An assessment of the impact of the anti-erosion complex on the productivity of cultivated crops has presented on the example of many years of experience in contour-ameliorative agriculture of the Kursk FARC located in the northern part rockfleece of the Medvensky district of the Kursk region.Two subtypes of chernozem represent the soil of the experiment: typical and leached.As anti-erosion measures, narrow-row stock-regulating poplar forest belts, reinforced by a simple hydraulic structure (ditch and rampart along the lower edge), have designed and planted along the contour at a distance of 216 m.

There are no anti-erosion measures in the control catchment.Analysis of long-term data showed a decrease in runoff and the absence of soil washout in the catchment area with a system of narrow-row forest belts 38 years after the experiment has laid in iphone 11 price edmonton comparison with the control.For the control catchment, a maximum soil washing of 22 t/ha recorded which significantly exceeds the permissible standards of flush.

A significant increase in crop productivity averaged 5.2 feed units.The profitability of growing crops in fields with forest belts exceeds the control by almost 50%.

The anti-erosion complex performs the task of strengthening the soil-protective role of the farming system.
