Soil is one of the national wealth and belongs to the most important strategic natural resources. The historical experience of the civilization development shows that the rise and decline of any state directly depends on its soil fertility. Reduction of soil fertility is a problem not only at the state level but a universal problem. The Food and Agriculture Organization (FAO) informs that about 70% of the earth dry land area is represented by the unproductive land, which is limited by the soil, climate, relief and economic conditions. The productive soil decreases annually in the world.
The solution of the food problem is impossible without the involvement of natural unproductive and degraded soil areas in the agricultural production.
