FIELD: agriculture, in particular, amelioration of mineralized soil grown up with stunted brushwood. ^ SUBSTANCE: method involves dressing sod while grinding bush and plowing-in wood remains under plow layer, with bush being bent at an angle to dressing direction before dressing of sod and with plowing-in of wood remains being performed in direction of bending of bush. Optimal angle of inclination of bush is determined as: alphaoa=alphaw-alphas, where alphaw is optimal angle of wood cutting; alphas is optimal angle of sod cutting. Apparatus has basic tractor and lifting working tool with two sections of disk batteries, with front section being mounted on frame hitched to tractor and rear section being pivotally joined with frame to be raised relative to it. Bending device is made in the form of shaft with pressing plate and positioned forward of tractor on individual frame for displacement in vertical plane. Moldboard is positioned perpendicular to optical bending direction. Width of moldboard is equal to width of front section of disk harrow. Pressing plate is positioned between tractor and front section of disk harrow on related frame. Width of pressing plate is at least equal to width of track between tractor caterpillars. ^ EFFECT: reduced consumption of power and high-quality preparing of soil in the process of development of bushy lands. ^ 2 dwg |
