Abstract: Flyash can be used for reclaiming the problem soil and enhance the crop productivity depending upon the nature of soil and flyash. It may improve physical, chemical and biological properties of problem soils and enhance the available macro and micronutrients for plants. The high concentration of elements (K, Na, Zn, Ca, Mg and Fe) in flyash increase yield of agricultural crops. However, application of flyash, particularly unweathered ones, shows a tendency of accumulating elements like B, Mo, Se and Al. The accumulations of these elements to toxic levels are responsible for reductions in the crop yields and consequently influence animal and human health. This review explores the possibility of using flyash to improve the soil environment and subsequently increase the growth and yield of crops.
