Abstract

The article presents the results of the study of the method for condensation of atmospheric vaporous soil moisture. The method is aimed at improving fertility of soils, which are highly prone to desertification. For soil aeration we have developed a working tool of mole plough, which has no analogues (A.S. № 1656064). It consists of a horizontal knife in the form of parting wings. An 80 mm mole expander is located in the center of the knife, 60 mm mole expanders are located at the ends of the tool. The working tool of the mole plough is attached tightly (by welding) to the vertical knife of the mole plough. The mole plough is hung on a heavy crawler tractor. The working tool of the mole plough forms many molehills at a specified depth in the soil after a single operation and many cracks in the soil profile of vertical and horizontal directions. Due to the regular changes in atmospheric pressure in the desert, atmospheric air is constantly circulates in the molehills and cracks. Due to the difference in the temperature of “soil-atmosphere” system, atmospheric vaporous moisture condenses in the molehills and cracks of soil profile. Aeration of soils, which are prone to desertification, with the developed working tool of mole plough increases condensation of vaporous moisture by more than 23 mm/ha daily in a meter layer of soil profile during the hot season, improves biological productivity by 1.5-2 times or more. It increases the number of livestock per unit area, which ensures food security of populations in deserts.
