      abstract = {Small farmers in Sub-Saharan Africa exhibit low adoption  rates for mineral fertilizers. A promising hypothesis  explaining these puzzlingly low rates remains untested: a  perception among farmers that fertilizer in the market has  been compromised in ways that raise concerns about its  effectiveness. Information about fertilizer quality  problems is anecdotal rather than backed by reliable  evidence. A challenge: little research to date has focused  on understanding the relationships between input supply  chains and product quality. To achieve a clearer  understanding of this problem, this research links results  from tests of the quality of 661 samples of fertilizers for  sale in the markets of the Morogoro Region of Tanzania with  data from a survey of the region’s 225 input dealers.  Fertilizer nutrient and moisture content tests are  performed on the same samples in multiple laboratories  located in East Africa and in the United States. Results  from our research provide the first assessments of  market-available fertilizer quality in the region, as well  as the first analysis of relationships between fertilizer  quality and mineral fertilizer supplier characteristics.},
