FIELD: agriculture.
SUBSTANCE: method for reducing the incidence of spring rape plants with Alternaria on oil-contaminated gray forest soils involves eliminating excess acidity of oil-contaminated soil by liming with a dose of lime calculated by the value of hydrolytic acidity, inoculation with the biopreparation Baikal EM-1 and mechanical treatment of soil at different depths for intensive aeration of the oil-contaminated soil layer for two years every two weeks during the vegetation period according to the scheme: 1st treatment—5 cm, 2nd treatment—10 cm, 3rd treatment—15 cm, 4th treatment—20 cm, 5th treatment—25 cm, 6th treatment—20 cm, 7th treatment—15 cm, 8th treatment—10 cm, 9th treatment—5 cm.
EFFECT: invention makes it possible to reduce prevalence and development of Alternaria on spring rape, increasing yield of oilseeds.
