sabreena relates to agriculture, in particular, to restore the productivity of perennial grasses.

Known techniques for selevinia of perennial grasses, where meleanie soil used in the system of care for the crops and to prevent erosion and accumulation of moisture in the soil.

For selevinia soil applied seleries-rotovating SN-2-140, without bringing raw soil PS-3-70, Ripper without bringing raw soil PMR-3,5, as well as a versatile Ripper function selevinia "RANCH" - patent # 2399177 from 20.09.10.

In addition to special Shelestov use knives-xelerate that are installed on the frame paticipating plough instead of the first and fifth corps and cut a slit depth of 30-35 cm at a distance of 1.4 m in the footsteps of the tractor. The number of cracks per 1 ha and depth depend on the characteristics of the site, on the steep slopes make deeper slots and more. Meleanie as agronomic method does not exert undue influence on the decimation of perennial grasses and does not eliminate the thickening foliage plants.

In GNU lower Volga research Institute of agriculture was developed and tested a new method of restoring the productivity of perennial grasses in the area of chestnut soils.

The technical result is achieved by the fact that in agrotechnical method of restoring the productivity of perennial grasses applied chizelevanie is in different variants of the arrangement of the working bodies (setting varies between racks is determined from the beginning of the continuous loosening of the soil [1] before the formation of the raw soil surface, equal to the width of one of the working body [2]. As a tool for deep processing used frame with built-in chisel it working bodies consisting of racks, each of which has a Shoe overlaid with a chisel. The working depth is set to 40 cm Process and quality indicators in the claimed bounds are optimal. Decreasing depth and increasing between racks is determined in the disposition of the working bodies reduces the efficiency of recovery of perennial grasses.

Thus, high efficiency recovery of perennial grass herbs is achieved due to the low energy non-selevinia soil.

The method of restoring the productivity of perennial grasses in the area of chestnut soils, characterized in that Kiselevka soil under perennial grasses produce working bodies established with different midplaza in the gap, providing the first solid loosening the soil before the emergence of the untreated soil surface equal to the width of one of the working body.
