Abstract: Fly ash is the major waste product generated in coal based industries and thermal power plants. Fly ash can be utilized in agricultural field crops for improving soil properties and increase nutrient supply. The properties of Fly ash (FA) and Pond ash (PA) indicated that these are having good water holding capacity and have more of sand and silt particles. The pH of ashes were alkaline. These were found to be good sources of potash, calcium, magnesium, sulphur and micronutrients. The heavy metal content of FA varied more than that of PA. The level of radio activity in both ashes were not significant but double the soils. The use of FA and PA with or without FYM to different crops enhanced moisture holding capacities of soil (MWHC, FC and PWP, 40.53% to 46.80%, 21.10% to 23.20% and 8.40% to 8.80, respectively). The soil chemical properties did not very much. The micronutrient contents of soil were also influenced by these ashes. The heavy metal contentin soil due to FA application varied more than that of PA application in black soil, however it is less significant in red soils. Application of ashes at the rate of 30 t/ha along with FYM in both red soil and black soil was found beneficial.
