FIELD: agriculture.
SUBSTANCE: method involves cutting surface layer of soil and forming narrow slits to 60-70 cm depth; during slitting, forming water-accumulating channels of different depth and supplying water therein at flow rate of 5-25 l/s; on expiration of 2-3 days, providing digging and extracting rootages. Apparatus has frame mounted on supporting wheels and provided with vertical knives. One knife is positioned in mid portion of frame. Two other knives are positioned at ends of additional beams. Each of vertical knives is made flat, with concave curvilinear cutting edge and chisel at lower end. Soil deforming device with gauged heads is positioned at rear cut of knives. Heads are communicated with pull-type vessel via channels formed in knives bodies and via flexible hoses. Water is supplied from vessel via gauged heads into vertical channels and water-accumulating channels. During 2-3 days water moistens and softens soil to allow simplified extraction of rootages.
EFFECT: increased efficiency in extracting of plant rootages with minimal mechanical damage thereto.
