Acidic Deposition and Forest Soils Context and Case Studies of the Southeastern United States
Knowledge in the field of acidic deposition is expanding rapidly, and both ex perts and non-experts are challenged to keep up with the latest information. We designed our assessment to include both the basic foundation needed by non experts and the detailed information needed by experts. Our asses...
