SU1613016A1 - Method of recliming solonetz and calcareous soils - Google Patents

Abstract

The invention relates to agriculture, in particular to agriculture. The aim of the invention is to increase fertility and reduce soil contamination. The exhaust gases of the aggregate performing the treatment of the soil are passed through an electrostatic field and a corona discharge in the zone of corona electrodes of the same sign; the electrodes of the opposite sign are located below the zone of movement of the gases. When this occurs, the additional oxidation of exhaust gases and the deposition of solid dust particles with contaminants sorbed on them. The exhaust gases are then introduced into the soil, moistened with sprayed water. At the same time strongly acidic products. After being dissolved in water, they enter the soil, and carbon dioxide remains in the surface air layer. The method allows to increase the fertilizing and meliorative effect of exhaust gases, to reduce their contaminant capacity. 1 il.

Description

The invention relates to agriculture and can be used in the treatment of carbonate and saline soils.

The aim of the invention is to increase fertility and reduce contamination.

SOILS;

The drawing shows a device for implementing the proposed method.

The device contains a tank 1 for water, a pump 2. an electric motor 3. a filter-ionizer 4, a tank 5 for absorbing solid impurities, corona electrodes 6. a perforated electrode 7. insulators 8. a high-voltage unit 9. pipelines 10, connecting hoses 11. distributors 12. frame 13 of a tillage unit, tubes 14, nozzle 15 for spraying water, working body 16 of a tillage implement.

During the processing of the soil, the exhaust gases of the tractor engine pass through the corona discharge zone, where the gaseous products are additionally oxidized. Soot particulate matter sorbed by the contaminant is charged in the area of the corona electrodes 6 and deposited by the perforated electrodes 7 into the container 5 to absorb solid impurities. The exhaust gases are brought to the surface of the soil at the moment of its loosening, being moistened simultaneously with sprayed water. Sulfur and nitrogen oxides dissolve in water droplets and increase its acidity; acids enter the soil with water. Carbon dioxide does not enter the soil, since it does not dissolve in acidified water, thus, its content in the soil air is excluded.

PRI me R. Has carried out pre-sowing cultivation of chestnut soil. The method implemented by the structure shown in the drawing. A tractor is equipped with a system for cleaning and additional oxidation of exhaust gases; a tractor is mounted on a cultivator.

ABOUT

introduction of gases into the soil and their moisture. The water tank is placed on the tractor. A voltage of 30 kV at a current of 18–20 mA was applied to the electrodes. The exhaust gases were released through the filter ionizer 4, where they were further oxidized in the zone of corona electrodes 6, and the precipitation of solid impurities by electroplating agents 7 into the container 5. The purified gases were applied to the soil surface at the time of loosening at the same time wetted with sprayed water. The application of the method led to an earlier emergence of seedlings.

In vegetative experiments, an increase in the yield of the green mass of the pea-pea mixture was obtained in comparison with the known method by 9–40%.

The method allows to significantly reduce the pollution of the soil and forest belts during the processing of fields, at the same time additional oxidation of exhaust gases leads to an increase in the reclamation and fertilizing effect of loose gases. Their application to the surface of loosened soil with simultaneous moistening allows to avoid an increase in the CO content in the soil air. To reduce air pollution, the use of a device with the system for introducing gases into the soil off is also advisable when moving between fields.
