Kinetics of non exchangeable potassium release from K depleted Ustochrepts



Kinetics of non exchangeable potassium release from K depleted Ustochrepts



Journal of Potassium Research 8(1): 38-43



The kinetics of non-exchangeable potassium release from nine K depleted surface samples of varying texture (Ustochrepts) of the Union Territory of Delhi were studied with H resin at two temperatures (25 degrees C and 35 degrees C). The potassium supplying capacity of the soils was studied in a pot experiment with mustard and wheat as test crops. The rate of release of non-exchangeable K by H-resin increased with time and fitted well to kinetic equation of first order opposing reactions.
