This invention relates to inhibiting leaching of crop treating chemicals into the ground water, aqua-system and surrounding soil of the treatment site by contacting the plant or plant site with an effective leach inhibiting, plant tolerating amount of a nitrogen-containing copolymer having pendant nitrogeneous groups which contains between about 40 and about 98 wt. % of monomer unit A defined by the formula [Figure] A. and 2 to 40 wt. % of comonomer unit B [Figure] B. wherein X is hydrogen, a C1 to C22 radical of the group alkyl, alkoxy, aryl, alkaryl, aryloxy and alkaryloxy; R2 is hydrogen or －(CO)y′OR′; R, R1, R3 and R′are each selected from the group of hydrogen and lower alkyl; R6 is hydrogen or [Figure] x, y, y′and z each have a value of 0 or 1; a has a value of from 2 to 4; Z is －O－or －NH－ Y is an optionally quaternized group of [Figure] and R4 and R5 are hydrogen or lower alkyl except that at least one of R4 and R5 is lower alkyl.
