Abstract
Although many regions of the world have achieved dramatic increases in agri-
cultural productivity since the Green Revolution, staple cereal yields remain
low throughout sub-Saharan Africa (SSA). One important contributor to this low productivity is limited use of mineral fertilizer (Duflo, Kremer, and Rob-
inson 2008; Xu et al. 2009; Harou, Walker, and Barrett 2017; Harou et al.
2022). Researchers have studied a range of explanations for low investment
in mineral fertilizer, including unresponsive soils, high transaction costs, farm-
ers’ time preferences, nonadoption among peers, uncertainty, and absence of in-
formation about the suitability of fertilizer types and specific quantities for a far-
mer’s soils (Marenya and Barrett 2009; Duflo, Kremer, and Robinson 2011;
BenYishay and Mobarak 2018; Emerick and Dar 2021; Harou et al. 2022).1
