FIELD: agriculture.
SUBSTANCE: invention relates to the field of agriculture and land reclamation. In the method phosphogypsum is added to leached chernozem. Additionally, limestone-shell rock, apatite and molybdenum ore concentrate are added. At that, introduction of ameliorants is performed in fractional manner. Half dose of rocks and concentrate of molybdenum ore are added to the stubble. It’s dragged at depth of 10–12 cm with subsequent dump plowing to depth of 20–25 cm. Then, the second half of the dose of the ameliorant is added and repeated harrowing is carried out at depth of 10–12 cm, with the following ratio of components, t/ha: limestone-shell rock – 11.5–12.5; apatite – 2.5–3.5; phosphogypsum – 11.5–12.5; concentrate of molybdenum ore – 0.06–0.10.
EFFECT: method makes it possible to increase soil fertility and crop capacity.
