Abstract

To study the available Zinc content of the soil as influenced by the application of graded levels of zinc fertilizer and zinc solubilizing bacteria under simulated moisture conditions in neutral and sodic soils, an incubation experiment was conducted during Jan., 2014 and the DTPA-Zn was analysed at monthly interval starting from 30th day after incubation. The results indicated that available zinc content was found to be more in the neutral soils as compared to sodic soils at all the stages of incubation irrespective of moisture. In both the soils and moisture regimes, the zinc solubilizing bacteria inoculation enhanced the available zinc content of the soils.
