Abstract: The presently disclosed subject matter is directed to nitrogen-stabilizing compositions containing nitrogen stabilizers condensed with organic acid anhydrides. The resulting condensation products exhibit numerous beneficial properties such as increased thermal stability and the ability to provide a controlled and continuous release of nitrogen stabilizer, thereby promoting increased nutrient availability to plants and crops.

Abstract: The presently disclosed subject matter is directed to nitrapyrin complexes and mixtures as well as syntheses thereof finding particular utility in agricultural uses. For example, these complexes or mixtures can be directly applied to soil, or can be applied in combination with fertilizers to increase nutrient uptake and to inhibit nitrification and urease hydrolysis. More particularly, the subject matter is directed to nitrapyrin complexed or mixed with monoacids that can be further functionalized. Other uses of the nitrapyrin complexes and mixtures, and compositions containing the nitrapyrin complexes and mixtures are disclosed.
