1. A liquid agricultural composition comprising
at least one of a nitrification inhibitor, a urease inhibitor or a mixture thereof; an organophosphate solvent of formula (VIII): wherein R1, R2 and R3, are each independently chosen from H, a C1-C16 alkyl group, a C1-C16 alkenyl, group, a C1-C16 alkoxyalkyl group, a C7-C30 alkylarylalkyl group, a C7-C30 arylalkyl group, or an aryl group; provided that at least one of R1, R2 or R3 is not H; and optionally, at least one co-solvent selected from:
(a) at least one dioxolane compound of formula (III): wherein R6 and R7 individually comprises a hydrogen, an alkyl group, an alkenyl group, or a phenyl group, wherein n is an integer of from 1 to 10;
b) at least one dibasic ester;c) at least one compound of formula (IIa):
R3OOC-A-CONR4R5 (IIa), wherein R3 comprises a C1-C36 alkyl group; wherein R4 and R5 individually comprise a C1-C36 alkyl group, wherein R4 and R5 can optionally together form a ring; and wherein A is a linear or a branched divalent C2-C6 alkyl group;
d) at least one alkyldimethylamide;e) at least one alkyl lactate;f) ethyl levulinate;g) at least one alkyoxyalcohol, ether alcohol, amine alcohol, amino alcohol or alcohol;h) at least one glycerine or glycerine derivative;i) at least one alkylene carbonate; orj) dimethylsulfoxide. |
