifiers, generally means at least two statements, or two or more statements). Moreover, in those cases where a convention analogous to at least one of A, B, and C, etc., is used, such a construction is generally intended to be understood by someone skilled in the art (e.g., a system having at least one of A, B, and C would include, but not be limited to, systems having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.). In those cases where a convention analogous to at least one of A, B or C, etc.In general, such a construction is intended to be understood in the sense that someone skilled in the art would understand the convention (for example, a system having at least one of A, B, or C would include, but not be limited to, systems having A alone, B alone, C alone, A and B together, A and C together, B and C together, and / or A, B, and C together, etc.). Those skilled in the art will further understand that virtually any disjunctive word and / or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to encompass the possibilities of including one of the terms, any one of the terms, or both terms. For example, the phrase A or B will be understood to include the possibilities of A or B or A and B.
[0130] All numbers expressing quantities of ingredients, reagents, reaction conditions, etc., used in the specification shall be understood as modified in all cases by the term "approximately." Consequently, unless otherwise indicated, the numerical parameters set forth herein are approximations that may vary depending on the desired properties to be obtained. At a minimum, and not as an attempt to limit the application of the doctrine of equivalents to the scope of any claim in any application claiming priority to this application, each numerical parameter shall be interpreted in light of the number of significant digits and ordinary rounding approaches.
