Languages of publication
The project „The evaluation of environment condition in areas vulnerable to nitrogen pollution in Wielkopolska” was implemented within Institute of Plant Protection-National Research Institute and Wielkopolska Agricultural Advisory Centre in Poznań cooperation. The project was subsidized by Regional Fund for Environmental Protection and Water Management in Poznań. The aim of the analysis was to evaluate a certain number of environment components such as biodiversity and phytosanitary condition indicators. The analysis was conducted on chosen farms in areas vulnerable to nitrogen pollution in Wielkopolska. The farms area ranged from 10 to over 30 ha. On each farm one or two crops were fully analysed. All biodiversity factors were high or medium. Pests and diseases, which may cause a critical threat to monocultures and simplified rotation, occurrence was examined. It was concluded that infestation level of examined crops was not epidemic. The high quantity of beneficial and predatory insects balanced pests quantity. Different species and groups of weeds were found on each crop.
