(54) METHOD FOR PRELIMINARY PREPARATION

I

The invention relates to methods for preparing soil for planting or sowing agricultural crops and can be used in preparing land for forest nurseries and planting forest crops.

There is a method of preparing soil for cutting, which includes cutting (cleaving). stumps, combing tree roots from the soil at mutually perpendicular passages by passive working bodies. The extracted tree roots are formed into shafts with a time lag to drain the soil on the roots, followed by compression by heavy rollers, then raked to the burning site (1 |

The disadvantage of this method of combing tree roots is the partial removal of the humus layer, the reduction of the natural fertility of the soil; deterioration of its physical and mechanical properties. In addition, the arable horizon is not completely relieved of obstacles in the form of tree roots, the method of extracting tree roots from the soil is ineffective, the permeability of workers and tillage organs are not cut.

is provided; the soil is burned.

There is also a known method for tilling soil, according to which, after cutting out (stumping) stumps in the longitudinal direction in the soil monolith, narrow slits are milled, and then the soil monoliths with tree roots located between the gaps are destroyed.

With this method of treatment, tree roots prevent complete loosening of the soil monolith, which is free from the sides and over the top. Woven tree roots comb, form trees, squeak, compress and burn.

The monolith is subjected to loosening (exploding) with a reservoir turnover of 90 °. With such

5 processing vertically arranged tree roots acquire a horizontal position, then comb them out. To complete the tillage, it is necessary to make five passes (2).

The disadvantages of this method are similar to the disadvantages described above. Moreover, the method of deep loosening active working bodies is not naschel. distribution

Claims (1)

A method of preliminary preparation of the soil of felling, including milling of slits, deep loosening, characterized in that, in order to preserve the natural soil fertility, create conditions for patency of the working bodies of tillage machines, reduce energy consumption for chopping wood roots after cutting stumps in the longitudinal direction along the same direction slots are milled and horizontal layers are cut between them at half the working depth, then slots are milled in the transverse direction and the horizon is cut at the same time ial layers to the remaining processing depth.
