ISFM should enhance soil fertility and productivity by combining organic and inorganic soil amendments. We find that both extension-only and extension combined with video increase ISFM adoption and knowledge. We further find evidence for increased adoption of ISFM practices among farmers in treatment communities that do not actively participate in the extension activities. The additional video intervention shows a significant complementary effect for these non-actively involved farmers, in particular regarding the combined use of the practices on the same plot. A causal mediation analysis reveals that increases in knowledge explain part of the treatment effects on adoption.</p> The full abstract of the study, if available Links https://www.nber.org/papers/w26052 Links to any published papers and related discussions Authors * Affiliations Academic and other institutes that the authors of the study are members of Delivery partner Organisations involved in delivering the trial, if appropriate Year Year Year199419951996199719981999200020012002200320042005200620072008200920102011201220132014201520162017201820192020202120222023202420252026 Month MonthJanFebMarAprMayJunJulAugSepOctNovDec Day Day12345678910111213141516171819202122232425262728293031 Journal Journal publishing the study, if available Publication stage * Working Paper Published Ongoing Research Forthcoming Discussion Paper Research theme * Entrepreneurship Innovation Business Growth Country Country or countries where this study took place.
