Changes in anti-deflation resistance of chernozem typical under different tillage and fertilizers

The scale wind erosion is increasing in Ukraine connection with the arid climate and intensive agricultural land use. Deflation causes significant damage not only to soil cover, but also environment. Research showed that resistance of soils deflation depended on their structural state. aim present study was establish influence different tillage systems fertilizers agrophysical parameters soil. According method dry sieving according Savvinov, content particles larger than 1 mm number agronomically valuable per 1% humus by V. Medvedev were determined research conducted a stationary experiment M. K. Shikula Department Soil Science Conservation Separated subdivision NULeS “Oleksandr Muzychenko Velykosnytinske Educational Farm” Fastiv district Kyiv region. experimental site chernozem typical. It found variant application straw, green manure mineral for reduced tillage, highest amounted 75.1-77.5%. provided deflation-resistant surface, as over greater 60%. Reduced together fertilizer "Straw 1.2 t / ha + N12 N78P68K68" creates best conditions aggregation layer 0-30 cm On non-plowing more favorable N78P68K68". plowing, indicators state typical deteriorated
