Bentonite Impact on Soil Properties and Biological Activity in the Face of Drought : A Review

Abstract The clay mineral bentonite has received a lot of attention for its potential to reduce the harmful effects of drought on soil health and biological activity. Reduced enzymatic activity and microbial diversity are two negative outcomes of the drought’s impact on soil quality. Bentonite, however, has been shown to aid in the restoration of biological functions in drought-affected soils. Bentonite’s function as a soil moisture retainer is an important consideration. Bentonite acts as a reservoir, trapping water within its layers due to its high water-holding capacity and ability to form a gel-like structure. This capacity for water retention can reduce the negative impact of drought on soil organisms, making conditions better for enzyme activity and microbial life. Bentonite has…
