FERTILIZER-MOISTURIZING IRRIGATING SYSTEM USING PREPARED WASTE WATER Russian patent published in 2019 - IPC A01G25/00 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture, namely to soil melioration, and can be used for drip and subsurface irrigation of various crops using waste water. Proposed system comprises main pipelines, subsoil and drip irrigation distributing pipelines, subsurface irrigation humidifiers, flexible irrigation drip irrigation pipelines. Distribution of liquid phase – water – is carried out via drip irrigation system (I). Distribution of solid phase – organo-mineral fertilizer – according to system of subsurface irrigation (II). Such distribution makes it possible to use irrigation technologies for different types of soils with account of irrigation norm within 600–6,000 m³/ha and norms of introduced organo-mineral fertilizers: nitrogen 20–100 kg/ha, phosphorus 20–120 kg/ha, potassium 20–100 kg/ha over the vegetation period.

EFFECT: continuous supply of irrigation water to the surface layer of soil, and fertilizers into the root layer.
