This report presents the case of demonstration farms that operate within a cooperation network. The purpose of the study was to present the advisory opportunities in the process of linking education and the needs of farmers, with regard to innovative knowledge. In this process the advisory role was shown through the transfer of knowledge involving environmentally friendly practices from research and experiments conducted on demonstration farms. These farms implement many activities to limit the run-off of nitrogen and phosphorous compounds to groundwater, such as the preparation of fertilizer plans using innovative methods of balancing the fertilizer components, the application of intercropping and pro-environmentally friendly usage of organic fertilizers.
