The present invention relates to agriculture, namely the main treatment of the soil to a predetermined depth.

Widely known method of soil treatment using arable units, including the plough and tractor (khalanski V.M., Gorbachev IV "Agricultural machines". - M.: Colossus, 2005).

The disadvantages of this method are very energy intensive process, considerable intensity, energy intensity, long duration of treatment, and the use of additional tools (harrows, cultivators) for crumbling layers of the soil.

There is also known a method of tillage cutter (khalanski V.M., Gorbachev IV "Agricultural machines". - M.: Colossus, 2005), which prepare the soil for sowing in one pass across the field.

The disadvantage of this method is very energy intensive, the intensity, and hence the cost of tillage.

The objective of the invention is to reduce the number of machines for soil tillage, i.e. to exclude the use of tillage implements, to reduce tillage and ultimately reduce the cost of tillage by reducing the metal and accelerate soil.

This object is achieved in that the soil loosened and mixed air streams (jets), coming out of the pipes with holes laid on the ass is nnow depth all over the field, i.e. compressing the air in the pipe, it is possible to loosen all the field for several minutes or hours depending on the design of the device.

During the growing season, using this method, it is possible to aeration of the soil and subsoil watering and fertilizing the plants with liquid fertilizer.

The invention is illustrated in the drawing.

The drawing schematically shows a device for implementing this method. It consists of the manifold 1 is connected to the compressor 2 or water pump 3. For protection collector 2 is equipped with a safety valve 4. The collector is connected perforated pipe 5 by means of the knee 6, elbows and pipes provided with valves 7 and 8. Holes 9 tubes pointing up and to the side.

On fruit and vegetable station of the Russian state agrarian University - Moscow agricultural Academy named after K.A.Timiryazev., tried this method on crops dining carrot varieties "Nantes". The sowing was carried out on two plots with an area of 100 m2with loamy soil: one prototype, the second control. The control plot was prepared for planting in the traditional way. On the experimental plot at a depth of 30 cm 35 cm increments were stacked perforated pipe with a diameter of 20 mm and was conducted twice tillage before planting and 30 days after sowing. In the results on the experimental plot yield was 20% higher and the roots had a standard form, whereas the control plot received about 30% of the "tail-Enders" roots (roots with 3-5 "tails"), testified to the excessive density of the soil (due to compaction after treatment and the impossibility of loosening the soil under the plants during the growing season), resulting in lower output standard (commodity) roots.

Method of soil treatment, including loosening the soil to a predetermined depth, wherein loosening the soil carried out by the air streams created by a system of perforated pipes laid at a predetermined depth.

SUBSTANCE: invention relates to the field of agriculture. The method includes presowing treatment of soil, sowing and treatments between rows. At the same time presowing treatment is carried out for the depth of the assumed covering of seeds and is combined with sowing. Seeds are sown into the moist layer of soil onto the compacted bed for depth of 1-2 cm from the field surface level and are filled with loose and warm layer of soil moved from the surface between rows with its simultaneous mixing, forming a soil comb above sown seeds. Besides, height of soil combs is equal to the depth of seed covering specified by agrotechnical requirements reduced by 1-2 cm. Top and sides of the comb are compacted simultaneously with sowing, and soil combs are formed on the field surface in direction from the north to the south. During treatments between rows simultaneously with cutting of weeds and tillage of soil between rows of the cultivated crop, the upper layer of soil is shifted from the surface between rows into protective areas of a row of plants with simultaneous earthing up of crops. Thickness of filled layers of soil makes 2-4 cm and 6-8 cm during the first and second treatments between rows accordingly.
