Abstract:

The amount of K fixed increased and percent of added K fixed of the soils decreased consistently with increasing rate of K application. Maximum percentage of K fixation was occurred at low rate of K application and minimum at higher dose of K application. The overall K fixation capacity of the soils was moderate. Recovery and fixation rate of K per unit of added K in the soils varied from 0.51 to 0.73 and 0.27 to 0.48, respectively. The unit fertilizer K requirement per unit increase in soil available K ranged from 1.36 to 1.94. Soils having medium to higher available and K reserve with lower K fixation and higher K recovery need frequent K application at lower dose, while soils having poor reserve of labile and non-labile K with moderate to high K fixation and lower K recovery need K fertilization at moderate dose for optimal plant nutrition.
