Аннотация: Possibilities for implementation of the Black Sea sapropel bottom deposits as an ecological fertilizer for the purpose of re-cultivation of waste lands are discussed. The soil layer occupies an insignificant part of the earth weathering crust (from several cm to 1 or 2m) and it comes to be the basis for life activity of the organism world. Soil-formation is an extremely complex process, especially in the conditions of the desert regions. Because of the active interference of the human society in Nature, at today’s stage of its development, the value of the soil cover grows rapidly. Humus and clay minerals are the main ingredients of soil. They adhere to grains of sand and form aggregates which permit microorganisms, nutritives and air to penetrate to plant roots. It becomes clear that expansion of the arable desert areas and their transformation into earthly oases is the prime task for countries like Syria, Saudi Arabia, UAE (United Arabic Emirates), Israel, etc. During last years, deep-water organic mineral (sapropeloides, diatomic, coccolithophoridic) sediments of Black Sea, come to be a subject of specialized research, purposing their application as natural ecological fertilizer and for re-cultivation of desert areas.
