Smallholder farmers in sub-Saharan Africa adopt agricultural inputs, including fertilizer, at low rates, contributing to low agricultural productivity. Previous research has shown that insufficient information and distrust in the quality of products for sale in local markets are among the reasons for low rates of fertilizer adoption and application. In a new study published in the American Journal of Agricultural Economics, University of Illinois Urbana-Champaign researchers examined the agricultural marketplace in Tanzania, finding that frequent turnover among local agro-dealers affects farmer perceptions of product quality and has implications for broader market functioning.
