Define the term - Soil Flora

Higher plants are, by and large, the most important group of primary producer organisms in the whole soil. The continuous decay of plants and plant roots contributes to the formation of soil microorganisms and thereby changes the soil properties, viz. soil aggregation, cation exchange capacity, water, air and nutrient retention capacity. The proliferating roots exert tremendous pressure on surrounding soil particles, thereby compacting and aggregating them. When the roots decay, the vacant space makes room for water and air to move in. The microbes in the flora class are bacteria, actinomycetes, fungi and algae. This is also their order of abundance.
