Abstract: Integrated soil fertility management (ISFM) technologies hold potential to protect against climate risks, reduce nutrient depletion and enhance food security. In this paper, we study how exposure to dry spells influences use and use intensity of ISFM technologies, specifically focusing on maize-legume intercropping and organic manure. We use a four-round panel dataset collected from households in six Malawi districts over a period of nine years and merged with daily rainfall data from the Department of Climate Change and Meteorological Services. The results using correlated random effects models reveal that exposure to one-year lag of late-season dry spells is associated with high likelihood of use and use intensity of organic manure and maize-legume intercropping. However, there is an inconsistent effect of two-year and three-year lags of both early-season and late-season dry spells on the use and use intensity of both technologies. We respectively attribute these positive and inconsistent impacts to farmers' perceived and delayed benefits of the technologies under dry spells. We recommend that promotion messages should properly package the technologies to include those with immediate and delayed but enduring effects and sensitize the farmers on the same.
