tailieunhanh - The micronutrients status and physio-chemical properties of geo referenced soils of Solapur district in Maharashtra, India

The present investigation was carried out for evaluation of the status of DTPA-Fe, Cu, Mn and Zn in relation with chemical properties in soils of Solapur district for this purpose representative soil samples were collected from different villages of Solapur district. The micronutrient and some important soil physico-chemical properties were investigated by using GPS and GIS techniques. Considering the critical limits of soil micronutrients, all soil associations were not adequately supplied with DTPA extractable micronutrients. Irrespective of land use, the DTPA extractable cationic micronutrients were positively related with organic carbon content and negatively related to calcium carbonate content. The DTPA– extractable Fe, Zn, Mn and Cu were extracted with diethelene tri- amine penta-acetic acid (DTPA) solution (Lindsay and Norwell 1978) and subsequently analysed with the help of atomic absorption spectrophotometer (Chemito203). The soil under the study were neutral to alkaline in reaction, safe in electrical conductivity and moderately calcareous in nature. DTPA-copper was recorded in medium quantity, while DTPA-iron, DTPA-zinc were low quantity and DTPA-manganese was high quantity. | The micronutrients status and physio-chemical properties of geo referenced soils of Solapur district in Maharashtra, India
