Abstract

Microflora is the soil microbes present in the top layer of soil, along with the plant roots. They include bacteria, actinomycetes, fungi, and algae. By decomposing organic matter and adding humus, they augment the fertility of the soil. They are significant in nutrient cycling, rock and mineral weathering, and stabilizing soil aggregates. The unnecessary anthropogenic activities and inappropriate quantities of chemicals, especially organo-chorine pesticides, to increase agricultural productivity threaten the soil microflora and the healthy soil structure. Hence, a shift towards alternative cropping systems is essential for protecting the delicate ecological balance. This chapter discusses the influence of soil microflora on soil fertility, the impact of organochlorine pesticides on the soil microflora, and methods to reduce pesticide toxicity on soils.
