Worldwide Contrast in Application of Bio-Fertilizers for Sustainable Agriculture: Lessons for Sub-Saharan Africa

Abstract

The use of bio-fertilizers in sub-Saharan Africa (SSA) is low compared to selected developed and Asian countries. The later have perceived the products as useful and have invested in use of bio-fertilizers in their agricultural systems. Effective regulations in developed and selected Asian countries have enhanced the availability of high quality products. Conversely, lack of awareness, infrastructure, skill and absence of a supportive regulatory framework in SSA has negatively impacted the use of bio-fertilizers. This review aims at pointing out what SSA could learn from selected developed and Asian countries to improve the availability and adoption of high quality bio-fertilizers. The benefits in terms of biological nitrogen fixation, nutrient uptake, yield increases, cost saving, and utilization constraints are discussed to create awareness of stakeholders interested in the agricultural application of the technology in SSA.
