FIELD: agriculture.
SUBSTANCE: invention relates to methods for para ploughing of drained agricultural lands. Novelty is that on drained lands near drained sections of tubular drainage are selected with width from 6.5 to 8.5 depths of tubular drains and at moment of splitter working passage within selected near drained sections fine powder of calcium carbonate at rate from 70-85 g/m is supplied to bottom of cavity of splitter blade passage trace. Splitter working passages are made across tubular drainage direction. Positive effect is achieved due to introduction of calcium carbonate fine powder to bottom of splitter blade trace passage cavity.
EFFECT: method enhances functional capabilities of analogue, providing reduced intensity of tubular drainage oozing by 20 %.
