Many agricultural and environmental technologies require large upfront investments in exchange for longer-term benefits. This time profile of costs and benefits may deter adoption, particularly in low-income settings characterized by information constraints,
limited cash on hand, and high discount rates. We test the importance of these barriers to the adoption of an agricultural technique that helps to reduce land degradation and restore soil fertility in Niger. We find little evidence that liquidity or credit constraints
deter adoption: instead, providing farmers with training increases the share of adopters by over 90 percentage points, despite a majority of farmers already being familiar with the technology.
