Abstract: | Summary Vertisols from field plots fertilized continuously with P, K, FYM alone and in combination at the rate of 60 kg P2O5, 30 kg K2O and 1.5 ton FYM per ha were tested for different forms of Fe and Mn as a consequence of continuous cropping with sorghum and wheat. The transformations that occurred in different forms of plant-available iron were greater than those of Mn. Exchangeable and easily reducible Fe contents were markedly influenced by treatments. In manganese, transformations of easily reducible to exchangeable forms were conspicuous. |
