Abstract

Studies of the methods of accumulation and rational use of moisture were carried out on black earth of southern heavy loamy, dark chestnut loamy and meadow-chestnut light loamy soils of the Pavlodar region. It has been established that the application of the snow retention technology developed by Pavlodar Research Institute of Agriculture by means of leaving a continuous scrubbed stubble or stern wings during the harvesting of grain crops by a special combing device providing an increase in moisture reserves in the black earth of southern spring crops before sowing is an important means in solving the problem of optimizing the moisture
content of soils in agrolandscape areas. 25,8-26,3 mm and practically not inferior to clean rocking pairs, but with a higher efficiency of soil fertility conservation and protection from wind erosion. The use of zero and intensive technologies for the preparation of predecessors (abandonment of high stubble, seeding of the wings, spreading of chopped straw, weed control techniques, etc.) contributes to increasing the moisture availability of dark chestnut loamy soils before sowing of agricultural crops by 30,5-33,0 mm and 15,6-27,1 mm, and on meadow chestnut soils - by 17,8- 20,2 mm and by 11,5-19,2 mm, respectively, compared with traditional technology.
