3 results about "Macro nutrients" patented technology

Nutrient compositions for plant growth are disclosed. A nutrient composition includes primary macronutrients, including nitrogen, phosphorus, and potassium, secondary macronutrients including calcium and sulfur. A nutrient composition may include micronutrients and additional secondary macronutrients, such as magnesium. Nutrient compositions including such nutrient sources exhibit advantageous plant growth. Hydroponic nutrient composition, water soluble powder, and plant growth mediums containing the nutrient composition, as well as methods of using the nutrient compositions, are further disclosed.

This invention relates to improving the efficiency of artificial and / or natural organic-based animal manure fertilizers by applying formulations containing poly(organic acid) [P(OA)] and / or its salts dispersed in a non-aqueous organic solvent delivery system (NOSDS). The use of NOSDS allows for the coating of all components of the fertilizer formulation with a layer of [P(OA)] and / or its salts, including but not limited to urea, manure, monoammonium phosphate (MAP), diammonium phosphate (DAP), solid micronutrients (such as lime, zinc chloride, etc.). The layer of [P(OA)] and / or its salts releases micronutrient metals and macronutrients bound to the soil as insoluble salts and complexes in a plant-available form. As a carboxylic acid, carboxylic anhydride, and / or carboxyl imide dispersed within NOSDS, the carboxyl group of [P(OA)] can be neutralized by one or more metals and / or nitrogen-containing compounds (such as ammonia, ammonium hydroxide, or organic amines) in the form of elemental metals, metal oxides, metal hydroxides, metal alkylates, and metal carbonates to form a stable dispersion that may contain fully complexed micronutrients and provide a carrier for transporting these nutrients to the soil and / or as a mulch to the surface of fertilizer particles and seeds.

The prepared suspension agent is a stable colloidal suspension obtained by hydrolysis of methoxy zinc aluminum hydrotalcite, the suspension agent can interact with a large amount of nutrient elements and trace nutrient elements required by crops, and form a stable suspension type liquid fertilizer, in the liquid fertilizer, fertilizer molecules are not easy to aggregate to form crystals and precipitate, and no solid-liquid stratification phenomenon occurs. The liquid fertilizer prepared based on the suspension agent has high light transmittance, does not block light, has strong adhesion to crop leaf surface, and can be used as a foliar fertilizer. The nutrition of the liquid fertilizer can be absorbed by crops in a short time, can effectively improve the chlorophyll content of crop leaves and improve the whole plant quality of crops, and shows that the liquid fertilizer has good effect of promoting the growth of crops. The method for preparing the liquid fertilizer by using the suspension agent is simple, the conditions are mild, and is suitable for practical popularization and application.
