The aim of this paperwork was the potential risk assessment from farming for natural-valuable ecosystems in Natura 2000 area, based on selected production and environment indicators. There were selected 75 farms located in Dąbrowy Krotoszyńskie (PLH300002) and in zone of direct effect on the NATURA 2000 area, in the Wielkopolska province. In the research data from years 2004–2011 were used. Dąbrowy Krotoszyńskie are located in two nitrogen vulnerable zone’s (NVZ) – Orla river, Czarna Woda and Kuroch rivers. Average size of 75 farms chosen to research was 37.8 ha. All of farms led plant and animal production. In the structure of livestock species predominated cattle (62.1%). Pork accounted for 36.6% share. To hear the current threat to the quality of surface waters from agricultural production for the 26 representative farms were calculated NPK nutrients balance by “on field surface” methodology. The results showed the average balance of nutrients surplus, the group analyzed on the level 121.9 kg N·ha–1 and 47.1 kg K·ha–1, which indicates that macro-components are unsustainable management. Content of phosphorus did not exceed standards. One of the basic environmental indicators in agriculture is a load of farmland nitrogen from manure produced by livestock kept on the farm. Of the 75 surveyed farms only 12% exceeded the recommended standard 170 kg N·ha–1, while in 56% of farms had amount not exceeding 100 kg N·ha–1. In the paper were analyzes the status and the needs for structures to store manure. From the 75 studied farms, only seven had the right size concrete structure for storing solid manure for a period of six months. As many farmers had a suitable tank for liquid manure. Concrete for solid manure did not have 18% of farmers and 73%, there was no tank for liquid manure. This demonstrates the high negligence in this area and the potential risk of migration of nutrients to the environment.

Zaproponowano podejście metodyczne do rozwiązywania niektórych problemów analizy transformacji i przemieszczania się wybranych zanieczyszczeń. Wskazano, jak dokonując analizy poszczególnych źródeł zanieczyszczeń i ich drogi do odbiornika, radzić sobie z brakiem danych, wykorzystując istniejące informacje statystyczne, dane pochodzące z katastru wodnego, a także jak dostępne dane dotyczące roku rozkładać na poszczególne miesiące. Metodykę zilustrowano przykładem dla wybranej zlewni.
