Does soil organic matter chemistry have influence on the sorption of diuron

The influence of organic matter chemistry on the sorption of diuron to soils collected from a small field (2 ha) was investigated. Organic carbon-normalized sorption coefficients (K ), determined by batch OC sorption, varied between 405 and 598 L kg amongst 10 A11 horizons and between 547 and 975 L kg amongst 11
