Abstract

he application of ammonia-based fertilizer (anhydrous ammonia, aqua ammonia, and urea) initially increases soil pH. Changes in soil pH influence dissolved organic carbon (DOC) concentrations in soil solution and herbicide sorption characteristics to soil. A batch study was conducted to evaluate the influence of ammonia application on atrazine [2-chloro-4-(ethylamino)-6-(isopropylamino)-l, 3, 5-triazine] adsorptionand desorption characteristics to a Brandt silty clay loam (fine silty, Pachic Udic Haploborolls) and Ves clay loam (fine silty, mixed mesic typic Hapludalf). Ammoniatreatment rates were equivalent to N concentrations found in bands when 0, 100, and 200 kg of N ha-1 were injected to soil. Atrazine treatments were 0 (0.01 M CaCD, 2.08, 6.57, or 50.80//mol of atrazine L_1. . . .
