Biochar is the carbonaceous residue produced from the pyrolytic conversion of biomass. It is generally used for agricultural applications as a soil amendment but has far wider potential. This book presents the use of biochar as a platform for the development of new intriguing solutions in several cutting-edge fields. The book is a useful reference volume for any reader with a strong scientific and technological background, ranging from scientific advisors in private companies to academic researchers promoting the spread of knowledge about biochar to anyone not already working with it.

This book contains 17 chapters providing details on decision tools that use linear programming to determine recommendations specific to a farmer's context intended to maximize profit from fertilizer use in sub-Saharan Africa. Chapter 1 and 2 discusses the principles and approach, and spatial analysis of fertilizer use optimization, respectively. Chapter 3 covers integrated soil fertility management in sub-Saharan Africa. Further, Chapters 4 to 16 explore optimizing fertilizer use within an integrated soil fertility management framework in countries in sub-Saharan Africa, including: Burkina Faso, Ethiopia, Ghana, Kenya, Mali, Malawi, Mozambique, Niger, Nigeria, Rwanda, Tanzania, Uganda, and Zambia. Finally, Chapter 17 describes the process of enabling fertilizer use optimization in sub-Saharan Africa.

Agricultural practices involving the excessive use of chemical fertilizers and pesticides pose major risks to the environment and to human health. The development and adoption of sustainable ecofriendly agricultural management to preserve and enhance the physical, chemical, and biological properties of soils and improve agroecosystem functions is a challenge for both scientists and farmers. The Special Issue entitled “Sustainable Agricultural Practices—Impact on Soil Quality and Plant Health” is a collection of 10 original contributions addressing the state of the art of sustainable agriculture and its positive impact on soil quality. The content of this Special Issue covers a wide range of topics, including the use of beneficial soil microbes, intercropping, organic farming and its effects on soil bacteria and nutrient stocks, application of plant-based nematicides and zeolite amendments, sustainability in CH4 emissions, and the effect of irrigation, fertilization, and environmental conditions as well as land suitability on crop production.
