Smallholder farmers, particularly those in sub-Saharan Africa and South Asia, often lack access to soil testing laboratories to determine their soil’s fertility and the nutrients required to increase crop productivity. This causes farmers to apply fertilizer that may not meet their soil’s needs. One solution is the use of mobile soil testing kits that are inexpensive and easy to use.

IFDC evaluated the performance of three soil testing kits: Kasetsart, Hach, and SoilDoc. The goal was to identify kits that are accurate, affordable, portable, and user friendly. The analysis was funded by the United States Agency for International Development.
