In: Egyptian journal of soil science 2004 v .44 (3)Summary: Soil samples (0-30cm) of five different soils were used to investigate the use of the power equation to predict K dsorption kinetics. These samples were collected from EI- Tahrir, Ganaklis, Bourg EI-Arab, Maryout and EI-Giza regions, representing different origins. Soils were initially treated with 0-250 mg K kg as KBr. The effects of initial Exchangeable K, contact time (5, IS, 30 & 60 min), dilution (10: 1,40: I, 100: I & 300: I water I soil ratio) on K desorption were investigated. Parameters of the power equation were calculated and compared for the different soils. This equation succeeded in describing the kinetics of K desorption in the studied soils.
