The effect of mineral and organic nutrient input on yields and nitrogen balances in western Kenya

The aim of this study was to investigate the effects of farm management practices (e.g., fertilizer and legume rotations) on grain yields and nitrogen balances in smallholder maize farms in East Africa. To test these hypotheses, we surveyed farmers participating in the Sauri Millennium Village Project, where agroforestry and rotational legume technology and trainings have been promoted since the early 1990s and where fertilizer subsidy programs were promoted from 2005 to 2008.
