The Influence Of Long-Term Anthropogenically-Induced Compaction On Select Properties Of Soils In The Midwestern United States, Eric C. Brevik
The Influence Of Long-Term Anthropogenically-Induced Compaction On Select Properties Of Soils In The Midwestern United States, Eric C. Brevik
Georgia Journal of Science
Soil compaction by heavy equipment has become one of the most important problems in modern large-scale plant production, but one area that has not received much attention is the effect of soil compaction on prairie soils over time periods in excess of about 10 years. This study addresses this issue by comparing properties in compacted to noncompacted soils in an abandoned farmyard and along a preserved stretch of the Mormon Trail. Properties compared include soil morphology, bulk density, carbon, C/N ratio, and apparent electrical conductivity (ECa). Bulk density, organic carbon, and ECa values were consistently different in …
Review Of "Roadside Geology Of Georgia" By Pamela J.W. Gore & William Witherspoon, Michael Roden
Review Of "Roadside Geology Of Georgia" By Pamela J.W. Gore & William Witherspoon, Michael Roden
Georgia Journal of Science
Pamela Gore (Professor of Geology at Georgia Perimeter College) and Bill Witherspoon (Fernbank Science Center Faculty) take the reader on a tour of geological sights in Georgia viewed from the numerous highways crossing the state. This book joins a series of Roadside Guides published by Mountain Press and is one of the best of the series. The book opens with an explanation of geologic time and plate tectonics. Amply illustrated, the book includes large-scale geologic maps as well as color images of various geological features. In the introduction the authors explain that Georgia is divided into several geographic divisions, Sea …
