Abstract

Adsorption-desorption of pendimethalin, fluchloralin and oxadiazon was studied on sandy loam and clayey soils. Pendimethalin showed maximum adsorption on both the soils. However, oxadiazon was the least adsorbed. Organic matter content of the soil was responsible for adsorption of the herbicides, which was evident by the low KOC. values for clayey soils. In sandy loam soil, fluchloralin recorded maximum desorption followed by oxadiazon and pendimethalin.
