The problem

What we found in the field.

Smallholder farmers in Kambia report buying bags of fertilizer that yield far below the printed nutrient claim. Counterfeit and diluted product enters the supply chain at the border and again at district markets. The economic damage compounds: a failed planting season costs both the input and the harvest.

A trustable verification rail, low-friction enough for a feature-phone buyer, could materially shift purchasing behavior. A scratch-off code, USSD lookup, or chemical test strip — the right answer is unknown; the field research is in the kit.
