The aim of these is to further give full play to soil's productive potentiality and improve mankind's existence environment. The main contents of soil ecological study should include: relationship of soil fertility with state factors; role of soil pool in matter flow and energy transformation; soil productivity; establishment and maintenance of relative equilibrium position of soil and problems of methodology.
