| Abstract: | The results of the study concerning the general biomass accumulated by grain crops (winter rye, spring barley, spring wheat, oat) are submitted in the article. It has been found out that the quantity of vegetative residue is directly dependent on the general efficiency of crops. Under the condition of crops efficiency equal to 40-50 cwt/ha. the mentioned quantity of vegetative residue is as follow: winter rye - 46,0-53,9 cwt/ha., barley -34,9-39,5 cwt/ha., spring wheat and oat - 38,3-44,0 cwt/ha. of dry substance. The degree of soil erosion and the layout of a slope where the crops are cultivated being are indirect influence on the weight of vegetative residue through changing crops efficiency, a prevailing formed by roots which constitute about 70-73% (with fluctuations from 69 up to 79%). |
