Method for improving the water-air regime of soil under perennial forage crops implemented as follows.

On irrigated land with crops or annual or perennial forage crops, second, third, etc. years of growth perpendicular to power the pipeline 1 and the direction of crops using Shelestov produce meats vodoplavujushih slots 2 and crotona 3 (Fig. 3). The walls of the slit 2 is formed by vertically cutting the arable layer 6 and the soil 7 and the seal wall by displacing the soil to the side of molehills 3. In the lower part 4 of the slit 2 a chisel working body form the loosened area. Displaced soil is placed in the side slit 2 and molehills 3. Eventually, the soil and the soil displaced by sealing walls obtained with the slit 2 a complex configuration, where the density is greatest near the soil lateral protrusions 8 of molehills 3. Simultaneously with cutting of the slits 2 and molehills 3 in it stack drain pipe 9, which is fed under pressure irrigation water. The diameter of molehills 3 exceeds the diameter of the drain pipe 9 in 7 - 10 times. This allows the drainage pipe 9 to slide freely in the cavity of molehills 3. The internal diameter of the drain pipe 9 is 3/4" or 1". The wall thickness of the drain pipe 9 is equal to 3 mm pipe Material 9 is highly structured porous polyethylene, capable of flowing freely through your wall of water molecules. Drain pipe 9 is placed on the mouth of the lower part 4 of the slit 2 in crotaline 3. This reduces the friction resistance when pulling the drain pipe 9 within molehills 3 (Fig. 3-6). In the implementation of irrigation plot orositeley pipe 9 water molecules gradually filled through the mouth of the lower part 4 of the slit 2, and then the cavity molehills 3.
