Food security in West Africa is challenged by complex issues, including rapid population growth, exploitation of nonrenewable resources, and chronic low soil fertility, but in this text experts from world agricultural institutions share their work to provide solutions. Topics covered include soil microorganisms and organic matter, indigenous knowledge, new cropping systems, use of nonorganic ...
The subsistence agriculture of the pre-chemical era efficiently sustained the nitrogen status of soils by maintaining a balance between N loss and N gain from biological nitrogen fixation (BNF): the microbial conversion of atmospheric N to a form usable by plants. This was possible with less intensive cropping, adaptation of rational crop rotations and intercropping schemes, and the use of ...
This volume covers recent developments in both fundamental and applied research in biological nitrogen fixation. It emphasizes the application of biological nitrogen fixation for sustainable agriculture, which should lead to poverty alleviation, environmental protection, and good agricultural practices generally. The roles of, and advances in, plant breeding, plant molecular biology, nodule ...
