Document Type: Proceeding Paper

Part of: Planning Now for Irrigation and Drainage in the 21st Century


Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption relationships for predicting pesticide transport are reviewed. Hysteresis of desorption and relationships for predicting linear equilibrium coefficients are discussed.
