Food insecurity is a central concern and a fundamental challenge for human welfare and economic growth in Africa. Low agricultural production, results in low incomes, poor nutrition, vulnerability to risks and lack of empowerment. Land degradation and soil fertility depletion are considered the major threats to food security and natural resource conservation in sub-Saharan Africa (SSA). Investments in technology, policy and institutional reforms are needed to increase agricultural productivity to ensure food security and sustained national economies. Past research has generated numerous soil fertility management technologies which if adopted could propel the African continent out of the poverty trap. However, these technologies have had little, if any, impact due to low adoption by the smallholder farmers.

This book presents a comprehensive scientific overview of the components and processes that underpin the biological characteristics of soil fertility. It demonstrates the interdependence of soil biological fertility with physical and chemical characteristics of soil. The book highlights the enormous diversity of life in soil and the resulting effects that management of land can have on the contribution of this diverse community to soil fertility in an agricultural context. It is becoming more relevant to explore soil biological processes in terms of their contribution to soil fertility.
