The present disclosure provides novel agricultural microbial inoculant compositions for uses in promoting plant growth, plant productivity and/or soil quality. The novel microbial inoculant compositions comprise one or more microbial species, one or more urease inhibitors and/or one or more nitrification inhibitors. The present disclosure also provides fertilizer compositions comprising said microbial inoculant compositions.

The present disclosure relates to an improved nitrification inhibitor composition and its use in agricultural applications.

The present disclosure relates to enhanced nitrification inhibitor dry fertilizer compositions, methods for making the same, and their use in agricultural applications.

The present invention relates to an improved nitrification inhibitor composition and its use in agricultural applications.

A composition comprises a nonaqeuous, liquid carrier, an inhibitor compound, and a colorant composition comprising an azo colorant. A method for making the composition is also provided. A method for making a fertilizer composition using the disclosed composition is also provided.

The present invention relates to the use of compounds of formula (I) for reducing nitrification and to compositions comprising the compounds of formula (I) and to agricultural mixtures comprising at least one compound of formula (I) and at least one fertilizer. Furthermore, the present invention relates to a method for reducing nitrification comprising treating a plant growing on soil or soil substituents and/or the locus or soil or soil substituents where the plant is growing or is intended to grow with a compound of formula (I) or a composition comprising a compound of formula (I).

Solvents useful with thiophosphoric triamide urease inhibitors, that provide stable solution of a thiophosphoric triamide, such as for distribution (in low or high concentrations) onto a fertilizer or other liquid or solid material that contains urea.

The present disclosure provides novel agricultural microbial inoculant compositions for uses in promoting plant growth, plant productivity and/or soil quality. The novel microbial inoculant compositions comprise one or more microbial species, one or more urease inhibitors and/or one or more nitrification inhibitors. The present disclosure also provides fertilizer compositions comprising said microbial inoculant compositions.

The present disclosure provides a liquid composition, comprising a dialkylcarbonate, and one or more phosphoric triamide compounds. Also provided is a liquid composition, comprising a C.sub.1-C.sub.4 alcohol, a vegetable oil or petroleum distillate, a surfactant, and one or more phosphoric triamide compounds. A further aspect of the disclosure provides a method for treating a nitrogen-containing fertilizer, comprising contacting a nitrogen-containing fertilizer with the liquid compositions described herein.

An inhibitor composition contains a urease inhibitor (e.g., alkyl thiophosphoric triamide) and a nitrification inhibitor (e.g., a natural nitrification inhibitor such as neem oil and the like), solubilized in a liquid medium comprising at least one organic solvent and, optionally, at least one stabilizer, useful in making fertilizer compositions (e.g., urea prill coatings) and in methods of fertilizing target plants.
