Microbiota are less than 0.2mm and consist of bacteria, actinomycetes, fungi, algae and protozoa. Leeuwenhoek reported discoveries to Royal Society from 1670's on, firmly established existence of microbes. The fungi were then tested individually for growth on plastic films.

We have come a long way in developing our understanding of soil microbiology, ecology, and biochemistry, but have many milestones yet to meet.Molecular tools offer unparalleled opportunities to characterize soil biota in culture and directly from field soils. Effect of soil temperature • Microorganisms have been found growing in virtually all environments where there is liquid water, regardless of its temperature. Soil 1,3 is a multilayered surface complex of mineral and organic (humus) constituents present in solid, liquid, and gaseous states. Soils are excellent culture media for the growth of many kinds of microorganism, Size of Soil Organisms Macro or large (>2 mm) Meso or mid-size (2–0.2 mm) Micro or small (<0.2mm) Mite Earthworm Yeast Bacteria Alfalfa root Springtail, A single teaspoon of soil contains over 1,000,000,000 bacteria, about120,000 fungi and 25,000 algae. soil is the growing medium for our food without, Soil Water - .

The bacteria and the plant have a symbiotic relationship: the bacteria benefits by having food and shelter from the plant and the plant benefits by having nitrates produced by the bacteria. The establishment of the principal roles that microorganisms play in the biologically important cycles of matter on earth: the cycles of nitrogen, sulphur and carbon was largely Call for Papers: Emerging Pathogens, Food Security and One Health.
