Relevance of subsoil irrigation usage for growing feed crops on alluvial meadow soils is shown. Distribution of pjezometric pressure, along the water emitter line during the irrigating period, is analyzed. Formation of moisture patterns in the soil regarding the quantities of irrigating water and emitters design are considered. In order to define the characteristics of moisture patterns in the soil, depending on the quantities of irrigating water, the ratios of vertical water spreading Kv and forms Kf are calculated.
