Abstract


The results of a laboratory incubation study with laterite soil on the fixation of major plant nutrients showed that with increase in the concentrations of added NH4, P and K the fixation of the respective nutrients also increased. The fixation of NH4 was maximum under constant moisture level, while the fixation of K was maximum under alternate wetting and drying. The fixation of P was not influenced by the changes in mointure levels. The NH fixation in the laterite soil was not affected by the presence of K, while K fixation was maximum irrespective of levels of nitrogen added. Fixation of the respective nutrients increased with increase in the period of incubation.
