Soil might look dirt but it is far more interestings; living in the soil or plant roots, bacteria, fungi, actinomycetes, algae, lichens, protozoan, nematodes etc. These exist in great diversity among various microorganisms and even with in a group of microorganisms, dependng on the habitat and environmental factors. Soils are formed from a stew of geological ingredients or parent material (rock and mineral), water and billions of organisms. The interaction between climate, parent of soil properties that are unique to the soil type and climate. It has been proposed that a micorbe should be considered as a new state symbol in the company of state animals, the state bird,
