CO-APPLICATION IMPACT OF SEWAGE SLUDGE AND FLYASH ON SOIL NUTRIENT INDEX AND SPINACH IN INCEPTISOLS OF PRAYAGRAJ, U.P., INDIARaghu Nandan Singh Khatana, Tarence Thomas, Narendra Swaroop, Akshita Barthwal and Tarun KumarAbstract The present investigation was to determine whether it would be feasible to grow Spinach in amended soil utilising sewage sludge and fly ash. Different types of nutrients and heavy metals are found in both soil amendments and for growth of the plant and crop yield they are used as ameliorate in acidic soils. In the research trail, soil properties like Bulk density, Particle density and pH are found to be non-significant and Pore space, Water holding capacity, EC, OC, Nitrogen, Phosphorus, Potassium, Iron, Manganese, Zinc and copper are found to be significant. The nutrient index was also examined and it was identified that the Fe has a low fertility nutrient status followed by OC, N, K, Mn with medium fertility nutrient status and P, Zn, Cu with high fertility nutrient status. |
