Potassium Fixation Capability of Some Acid Alfisols Developed under Tropical Environment in Eastern India

A. Seal, R. Bera, K. Mukhopadhyay and P. Bhattacharyya

Abstract:
K fixation of soils is an important phenomenon affecting the status of soil K and its availability to crops. Four typifying pedons representing acid alfisols in eastern India were studied for their K fixation characteristics. Available K of soils increased with the rate of added K in all the soil series. Percentage of K fixed increased upto 800 mg kg-1 and maximum fixation levels were observed at 100 mg kg-1. Maximum K requirement per unit increase in available K of soils was observed in Hatiapathar series, which connect well with the low recovery rate of K in these soils. Significant correlation obtained for K recovery, K fixation and K requirement with pH, clay percent and CEC may indicate that these properties play dominant role in the soil K dynamics.
