'Health cards' to find out the condition of agricultural ecosystems
In order to provide farmers and anyone else involved in managing agricultural ecosystems with a tool enabling them to assess the impact of their farming practices on the health of their crops and soils, the Basque Institute for Agricultural Research and Development NEIKER-Tecnalia has created its new TSEAs or 'Agricultural Ecosystem Health Cards.' These handbooks are an improved version of the cards created in the 1980s by the United States Department of Agriculture.
