This paper integrates traditional economic variables, soil properties, and variables on soil conservation technologies to estimate agricultural output among small-scale farmers in Kenya’s central highlands. The study finds that integrating traditional economics and soil science is invaluable, especially as omitting measures of soil capital can cause omitted-variable bias. The central policy implication is that while fertilizers are generally beneficial, their application is a complex art, and more is not necessarily better.
