Abstract
Agrochemicals have been used to eliminate different undesirable forms of li fe both in agriculture and in urban areas. The rural exodus and the increas e of labor costs in the agricultural areas have induced a greater use of he rbicides in crops, mainly of 2,4-D. Through adsorption-desorption processes the mobility of this herbicide can be evaluated. The effect of organic mat ter on sorption of 2,4-D in soil has been studied. Organic matter contribut ed to the increase of 2,4-D adsorption. The ideal concentrations of 2,4-D i n yellow-red Latosol soils were determined based on adsorption-desorption e xperiments.
