Turak O. The influence of leguminous-cereal mixtures on the fertility and antierosional resistance of soddy podzolic eroded soil of the Western Pre-Carpathians

Subject of research - the process of legume-grass mixtures antierosion efficiency formation, their effect on soddy podzolic eroded soil fertility indices. The aim - to establish the antierosion efficiency of natural and sown grass stands of mowing use on soddy podzolic eroded soils of the western Precarpatians. The research methods are field, laboratory, cartografic, comparative-computational, economic-mathematical. The antierosion efficiency of perennial legume-grass stands and changes of agrochemical and water-phisical soil fertility indices in the process of grassing and conducting soil-protecting crop rotation are determined. The technologies of legume-grass mixture development are worked out for grassing of eroded soils what secures the increase of antierosion resistance and extended reproduction of the soil fertility. The reserch results are introduced at the farms of the Kolomyya and Tysmenytsya districts of the Ivano-Frankivsk region over an area 60 ha yarly during 2006-2008. The field of application - the agricultural production.
