【 摘 要 】

During the drought season agronomic crops get into a critical situation when a lack of moisture and nutritional chemicals may lead to a wilt of plants and crop loss. For preventing of the following situation it is proposed to apply liquid ameliorants in the process of subsurface tillage which can accumulate moisture in a soil. The introduction of ameliorants offered to carry out work on liquid ameliorants directly into the root soil layer, to create favorable conditions for the development of the plant. Also, when making soil ameliorants preventing the leaching of their streams generated from rainfall and meltwater. Experimental studies have shown that zero tillage with simultaneous application of liquid ameliorants (in the process of experiment was used urea-ammonium nitrate) can increase soil moisture at cultivation depth from 22 to 47%. Moisture of soil determined after two months after cultivation and applying of liquid ameliorants according to the National Standard 28268-89 "Soils. Methods for determination of moisture, maximum hydroscopic moisture and moisture of steady plant fading". In this case, received values of filtration filters and soil porosity show qualitative soil cultivation for crop growing.
