Effect of flyash incorporation on soil properties of texturally variant soils
2000
Kalra, N. | Harit, R.C. | Sharma, S.K.
Modifications in soil properties caused by flyash incorporation in clayey, sandy-clay-loam, sandy and sandy-loam soils were evaluated. Flyash was collected from the National Capital Power Project, Dadri, Ghaziabad, UP. Ash incorporation treatments were 10%, 20%, 30%, and 40% ash by weight in the soil-ash mixtures. Moisture retained at field capacity increased with ash content in sandy-clay-loam, sandy and sandy-loam soils, whereas the reverse trend was noted for clayey soil. Moisture retained at wilting point increased with ash content for all the soils. The changes in moisture retention constants associated with ash incorporation were due to macro-and micro-particle size modifications. The pH of soil-ash mixtures decreased with ash content for clayey, sandy and sandy-loam soils, whereas the reverse trend was noted for sandy-clay-loam soil. Electrical conductivity of the mixtures increased with the ash content for all the soils. Organic carbon values increased with ash content for sandy and sandy-loam soils, whereas they decreased for clayey ad sandy-clay-loam soils. Modifications to the soil environment with incorporation of flyash need to be investigated on a long-term basis.
