    Sustainability of agricultural systems is a major global concern due to population growth and a number of environmental factors. This book addresses the key to the development of sustainable agriculture-management of soil fertility. Combining data from temperate and tropical regions, it presents a complete picture of how various soils can best be managed under widely different environmental conditions.
    Soil Fertility Management for Sustainable Agriculture is an excellent reference for environmental and agricultural professionals as well as a textbook for undergraduate and graduate students preparing for a career in agriculture or soil fertility management.
