FIELD: agriculture.
SUBSTANCE: invention relates to means of chiseling of drained agricultural lands. On drained lands across tubular drainage is working passages chisel type are made. Novelty is that on drained lands near drained sections of tubular drainage are selected with width of 5.5-7.5 depths of tubular drains and at moment of working passage of chisel within selected near drained sections fine powder of calcium carbonate in rate from 65 to 85 g/m is fed into cavity of chisel tip passage trace. Positive effect is achieved due to introduction into cavity of chisel tip passage trace of calcium carbonate fine powder.
EFFECT: expanded operating performances of providing reduced intensity of tubular drainage oozing by 20 %.
