FIELD: agriculture.
SUBSTANCE: method of chiselling drained lands refers to the field of agriculture, and specifically to reclamation. Due to the suppression of vital activity of iron bacteria, the method reduces the intensity of tubular drainage ochretization, the deposition of iron oxide in drains. In the method of chiselling drained lands, pre-drained sections of tubular drainage are delineated for a width of 4.5 to 6.5 depths of tubular drains, working passages up to 45 cm deep are made with chisel across the direction of the tubular drainage, and at the time of the working passage of chisels, fine powder of copper pyrite with a particle size in the range from 0.03 to 0.07 mm in the norm from 55 to 75 g/m are fed into cavity trace of the passage of the chisel tip. The technical result consists in obtaining by the land user a durable and reliable closed drainage that provides the design mode of soil moisture during its use for at least its standard service life.
EFFECT: suppressing the vital activity of iron bacteria and reducing the intensity of tubular drainage ochretization.
