This study suggests key soil health indicators and examines the three-way interactions between mineral fertilizer, crop productivity, and soil health in Sub-Saharan Africa. It argues 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.
Abstract
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.
