Potassium Fixing Capacity of Some Base Unsaturated Western Ghat Soils of Karnataka Under Paddy Land Use Cover

摘要

The Potassium Fixing Capacities of 20 representative soils of Western Ghat regions of Karnataka were collected and determined for Potassium Fixing Capacity by using standard procedure. The Potassium Fixing Capacity of soils of Chikmagalore, Shimoga, Hasana and Coorg districts varied from 0.23 to 0.26 cmol (p+) kg"1,0.30 to 0.35 cmol (p+) kg1,0.19 to 0.25 cmol (p+) kg"1 and 0.22 to 0.26 cmol (p+) kg1, respectively. However, the soils of Shimoga had relatively high Potassium Fixing Capacity and those of Hasana had low Potassium Fixing Capacity compared to the soil of other districts. The amounts of K fixedsignificantly correlated with the clay content and the pH content of soils.
