Impact of agrotechnical measures and reclamation protective forest plantations on soil deflation in Rostov region

Purpose: to study the deflation manifestation patterns on Rostov region soils in cold and warm periods of year, depending agricultural background, projective cover soil surface by plants availability reclamation protective forest plantations. Materials methods. Deflation studies were being carried out Aksai Orlovsky districts from 1970 2022. Conventional research methods including measurement wind speed anemometers, used, layer displaced was determined method pins dust collectors authors own design. Results. During period storm April 14 21, 2003, influence position amount stubble removal under various tillage determined. chisel tillage, largest noted – 250 pcs/sq. m, standing one 110 m lying 140 m. At same time, there a decrease velocity 10.9 m/s at height 0.8 3.2 0.05 With more than 120 remaining surface, is protected wind, fine earth these options zero. The next factor influencing deflation. When it decreases, remains unprotected gusts increases, respectively, 1 t/ha perennial grasses field up 40–70 non-moldboard plowing 260–297 moldboard plowing. Conclusions. To reduce loss fertile deflation, recommended carry basic leaving crop residues which near prevent
