FIELD: agriculture.
SUBSTANCE: invention relates to methods of mole drainage arrangement on drained agricultural lands. Method involves arrangement of mole drains across tubular drainage direction. Novelty is that on drained lands drain sections of tubular drainage with width from 6 to 8 depths of tubular drain are selected and at mole drainage arrangement within selected drain sections calcium carbonate fine powder at rate of 40-60 g/m is fed into mole drain cavity.
EFFECT: expanded operating performances of providing reduced intensity of tubular drainage oozing by 20 %.
