DISTRIBUTION OF MICRONUTRIENTS IN LOWER BHAVANI PROJECT COMMAND AREA SOIL PROFILES

Abstract

                                The study of distribution of micronutrients in major soils of Lower Bhavani Project Command Area revealed that total and available Zn.Fe and Cu decreased with depth in Lithic Haplustalf, Typic Ustochrept, Typic Haplustalf and Typic Chromustert, while total Mn decreased only in Lithic Haplustalf and Typic Ustochrept. But in Typic Ustifluvent, there is an irregular distribution of both total and available Zn,Fe, Cu and Mn. All the micronutrients are in sufficient level except Zn indicating the need for ZnSO4 for sustainable crop production. All the micronutrients are closely related with organic carbon and clay.
