The N2Africa project aims to improve soil fertility and increase incomes for smallholder farmers in Africa by promoting legume cultivation and nitrogen fixation. It is a 4-year, $25 million project led by Wageningen University and involving research partners in 8 African countries. The project's goals are to raise legume yields by 954 kg/ha, increase biological nitrogen fixation by 46 kg/ha, and increase farmer incomes by $465, benefiting over 1 million people. It pursues these goals through developing better legume varieties and rhizobia strains, promoting their use with inoculants and fertilizers, and linking farmers to markets.
