Soil fertility and nutrient management are crucial factors in crop production; however, fertilizer adoption in Tanzania (and indeed Africa) remains below the recommended rate contributing to poor crop yields and poverty. This is partly due to farmers’ persistent suspicion that the quality of fertilizers in the market is sub-standard.
Journal of Development Economics found no reliable evidence to support farmers’ beliefs that the fertilizers available to them at local markets were of poor quality.

In our first Devil in the Details post, we sounded a cautionary note on fertilizer quality measurement, which can be hampered by pesky but crucial calibration problems that can yield misleading test results. Measuring quality matters because it helps to inform if perceptions of fertilizer quality among farmers are accurate. This, in turn, is critical to understanding drivers of low agricultural productivity associated with low utilization. Here, we shift our focus to seeds – another agricultural input that has similarly attracted the gaze of economists. Farmers are also widely concerned about seed quality but measuring seed quality (by farmers or researchers) is fraught with complexities in analysis and interpretation. At the end of this post, ....
