The Spanish Society of Nitrogen Fixation (SEFIN) has the following two major objectives: to gain deeper insight into the process of biological nitrogen fixation and the beneficial interactions between plants and microorganisms, thus contributing to improve sustainable agriculture and environmental protection; and to promote the organization of scientific meetings, to facilitate the exchange of ideas between professionals interested in agricultural development and between other national or international organizations with similar or complementary goals.
Currently, SEFIN has more than 100 members with expertise in the fields of microbiology, plant physiology, chemistry, biochemistry, and agronomy. The members belong to more than thirty research groups from universities and private and public research institutions.
Since its foundation in 1983, SEFIN has organized biennial national meetings, and since 2008 it has organized the Spanish-Portuguese conference, also on nitrogen fixation. Moreover, SEFIN contributed actively to organize the First US-Spain Program Development Workshop on Nitrogen Fixation (Granada, 1985), the V European Nitrogen Fixation Conference (Sevilla, 2000), the XI European Nitrogen Fixation Conference (Tenerife, 2014), and the first and second editions of the Iberoamerican Conference of Microorganism–Plant–Environment Interactions (IBEMPA) (La Habana, 2009; Sevilla, 2013).
Since 2004, SEFIN has belonged to the Confederation of Spanish Scientific Societies (COSCE), which includes over 80 societies and 40,000 scientists.
