FIELD: agriculture.SUBSTANCE: method includes the application of fertilizing in the form of compost, consisting of organic and mineral components, pre-plant soil treatment and seeding. Meanwhile in the composition of the complex compost the organic components are half-fire-fang manure of the black cattle (BC), wheaten straw, wastes of animal feeding and grain treatment, sunflower peelings and raspings, and mineral components are phosphogypsum and leach, at the following interrelation of components (by mass %): phosphogypsum - 6-7, leach - 1-2, wheaten straw - 2-3, wastes of animal feeding - 2-3, wastes of grain treatment - 2-3, sunflower peelings - 2-3, raspings - 2-3, half-fire-fang manure of BC - rest, which are composted from the middle of April during 5 months, with monthly mixing by to ensure the aeration of composted heap until maturing. Then the obtained compost is brought into the soil in middle of September in a dose 70 t/ha with aftertreatment of soil to the depth 15-18 cm and sowing of winter wheat in the second decade of October.EFFECT: method allows to improve environment performance at the expense of decrease of NOinfiltration, Ndenitrification, improve soil properties, fertility, productivity of agricultural crop at continuation of the operation and aftereffect of the complex compost within 5 years, rational use of wastes of industry and agriculture.1 ex |
