Impact of Flyash on Soil physical Properties under Sunflower-Spinach-Sunflower Crop Rotation System in Central India

Abstract

Fly ash has tremendous potential as a nutrient supplement and plays a favourable role in increasing growth performance. Fly ash constitutes above 70% of the whole amount of residues formed in power plants through combustion of coal. The addition of Fly ash in soil improves or changes various physical, chemical and biological characteristics of soil. Fly ash is used for the improvement of the soil texture, water holding capability, density, bulk density, porosity etc. by using in different ratio with soil. For the growth of plant and crop yield fly ash is used as ameliorate in acidic soils. An experiment was conducted during the years 2015-17 adjacent to Yamuna River in the south of Allahabad city, India to find the impact of flyash on Soil physical Properties under Sunflower-Spinach-Sunflower Crop Rotation System. Findings of experiment reveal that the percentages of porosity, soil water holding capacity were increased while soil bulk density, soil particle density, soil solid space decreased as the dose of flyash increases under both cropping system even though after harvesting of crops there is slight decrease in these value.
