Soil Microbiology It is branch of science dealing with study of soil microorganisms and their activities in the soil, their functions, and how they affect soil properties form a very small fraction of soil mass (volume of less than 1%) In the upper layer of soil (top soil up to 10-30 cm depth i.e. soil organisms & there benifficial and harmful roles. It is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of wastes, and as … SOIL MICROBIOLOGY • Soil microbiology is the study of organisms in soil, their functions, and how they affect soil properties. Although soil biota, which includes living roots and soil organisms, occupies a very small fraction of the total soil volume (<0.5 %), it has tremendous influences on soil properties and soil processes. Soil biology plays a vital role in determining many soil characteristics, yet, being a relatively new science, much remains unknown about soil biology and about how the nature of soil is affected.

An interesting feature of soil is its living biology—yes, it is alive. It also provides habitats colonised by a staggering variety of microorganisms. Centre for Advanced Studies in Earth Science Scientists say that most fertile soils contain more living organisms in a handful of soil than there are people on planet Earth (approx. Organisms live in the soil surface, sub-surfaces, and even in the depths of the earth at the highest temperature. Science) FJWU 2. 24 At extreme high temperatures of 58℃, soil macro-organisms die because of the unfavourable temperature of the soil (Bristow, 1998). Soil organisms.
