Biological nitrogen fixation in trees in agroecosystems: twenty years of biological nitrogen fixation research in Africa.
With the low input of fertilizers into African farming systems, it is necessary to harness biological nitrogen fixation to its fullest extent. The greatest potential, at least in the short term, lies in nitrogen fixation in grain and pasture legumes and in nitrogen-fixing trees. To maximise nitrogen...
