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.

The paper presents results of analysis of the organizational and production changes occurring in Polish agriculture with concern of regions, and the assessment of potential effects of its influence on the environment with the use of standard agri-environmental indicators. The trends of changes in grounds exploitation, sown areas, animals stocking density and population, mineral fertilization, and gross nitrogen balance for Poland have been determined. The analysis included middle-term perspective of years 2000-2012. The changes occurring in particular regions have been compared in the period of time between 2002-2004 and 2010-2012. It has been established that existing natural factors, but mainly organizational and economic, significantly affect the changes occurring in agricultural sector leading to increasingly developing polarization, production specialization and concentration. The consequences of occurring processes are, regionally diversified, changes of standard agri-environmental indicators, implicating differential strength (pressure) of agricultural activity effects on the environment. The changes may have positive as well as negative consequences for the further working of the sector. There is an onward extensification of organization and agricultural production in the south-eastern provinces. The provinces’ levels of macro components consumption in mineral fertilizers, as well as animals stocking density in livestock buildings, are often twofold. There is an extensification of organization with simultaneous increase in its intensity in livestock production. The consequence of the organization extensification and its simultaneous increase is extension of environmental pressure on the areas of high concentration of livestock production (the Kuyavia-Pomerania, the Łódź and the Wielkopolska provinces) prominent in unbeneficial changes of agri-environmental indicators (e.g. nitrogen balance) resulting in i.a. deterioration in the quality of surface and ground water.
