Application of micronutrients increases crop yields in sub-Saharan Africa

Micro- and secondary nutrient deficiencies are widespread in sub-Saharan Africa. Scientists Kihara et al. reviewed the responses of crops such as maize, sorghum, wheat and rice to micro- and secondary nutrient applications in this region. They showed that both single and combined nutrient applications increased yields in a majority of cases. They discuss the need for amending the actual fertilizer blends accordingly.
