Upload NowThis article provides a notes on the Gypsum Requirement (GR) of soil. The main principle for the reclamation of sodic or alkali soils is to replace exchangeable Na by another cation calcium (Ca2+). Of all calcium compounds, gypsum (CaSO4.2H2O) is considered the best and cheapest for the reclamation purpose. Calcium (Ca2+) solubilized from gypsum replaces […]

Short Notes on Clay-Humus Complex
Article shared by :
This article provides short notes on clay-humus complex. It is evident that various clay minerals can bind humus substances through some linkages known as clay-humus complex. Many investigators consider that the complexes between humus substances and clays are probably formed by bridging through the exchangeable cations like Ca, Mg and Al. Besides this, they also […]
