Responses of biogeochemical properties of different soil aggregates to glyphosate application and degradation
Abstract
Relative abundances of adsorption sites increase with the specific surface area of soil particles and aggregates. In turn, larger sorbed-phase distributions may attenuate pesticide biodegradation rates and ecotoxicological effects. Thus, soil aggregate size may be an important determinant of the fate and ecotoxicological effects of glyphosate and its metabolite aminomethylphosphonic acid (AMPA). We investigate the dynamics of glyphosate degradation, AMPA formation, AMPA degradation, and soil biogeochemical properties over 30 days, in soils composed of aggregates of various sizes: bulk soil (
