Managing Soil Health for Sustainable Agriculture (Vol.I and Vol. II)
There has been growing concern that both intensive agriculture in the developed world and rapid expansion of crop cultivation in developing countries is damaging the health of soils which are the foundation of farming. At the same time we are discovering much more about how complex soils are as living biological systems. This volume reviews the latest research on soil monitoring and management.
Volume 1: Fundamentals (Burleigh Dodds Series in Agricultural Science, Band 48) starts by reviewing soil classification, sampling and ways of monitoring soil dynamics.
Volume 2: Monitoring and management (Burleigh Dodds Series in Agricultural Science, Band 49) surveys key techniques for managing soil, from irrigation and fertiliser use to crop rotations, intercropping and cover crops.
The final part of the book discusses ways of supporting smallholders in maintaining soil health in regions such as Africa, Asia and South America.

Drylands cover 40% of the global terrestrial space and are home for 2 billion people, often the most vulnerable. Land use is dominated by rangelands and much less by croplands, while barren areas with sparse vegetation mixed with rock outcrops are widespread. In spite of their hostile nature, drylands host 50% of global livestock and 30% of all present grown crops originate from them. This chapter addresses critical research issues needed to maintain soil health in the drylands, including nutrient cycling, preservation of soil biota, carbon sequestration, erosion control, rainwater harvesting and irrigation efficiency. The chapter examines the options for improving dryland soil health and provides a case study from Egypt, as well as looking ahead to future trends in this area and suggesting detailed further reading on the topic.
