Raising productivity of crop yields due to field protecting shelterbelts in Kherson region

Abstract

Certain negative signs such as erosion, deflation, and decline of crop capacity are typical for farmlands in Kherson region nowadays. All types of shelterbelts, which have been preserved in the Kherson region, were investigated. It was revealed that the forest belt blown, semi-wind-blown and solid construction can be found in approximately equal proportions. Taking to account that agro-climatic conditions of southern Ukraine are tight enough we have conducted analysis of statistical and own materials within the quality of performance by the forest belts of their function. To prevent dry winds and dust storms the non-blower belts were found to be the best, and for the best moisturising and increasing the yield of agricultural land the best ones are semi-wind-blown shelterbelts. We have researched that they condition even distribution of snow on the fields, lower rates of erosion and soil blowing, improve crop yields. Unfortunately, only 12–15% of shelterbelts in Kherson region is preserved in functional condition and can serve these purposes. The main factors of disappearance of protective afforestation are cutting of them, low moisturising and abandonment of forest belts.
