From the reviews:

„Concern for the environmental health of Amazonia is at the forefront of current international environmental issues. … Even more uncommonly discussed is the existence of ‘dark earths,’ the subject of this book. … Coverage ranges from a review of the literature to discussion of appropriate methodology. … the book is well written and an excellent resource on this topic. … it will be valuable for all academic libraries and useful to a wide range of readers in natural resources and even in anthropology. Summing Up: Recommended.“ (M. G. Messina, CHOICE, Vol. 42 (5), January, 2005)
