Özet

Biological nitrogen fixation (BNF) provides many functional benefits for agroecosystems. In
this study, we investigated BNF services by Rhizobium bacteria in agroecosystems and
developed a new framework for BNF services based on the modified MEA (Millennium
Ecosystem Assessment). In the new framework (BNF-MEA), all services, roles and benefits
related to BNF in agroecosystems were collected and classified. Data collated from around the
world indicate that BNF can play role in provision of 31 services/benefits as direct and indirect.
Based on BNF-MEA framework, services, goods and benefits divided into 4 sections. In the
BNF-MEA framework, we added new indicators to structure such as forage production, healthy
food, soil nitrogen amount, global carbon cycle, earthworms abundance, global nitrogen cycle,
soil health, photosynthesis, soil microbial activates, intercropping, soil biodiversity, carbon
sequestration, greenhouse gases emission, cover crop effect and fixation of atmospheric
nitrogen. These changes were based on the current conditions in the legumes agroecosystems.
