Soil, minerals , salts etc etc are all life less bodies. Its life that changes the structure of these bodies , due to putrifaction , chemical reaction and so on.Therefore all the organic matter of life like fallen trees, dead animals, birds, insects and also humans all get burried under soil and It is the bacteria which is primarly responsible to break all these organic matter to different chemical composition like salts, minerals , phospates etc. The soil digests and absorbs all the organic matter with the help of bacteria and hence it is important to soil.
