Electrophoretic Fractionation of the Soil Humic Acids of Chakrata Himalayas (U.P.)

Abstract

Soil humic substances of Chakrata Himalayas was subjected to electrophoretic examination for their molecular weight make up. The humic substances of the soils under deodar, spruce, fir, oak and kharsu were having higher molecular weight than under chir and kail with accumulation on the surface horizons rather than sub-surface ones. Since the molecular make up of the humic substances is regarded as the fertility indicator in the soil, it was concluded that the soils under, deodar, spruce, fir, oak and kharsu were more fertile than the soils under chir and kail.
