Soil Health of Sandy Soil Profile Amended With Fly Ash : A Case Study

摘要

In order to assess the fertility status of soil admixed with fly ash in one time and repeat application at different intervals, pilot scale experiments were conducted by cultivation of vegetables, cereals and crops over a period of six years cropping system at Dodhar village, National Thermal Power Corporation (NTPC), Rihand Nagar, Northern India. The present work is an attempt to evaluate the effect of fly ash on soil health in terms of its fertility through certain biological indicators. Results revealed that soil enzymes mineralisation, mycorrhizal population, microbial biomass in terms of ATP activity were increased with one time application of fly ash at the rate of 25% (650 tonnes per hectares) over control (without fly ash) and repeat application at the rate of 5% (135 tonnes per hectare in every year). The long term effect of fly ash application on the quality of soil on biotic and abiotic properties along with crop and food quality were reported and discussed in this paper.
