| dc.description.abstract | The behaviour of potassium in soil is rather complex. Its solubility ranges from easily soluble form in the soil solution to insoluble form in the potassium bearing minerals. Fixation of potassium adds to reserve of pool of soil. It refers to the fraction of K not extracted by neutral salt solution of NH4OAC and this parameter largely decides arid controls the release of K, from the soil. The response of crops to added K is indirectly influenced by the magnitude and extent of K fixation. In ca-deficient Alfisols K -ca equilibria is important because K application is likely to reduce the absorption of Ca and Mg in the plant system. Modifying influence of N in this respect is also important. Based on the above mentioned consideration, its was aimed to study the fixation release and nature of interaction of potassium with N and Ca in Alfisols of Chotanagpur region.Some important physical chemical properties and different forms of K in selected soils of different series were tested for the fixation and release Studies | |
