Soil Fertility book presents nine chapters written by renowned soil
fertility experts from Africa, Asia and South America. The book is divided into
two sections. Section 1, Biological Processes and Integration of Inorganic and
Organic Fertilizers for Soil Fertility Improvement, examines biological
processes that can enhance the soil fertility. The second section,
Improving Fertilizer Recommendation and Efficiency, looks at the
state-of-the-art in leaf sampling and analysis.
