摘要

Soil health is the capacity to support the production of food, feed, and fiber while delivering other essential ecosystem services. We suggest key soil health indicators and examine the three-way interactions between mineral fertilizer, crop productivity, and soil health. Given the long history of soil nutrient depletion in Sub-Saharan Africa, we conclude that mineral fertilizer use, as a core component of integrated soil fertility management, must increase and be co-applied with organic inputs to increase productivity and fertilizer use efficiency and restore and sustain soil health.
