Demand for alfalfa sowing to the water regime, the provision of soils with plant nutrients is considered. It has been established that the necessary levels of groundwater
(LGW) during its cultivation are largely determined by the granulometric composition of soils. It is shown that when it is grown on light soils underlain by sand, LGW should
be located at a depth of 0,6 m. A twofold increase in this indicator reduces the yield of dry mass of alfalfa by 26%. The causes of deterioration in the quality of grassy feeds
are given.
