FIELD: agriculture.
SUBSTANCE: inventions relate to the field of agriculture. The composition contains limestone-shell rock, apatite, phosphogypsum, molybdenum ore concentrate and additionally contains manganese ore concentrate in the following ratio, in t/ha: limestone-shell rock 11.5-12.5, apatite 2.5-3.5, phosphogypsum 11.5-12.5, manganese ore concentrate 0.13-0.17, molybdenum ore concentrate 0.06-0.1. In the method, the composition is applied fractionally. Half of the dose of the composition is applied to stubble, harrowed to a depth of 10-12 cm, followed by dump plowing to a depth of 20-25 cm, then the second half of the dose of the composition is applied and repeated harrowing is carried out to a depth of 10-12 cm.
EFFECT: inventions provide an increase in the fertility of leached chernozem and the yield of agricultural crops.
