15N natural abundance technique does not reveal the presence of nitrogen from biological fixation in field grown carob (Ceratonia siliqua L.) trees
(International Society for Horticultural Science (ISHS), 2008)The presence in agroecosystems of plants able to develop symbiosis with nitrogen (N2) fixing microorganisms is encouraged as may decrease the need for mineral N fertilizers. Biological N2 fixation is widespread among ...
