【 摘 要 】

During the drought season agronomic crops get into a critical situation when a lack of moisture and nutritional chemicals can result in plant wilting and crop loss. To prevent 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 the soil was determined in two months after cultivation and applying of liquid ameliorants according to the National Standard 28268-89 "Soils. Methods of moisture determination, maximum hydroscopic moisture and permanent wilting coefficient of plants". In this case, received values of filtration filters and soil porosity show qualitative soil cultivation for crop growing.
