Abstract

This invention relates to agriculture. The aim of the invention is to accelerate the decomposition of wood residues. After grinding and burial of wood residues in the soil, the surface is seeded with nitrogen-fixing plants, and lupine is used as these plants. The root system of lupine has nodules saturated with nitrogen, which contributes to the creation of good conditions for the decomposition of wood.

Description

The invention relates to agricultural production, 9 particularly to land reclamation.

The purpose of the invention is the acceleration of the decomposition of wood residues.

During the development of land pastured by milling machines, for example, MTP-44A, which have cutting elements rigidly attached to the rotor, the shrub, low forest and root system on peat and mineral lands are crushed at a speed of 6-18 m / s. Deep milling of the soil along with a shrub, low forest, buried wood is reduced to one technological operation. Chopped wood enriches the soil with organic matter. Over the first three years, the buried wood is rotting in the soil, intensively absorbing nitrogen from the sky. It has been experimentally determined that cultivated agricultural crops sharply reduce the yield of crop oil at the same time, so that the land developed for cultivation becomes ineffective. Therefore, in the first year of development

zakustarenny zatel their sow lupins (determined by experiments).

The mechanism of the effect of lupins on the accelerated decomposition of wood is as follows. Having absorbed nitrogen from the air, due to its biological features, lupins rapidly develop and form a root system equipped with nodules saturated with nitrogen. In this case, a uniform distribution of nitrogen over the developed area is achieved through the root system, which contributes to the creation of good conditions during the decomposition of wood.

A sufficiently large amount of biological nitrogen in the soil created by lupins, accelerates the decomposition of wood. In addition, the yield of lupins themselves is not reduced. In this way, after the technological operation of shredding and embedding the wood residues in the soil, lupins are sown by seeding the seeds to a depth of 4 cm. The agricultural technique of sowing lupins is well known.

Experiments have shown that the fast-food lands processed by the proposed method are put into operation two to three years earlier and give the estimated yield in subsequent years.
