AI Insight

Researchers from the University of Illinois Urbana-Champaign investigated why smallholder farmers in Tanzania have low fertilizer adoption rates, identifying high turnover among local agro-dealers as a significant contributing factor. The study found that frequent changes in agricultural input sellers negatively impact farmer trust in product quality and disrupt normal market operations. This builds on existing knowledge that insufficient information and quality concerns are barriers to fertilizer use among sub-Saharan African farmers.


Understanding the relationship between agro-dealer stability and farmer trust can inform interventions to improve agricultural input markets in developing countries. Addressing dealer turnover could help increase fertilizer adoption rates and ultimately boost agricultural productivity among smallholder farmers in sub-Saharan Africa.

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.
