These proceedings of the Soil Fertility Research Network (Soil Fert Net) Results and Planning Workshop bring together forty papers on soil fertility research for maize-based farming systems in Malawi, Zimbabwe and beyond. They represent over four years of work by members of Soil Fert Net and their associated institutions, and include results from our first Network Trials. The presentations generated much debate and this is recorded in discussion sessions. A panel of advisors produced an assessment of our work. We end the proceedings with reports from four planning sessions that helped to update and tighten the work priorities of our network for the future.312 pages
