Adopting fertilizer microdosing technology is associated with greater fertilizer use efficiency among cereal crop farmers in North Central, Nigeria. Analysis of farm-level data using Heckman and instrumental variable methods shows that a 1% increase in adoption of this technology corresponds to a 0.6% increase in efficiency, with similar elasticities for maize, sorghum, millet, and maize-sorghum. Adoption is more common among male farmers. The findings indicate that promoting fertilizer microdosing can reduce fertilizer waste and support climate-smart agriculture.
