The area of the Kutno County is an important agricultural production area in the Lodzkie province in central Poland. The high quality of soil had contributed to the development of intense agriculture and thus to the conversion of the natural hydrogenic landscape (peatbogs and marshes). Only 5% of the county’s area reminded covered by forest. Land acquisition was based on the drainage of the area and regulation of rivers, followed but changes in the dynamics of water flow in the landscape. Intensive plant production resulted in water pollution, especially with nitrogen compounds. Nowadays the situation gets worse due to superimposed impact of climate change, namely frequencies and duration of both hydraulic and agricultural drought. Yield loss results in increased interest of farmers in water retention and improvement of its quality.
