Hawassa University to host international symposium on balancing soil nutrients
Land degradation worldwide costs an estimated US$10.6 trillion every year and presents a huge challenge to future global food security. In sub-Saharan Africa, including Ethiopia, soil nutrient-depletion is directly related, where fertilizer use and agricultural productivity rates are the lowest in the world. Many African countries use little or no potash fertilizers, which are crucial for balanced fertilization and sustainable cropping systems.
