The document discusses strategies for increasing nitrogen fixation through legumes to improve soil fertility for smallholder farmers in Africa. It outlines several potential solutions including various types of legume crops that can be used as green manures, fallows, forages, or grain crops. The key strategies proposed to increase nitrogen inputs from legumes are: increasing the area of land planted to legumes; improving legume productivity through better agronomy and use of phosphorus fertilizer; selecting better adapted legume varieties; using improved rhizobium strains and inoculating legume seeds; and linking legume production to new markets to increase demand. The document emphasizes testing technologies on-farm and involving farmers in evaluating what legume options best fit their
