FIELD: agriculture.
SUBSTANCE: invention relates to agricultural machine building and may be used to treat soil. The device for meliorative soil treatment comprises a combined wedge-shaped stand, fertiliser tubes mounted on its rear part. In the lower part there are ploughshares installed with the help of a shoe in the stand opening. In front of the stand there is a vertical disc knife. A slot cutter is fixed to the combined wedge-shaped stand with a hole - a material duct for ameliorants. The slot cutter is deepened lower than the plane of ploughshare cutting by the value of placement of degraded soil layer. The value of slot cutter depth shall be closed to the value "a" of the surface treatment. In the deepened part of the slot cutter the hole-material duct has output holes, at the same time side holes are diverted back from the motion direction. The front cutting part of the slot cutter has facing with solid wear-resistant alloy. The depth of slot cutter treatment and the angle of inclination towards the horizon may be adjusted.
EFFECT: usage of this device increases soil fertility and crop capacity of crops in acid, saline, gypsified soils.
