A field experiment was conducted in Allahabad District of Uttar Pradesh to test the possibility of utilizing fly ash, in afforestation of sodic soil with Albizia procera, as a substitute of fertilizers and amendments. Fly ash proved to be a good substitute of rice husk, was superior. Similarly the treatments where fertilizer was replaced with fly ash have also shown better performance of plant.

The use of heavy metals along with the associate risks of metal pollution has increased to a great extent over the recent times. Cadmium is one of the most harmful toxic metals. This metal is being increasingly consumed in the industries. Its pollution potential, has therefore given rise to the necessity of removal of cadmium from wastewater.

The objective of the present study is to assess the migrating behaviour of nickel and chromium through the soil collected around an ash-pond site through laboratory studies and an undertaking of contaminant (Nickel and Chromium)- soil interaction phenomena for unraveling the transport mechanism of nickel and chromium through soil and ground water with an attempt to validate 2 D mathematical modeli

Fly ash is an industrial waste generated from thermal power plants. A large part of fly ash produced is disposed of with very high environmental risk.

In view of the environmental problems generated by large-scale production of fly ash, increasing attention is now being paid to the recycling of fly ash as a good source of nutrients. Because
availability of many nutrients is very low in fly ash, available ranges of such nutrients must be improved to increase the effectiveness of fly ash as a soil amendment. In our experiment, we assessed the possibility of increasing total nitrogen, total phosphorus, total potassium and micronutrients in fly ash through
