The Aragón Rural Development Program (PDR) in Spain is promoting the cultivation of the esparceta legume in dry arable lands through its agri-environmental measures. This crop is known for its environmental benefits, such as biodiversity enhancement and improvement of soil fertility through nitrogen fixation. It also serves as good fodder for cattle. The program encourages no grazing or work in May to protect steppe fauna and allows a single annual harvest in summer. The measure is easy to use and less expensive for farmers compared to annual crops, covering 340 single application files and paying out around 180,000 euros in the 2020 campaign.
