Fly ash, a solid waste being generated during power generation in thermal power plants, contains most of the plant nutrients in sufficient quantities, which holds great promise for its bulk use in agriculture as a soil conditioner for reclamation of acidic soil and as a source of plant nutrients for the deficient soils. The beneficial inherent properties of fly ash prompted us to study its effect on the growth of different root crops under green house conditions. The present article deals with yield of various root crops grown with fly ash and mass balance of the trace elements in soil, fly ash, and crop produce.
