The paper presents research results regarding the influence of green manure on quality status of chernozem cambic from central Moldova and winter wheat harvest on this soil. Research has established that incorporation of two harvests of vetch green mass of 12.4 t/ha in the arable layer of chernozem cambic in the agricultural year 2015-2016 led to accumulation in the soil about 310 kg nitrogen; was synthesized about 3 t/ha of humus; was increased the labile organic matter content by 0.20% compared with witness variant; improved physical quality state of arable layer; formed a weak positive balance of organic matter and nitrogen in the soil. On the variant with application into the soil a harvest of green mass of vetch, the winter wheat harvest constituted 6.2 t/ha (growth rate 2.4 t/ha compared to control variant); on the plot with two harvests of green mass application - 7.0 t/ha (growth rate - 3.2 t/ha). Gluten content of wheat grains from variants with application of green fertilizers consists 28%, on the witness variant - 24%. Through the systematic use of green manure concomitantly with the phosphorus and potassium fertilizers in partial, the soil physical, chemical and biological quality state and agricultural productive capacity of soil can be restored gradually. In this content it is necessary to organize a system for green fertilizers use and create a seed basis of annual and perennial grasses for agricultural sector of Moldova
