Objective of these investigations was assessment of surface and underground waters with nitrogen of a model landscape in the Oka river basin. Performed investigations showed that lands of agricultural use contribute to pollution of water bodies with biogens. Maximum content of ammonia nitrogen was observed in water of a small river in its area, located in the influence zone of dacha lots, where fertilizer application is not controlled. The greatest concentrations of nitrates, nitrites and ammonia nitrogen were observed in underground waters, being formed in the territory of dacha lots and irrigated lands. Reed, vegetating on banks of the small river, plays a certain role in processes for water self-purification, as it accumulates a significant amount of nitrates, but at the same time, faded remains of the plant are secondary pollutants for the water body. Data obtained can be used as a source material for ecological monitoring of small rivers in Ryazan region. To organize and to perform ecological audit in order to control correspondence of gardening associations' activity with environmental codes and to work out a complex of measures, correcting their activity. In order to prevent secondary pollution of water bodies of drainage area agrolandscapes, agricultural organizations should mow higher water plants along banks of drainage collectors by the end of vegetation season.
