FIELD: agriculture.
SUBSTANCE: invention relates to methods of drained agricultural lands deep tillage. Method involves making of cultivator working passages across tubular drainage. Novelty is that on drained lands drain sections of tubular drainage with width from 4 to 5 depths of tubular drains are determined and at moment of cultivator working pass within selected drain sections fine powder of calcium carbonate at rate of 45-70 g/m is fed into cavity of ploughshare cultivator passage trail.
EFFECT: method enhances analogue, providing reduced intensity of tubular drainage oozing by 21 %; positive effect is achieved due to introduction of calcium carbonate fine powder into cavity of ploughshare cultivator passage trail.
