英语. In course of the research there was studied the influence of fertilizer system on nutrients income with straw of legumes and grain legumes in sod-podzolic sandy loam soil. The research was realized in the conditions of the Republic of Belarus. As a result of realized research there were revealed that depending on the level of mineral nutrition with straw of winter crops in sod-podzolic sandy loam soil intake 25.2-49.7 kg/ha of organic matter, 9-36 kg/ha of nitrogen, 8-20 kg/ha of phosphorus and 51-102 kg/ha of potassium, straw legumes – 15.8-of 22.4 kg/ha of organic matter, 12-26 kg/ha of nitrogen, 8-13 kg/ha of phosphorus and 34-52 kg/ha of potassium. Return of the nutrients to the soil with 10 centners of straw of spring crops was as follows: nitrogen – 4.5-5.3 kg/ha, phosphorus - 4.5-5.2, potassium – 13.2-16.1 kg/ha, 10 centners of straw legumes - nitrogen - 6.9-8.2 kg/ha, phosphorus - 4.4 - 4.6, potassium – 16.6-18.0 kg/ha, 10 centners of straw of winter grain crops - nitrogen – 4.1-4.9 kg/ha, phosphorus - 2.6-3.1, potassium – 15.3-17.7 kg/ha.
