No soil left behind: How a cost-effective technology can enrich poor fields

Source: Science Daily

Many farmers across sub-Saharan Africa try to coax crops out of sandy soils that are not ideal for holding water and nutrients. Traditional approaches would have them apply more fertilizers and use irrigation, but both require access to resources and infrastructure that many do not have. A relatively new technology modeled for eight African countries, and currently being tested in Zimbabwe, shows potential for improving harvests through increased water retention and accumulation of organic material.
