Major factors influencing the distribution and density of population are described as under: 1. Most of the soil bacteria, blue-green algae, diatoms and protozoa prefer a neutral or slightly alkaline reaction between PH 4.5 and 8.0 and fungi grow in acidic reaction between PH 4.5 and 6.5 while actinomycetes prefer slightly alkaline soil reactions. Soils 1 and 2 have the same soil pH values; however, they have different Buffer pH values. Soil Buffer pH -- a measure of the soil’s potential acidity (H+) due to that of the soil solution and the exchange sites of the soil colloids themselves. This soil volume is the sum of the volume occupied by soil solids and volume occupied by air. The heterotrophs utilize the energy liberated during the oxidation of complex organic compounds in soil, while autotrophs meet their energy requirement form oxidation of simple inorganic compounds (chemoautotroph) or from solar radiation (Photoautotroph). They are known to be influenced by biotic and abiotic factors, such as plant cover or edaphic parameters. Brief description function of microbes in soil Decomposition of organic matter Release of nutrients from plant residue Fixation of atmospheric nitrogen. How easily are energy sources metabolized?
