Evaluation of the impacts of a soil fertility training project on farm productivity in the Volta region of Ghana Kwaw Andam, International Food Policy Research Institute, Accra, Ghana Simrin Makhija, International Food Policy Research Institute, Washington, DC, USA David Spielman, International Food Policy Research Institute, Washington, DC, USA Grantee Final Report Accepted by 3ie: January 2019 Note to readers This final impact evaluation grantee report has been submitted in partial fulfilment of the requirements of grant TW4.1022 awarded under Thematic Window 4. 3ie is making it available to the public in this final report version as it was received. During the course of this evaluation, the implementing agency changed their targeting strategy without informing the research team. This created a number of challenges for the analysis, including reducing the effective sample size. As a result, one cannot be very confident that the study was able to accurately measure the effects of the intervention.
