Method for mole ploughing of lands being drained

FIELD: agriculture.

SUBSTANCE: on lands being drained, moles are cut across the direction of tubular drainage, tubular drainage sections close to drains, with a width of 4 to 6 depths of laying tubular drains, are allocated, and at the moment of cutting the moles, in the limits of the allocated sections close to drains, finely dispersed sulfur pyrite powder is dispensed into the cavity of mole drains, at a rate of 40 to 60 g/m. A positive effect is achieved due to introducing fine powder of sulfur pyrite into the cavity of the moles.

EFFECT: invention expands the functionality of the method, providing reducing the intensity of iron hydroxide sediment accumulation in the tubular drainage.

After summer deep tillage before planting herbs the levelling and compacting is carried out in a single pass with smooth water-filled rollers. Planting is carried out with a mixture of stand of grass growing naturally on sod-podzol sandy loam soils with band stripes. Overseeding of tall-stem cultivated crop of corn is carried out with simultaneous formation of the ridges between the bands, and inter-row processing is not carried out. The tall-stem cultivated crop of corn, which has not reached its complete ripeness, is left for winter. The harvesting is carried out on the second year in spring before the vegetation of grass with grinding and removal of the stems with leaves from the field for dry feed with the subsequent feed additive. In addition, overseeding grass between the band stripes is carried out into mechanically damaged ridges, and top dressing of grass is carried out, which is harvested during the complete vegetation season. The distance between the stripes is taken as 20-25 m, and the row spacing of corn is 70 cm.
