The present application generally relates to a method for the manufacture of a liquid composition essentially consisting of an organic solvent of the type glycol ether and a urease inhibitor of the type phosphoric triamide and products obtained therewith.

The present invention relates to improving the efficiency of man-made and/or natural organic-based animal manure fertilizers by administration of formulations containing poly(organic acids), [P(OA)]s, and/or their salts dispersed in a Non-aqueous Organic Solvent Delivery System (NOSDS). Utilizing a NOSDS allows for coating all components in a fertilizer formulation including but not limited to Urea, Manure, mono-ammonium phosphate (MAP), di-ammonium phosphate (DAP), solid micronutrients such as lime, zinc chloride, etc.) with a layer of [P(OA)]s and/or their salts that liberates, in a plant available form, the micronutrient metals and macronutrients, that are bound as insoluble salts and complexes in the soil. The carboxylic groups of a [P(OA)] that can exist within the [P(OA)] as carboxylic acids, carboxylic anhydrides and/or carboxylic imides, dispersed within the NOSDS, can be neutralized with one or more metals in the form of elemental metals, metal oxides, metal hydroxides, metal alkylates and metal carbonates and/or nitrogen containing compounds such as ammonia, ammonium hydroxide or organoamines to form a stable dispersion that can contain completely complexed micronutrients and provide the vehicle for the delivery of these nutrients to soils and/or as a coating to the surfaces fertilizer granules and seeds.

A mixture comprising 20% to 35% by weight of water and 15% to 19% by weight of 3,4-dimethylpyrazole, based on the overall mixture that adds up to 100% by weight, and phosphoric acid in a molar ratio to 3,4-dimethylpyrazole of at least 1:1 is used for coating of nitrogen-containing fertilizers.

This disclosure relates to a semi-humic material, and compositions comprising the same, obtained from leonardite ore and a non-humic organic carbon source and a process for obtaining the same. Also described are methods for maintaining more available nitrogen and phosphorus in the plant root zone and minimizing premature leaching and loss of the nitrogen and/or phosphorus into the atmosphere, surface waters and/or subsurface ground water.

An inhibitor composition contains alkyl thiophosphoric triamide (or a mixture of alkyl thiophosphoric triamide and dicyandiamide), dissolved in a liquid medium comprising at least one organic solvent and at least one amine stabilizer, is useful in making fertilizer compositions and in a method of fertilizing target plants.

A method for applying an agrochemical mixture to a working area of a field using a vehicle moving on the field is described. Thereby, a solid fertilizer is spread on the working area using a fertilizer spreading device mounted on the vehicle and a liquid fertilizer additive is sprayed on the working area using a field sprayer, mounted on the vehicle separately from the fertilizer spreading device. Therein, the liquid fertilizer additive is prevented from coming into contact with surfaces of the fertilizer spreading device, which also come into contact with the solid fertilizer. Moreover, a vehicle for applying an agrochemical mixture to a working area of a field while moving on the field is also described.

The present disclosure relates to a novel highly concentrated phosphoric or thiophosphoric triamide formulation with enhanced stability against crystallization or freezing under extended exposure to low temperature of 0 C. or below. It also provides a method to make and use such formulations.

Reaction products and methods for making and using such reaction products are provided. For example, a reaction product comprising an adduct formed from urea, formaldehyde, and a urease inhibitor is described, which can be provided in various forms. For example, such a reaction product can be in the form of a solid or solution. Such a reaction product can also be combined with one or more additional components, including but not limited to, additional urease inhibitor and/or a nitrogen-based fertilizer composition.

The present disclosure relates to a high concentration nitrapyrin liquid formulation with improved stability against crystallization and/or freezing under exposure to low temperatures of 0 C. or below, and methods to make and use such a formulation.

Provided are an electron transport chain module from a eukaryotic organelle and an application thereof in biological nitrogen fixation. The electron transport chain (ETC) module is composed of the NifJ protein from Klebsiella oxytoca and a ferredoxin from plant chloroplasts or leucoplasts; plant-type ferredoxin-NADPH reductase (FNR) and the FdxH or FdxB protein from Anabaena; or an FNR and a Ferredoxin protein from plant organelles.
