A number of experimental studies have identified a clear role for soil microorganisms in soil aggregation 52, with bacteria and fungi typically having a larger influence than soil fauna.
Soil microbiology is the study of microorganisms in soil, their functions, and how they affect soil properties. [1] It is believed that between two and four billion years ago, the first ancient bacteria and microorganisms came about on Earth's oceans.
Soil microorganisms are classified into seven different categories; bacteria, fungi, virus, blue-green algae, actinomycetes, protozoa, and nematodes. Each of these groups has different characteristic features and their role in the soil they inhabit.
Most soil microbes can be classified as fungi, bacteria, archaea, protozoa, or viruses. It has been estimated that a single gram of soil can contain up to several billion bacteria alone.
This review discusses the role of microorganisms in soil carbon cycling and highlights the ecology of microorganisms in terms of broad and narrow processes in soil.
Soil microorganisms are broadly defined as a group of microscopic life forms that include bacteria, archaea, viruses, and eukaryotes like fungi. Soil animals comprise protozoa and nematodes (conventionally grouped as microfauna because of their micrometric size), springtails, mites and other microarthropods (mesofauna, mm), and earthworms ...
Soil microorganisms shape global element cycles in life and death. Living soil microorganisms are a major engine of terrestrial biogeochemistry, driving the turnover of soil...
