Description

The invention relates to the field of agricultural land reclamation.

The known method of land reclamation of soil Solontsovs, including plantation plowing, with the plantation plowing destroying a very dense solonets horizon, and calcium carbonates from the lower horizons moving to the surface.

However, this method is laborious.

There is also known a method of chemical melioration of solonets, including the introduction into the soil of gypsum, clay-gypsum, fbshogypsum and other calcium-containing substances that can fraudulently displace the calcium absorbed by the specified substance G 21.

The disadvantages of the known method are the limited raw material resources, the remoteness of their extraction from the place of use, the high cost of ameliorants and transportation to the place of application, as well as the need for thorough mixing with the soil.

The aim of the invention is to increase the fertility of the soil and increase the productivity of agricultural crops.

The goal is achieved by the fact that, as an ameliorant, the exhaust gases of the tractor engine are used, and plowing is carried out with the handicraft of well holes at the bottom of the boron truck, into which exhaust gases are fed with simultaneous rolling of the soil with copying seals.

The method is carried out in the following manner.

After selecting the site for tillage and preparation of the tractor unit to the exhaust pipe of the tractor, a heat-resistant hose is attached, the other end of which connects to the device, ensuring the distribution and supply of gas to the bottom rack of the delimiter. Plowing conducts 20 s with a well-recessed bottom of the furrow with simultaneous supply of exhaust gases when they are completely sealed. Hitting the loosened mass of solonetz and carbonate horizons with a large adsorption surface, carbon dioxide (the main component of the exhaust gases of a tractor engine) dissolves in the soil moisture, resulting in 30 portions of PPC.

Due to the hole dimples of the furrow bottom and simultaneous rolling of the soil with copying seals, the engine exhaust gases react for a longer time and with a much larger amount of loose soil. When this occurs, neutralization of all the harmful exhaust gas products occurs by sowing them with soil. In addition, plowing with this method helps to protect

soil from erosion, as the surface of the loosened soil increases due to well holes.

Studies have been carried out in vegetative vessels and field experiments in which barley was sown. -

Claims (1)

Claim The method of reclamation of solonetzic soils, which consists in the fact that, in order to increase soil fertility and increase the yield of agricultural crops, the tractor engine exhaust gases are used as a reclamation agent, and plowing is carried out by making hole pockets at the bottom of the furrow, into which supply the exhaust gases while rolling the soil with copying seals.
