In Tanzania, using a low-cost soil test to pair field-specific recommendations with subsidy vouchers benefitted farmers significantly in both yields and profits when (1) fertilizer recommendations were calibrated to the needs of individual farms and (2) a subsidy made the recommended fertilizers affordable.
New AMA Innovation Lab research in Uganda on a program focusing on smallholder women farmers finds that the adoption of improved cultivation methods with minimal up-front costs had big impacts on village-wide food security and resilience.
This new study in Malawi showed that conservation agriculture adoption is most influenced by the adoption by neighbors, which could have implications for the overall cost of encouraging conservation agriculture across a region.
In a randomized controlled trial to study the impact of farmers’ knowledge about soil quality, we find that national-level fertilizer recommendations may be both unfit and excessively costly for many farmers.
Our results suggest that enforcement mechanisms can actually damage cooperative behavior as players shift from cooperative harvest strategies to more self-interested ones that lead to the collapse of the shared resource.
