Now in its third edition, this classic textbook includes basic concepts and applications in agriculture, forestry, environmental science, and a new section entirely devoted to ecology. This revised and updated edition guides students through biochemical and microbial processes in soils and introduces them to microbial processes in water and sediments. Soil Microbiology, Ecology, and Biochemistry serves as an invaluable resource for students in biogeochemistry, soil microbiology, soil ecology, sustainable agriculture, and environmental amelioration.

Key Features


  • New section on Ecology integrated with biochemistry and microbiology
  • Sections on exciting new methodology such as tracers, molecular analysis and computers that will allow great advances in this field
  • Six new chapters: bioremediation, soil molecular biology, biodiversity, global climate change, basic physiology and ecological interpretations
  • Expanded with contributions from leading soil microbiologists and agronomists on both fundamental and applied aspects of the science
  • Full-color figures
  • Includes a website with figures for classroom presentation use


Undergraduate students in soil science, soil microbiology, agronomy, and related disciplines. Faculty, graduate students and researchers at institutions with strong programs and libraries at institutions with departmens in all these disciplines.

"This is a comprehensive text for the study of soil ecology. It covers the subject in sufficient depth for an advanced undergraduate or post graduate course in soil microbiology and biochemistry...the reader soon begins to relate the discussions to plant health and fruit development. The topics are covered to a depth that addresses a wide range of readers, from those who wish an overview of the subject to those who need to know the fundamental microbiology or biochemistry. The 18 chapters are divded into five broad subject areas, starting with background and continuing through the soil biota, interactions, biochemistry, and concluding with the impact of human processes. There is little current appreciation of the impact of cultivation on soil ecosystems, thus we employ few strategies to manage these systems to our advantage. A book like this is food for though." - Gary Strachan, in FRUIT GROWER
