In the formation of the soil, the role of living organisms is huge.
The soil is the upper layer of the lithosphere and is created thanks to the activities of living organisms.
Living organisms that inhabit the soil affect the properties of the soil, both biological and physical and chemical.
Residents of the soil, participate in complex soil -forming processes and movement of nutrients to its upper layers.
Bacteria, soil animals and mushrooms processing dead plants, enrich the soil with organic substances.
Many microorganisms entering into symbiosis with higher plants, have the ability to fix nitrogen from the atmosphere, which also improve fertility.
Animals like mice, moles, rainworms, etc. Paying their moves and holes in the soil, loosen it, and their excrement and food remnants also enrich it.
