Soils: An Introductionby Michael J. Singer
Synopses & Reviews
Now in paperback, this book provides a fresh look at soil science. The goal is to help readers understand the parts that contribute to the whole soil individual and then appreciate how those parts function together. It begins by assembling the parts (solid, liquid and gas phases) of a soil, followed by explaining the interactions among the parts. Subsequently, genesis, classification, and interpretation of soil properties are explained. The “building the pedon” concept introduced in the first edition is continued in this latest edition. This edition also has a “western” perspective that emphasizes water management. For individuals whose careers involve environmental or land use management such as soil scientists, soil conservationists, forest soil scientists, environmental scientists, or geologists.
