The distribution and dissipation of herbicides on soils are dynamic and unique processes for each soil-herbicide relation. In this research, the half-life of diuron was determined in five soils (Red-Yellow Latosol, Red Latosol, and Yellow Latosol), with different pH values. Diuron concentrations were determined in samples of each soil collected at eight different times (1, 8, 15, 22, 36, 66, 96 and 156 days after herbicide application at 3.0kg ha-1). Part of each soil sample was used to quant...
