Abstract | |||||
| The effects of intensive fertilization and cropping on micro nutrients content of soil, solution and plant samples were studied. The treatments selected for this study were control, N, NP, NS, NPK and NPKSZn. The samples were analyzed to see the concentration of Zn, Cu, and Mn. Application of N showed an increase only in available Fe and Mn over control. The long-term application of P (TSP) increased available, total and soil solution content of Zn, Cu, Fe and Mn and uptake by crops. Fe and Mn content of soil solution was high in wet period than in dry period while a reverse was noted in case of Zn and Cu. | |||||
