The available water resources for irrigation of grassland located in different river catchments within the Kurpiowska Valley are very limited. As the additional transfer of water from Mazurian Lakes is not possible, it is necessary to use own water resources of hydrogenic soils with relatively high soil water retention by application of so-called “regulated outflow method”. Application of such a method requires reconstruction of drainage-subirrigation systems, its proper operation and maintenance.
