Une nouvelle \u00e9tude de l\u2019Universit\u00e9 d\u2019Arizona du Nord (NAU) et de l\u2019Universit\u00e9 de Californie (Berkeley), publi\u00e9e dans la revue Proceedings of the National Academy of Sciences<\/em>, a r\u00e9v\u00e9l\u00e9 un processus naturel de production de nutriments avec des applications potentielles r\u00e9volutionnaires pour l\u2019agriculture.<\/p>\n\n\n\n

Les chercheurs ont d\u00e9couvert que la diatom\u00e9e Epithemia<\/em> et des bact\u00e9ries fixatrices d\u2019azote appel\u00e9es diazoplastes<\/em> travaillent ensemble pour convertir l\u2019azote atmosph\u00e9rique en nutriments disponibles pour les plantes.<\/p>\n\n\n\n

Ce syst\u00e8me symbiotique fournit jusqu\u2019\u00e0 90 % de l\u2019azote utilis\u00e9 par les \u00e9cosyst\u00e8mes de la rivi\u00e8re Eel en Californie, n\u00e9cessaires au renouvellement des populations de saumons.<\/p>\n\n\n\n

Ce m\u00e9canisme, pr\u00e9sent dans les \u00e9cosyst\u00e8mes aquatiques du monde entier, pourrait conduire \u00e0 d\u00e9carboner l\u2019agriculture en rempla\u00e7ant les engrais azot\u00e9s actuels.<\/p>\n\n\n\n

Les scientifiques soulignent que l'exploitation de ces partenariats \u00e9cologiques pourrait \u00eatre essentielle pour d\u00e9carboner l'agriculture tout en maintenant la productivit\u00e9 et en soutenant la biodiversit\u00e9.<\/p>","protected":false},"excerpt":{"rendered":"
