The present invention comprises one or more organic solvents that create a non-aqueous organo solvent delivery system, (NOSDS), and one or more Organo Polycarboxylate functionalities, OPCF, that results in a stable, non-aqueous solution that can easily, safely, evenly and economically coat nitrogen source granules and/or be added to a mobile liquid form of a nitrogen source such as an aqueous dispersion, pressurized ammonia gas or molten urea and/or molten modified urea. Using these solvents provides more flexibility for nitrogen source manufacturers to produce nitrogen sources designed for a particular soil or plant. The liquid solutions are comprised of NOSDS and OPCFs and one or more of a) nitrification inhibitors, b) urease inhibitors, c) pesticides, d) fungicides, e) herbicides, f) insecticides and g) micronutrients.

Provided herein are compositions and methods for controlling enzyme-induced urea decomposition attendant to the application of solid or liquid urea-containing fertilizers to soils. More particularly, the subject matter disclosed herein is concerned with selected triarylmethane compounds as urease inhibitors and their use, either alone or in combination with tetrapolymer synergists. Further, the disclosed compositions have good storage stability, long-lived activity in soil, and avoid the toxicity issues common with present-day urease inhibitors used in agriculture.

The disclosure provides a composition including a corrosion inhibitor compound and an anti-emulsifier compound. The composition has a weight ratio of the anti-emulsifier to the corrosion inhibitor of about 20:1 to about 0.2:1. The composition may be used in a method of inhibiting corrosion of a metal surface. The method includes adding the composition to an aqueous system that includes the metal surface.
