Book Description
Excerpt from A Treatise on Rocks, Rock-Weathering and Soils In the work here presented the writer has endeavored to bring together in systematic form the results of several years' study of the phenomena attendant upon rock degeneration and soil formation. Although beginning with a discussion of rocks and rock-forming minerals, the work must be considered in no sense a petrology as this word is commonly used. What is here given relative to the origin, structure, and composition of rock masses is regarded as an essential introduction to the chapters on rock-weathering. The portion dealing with the structure and composition of the resultant materials is an essential corollary to these same chapters. It is believed that no apology is necessary for bringing out the present work. The origin, structure, and mineral composition of rocks, particularly the eruptive varieties, are matters which have of late received much attention. In fact, it is to these rocks that the petrologists have devoted their best efforts. Since the introduction of the microscope into petrographic work, there has, however, been very little time devoted to the study of rocks in a weathered condition. The chemists have made analyses, but have disregarded the physical and mineralogical nature of the material analyzed. Other workers have studied the physical properties of rocks decayed, - in the form of soils, - but have in their turn disregarded their mineral and chemical nature. The writer has aimed to bring together here such results obtained by these workers in divers fields as it is believed will be for the mutual benefit of all concerned. The state of comminution reached by rocks during the processes of long-continued, secular decay, and the amount of leaching such have undergone, are certainly of as much practical interest to the agriculturist as of theoretical interest to the geologist.

Book Description
Soil science is perhaps one of the oldest practical sciences, having been of concern to man probably from the time he progressed from a strictly preda tory life to one in which agriculture became important. In view of the anti quity of concern with the subject, it is perhaps surprising that it can be approached from a fresh viewpoint, as is done in this book. Because soil science is an applied science, it is not surprising that the approach is usually descriptive, rather than imaginative. For agriculturalists and other land users, perhaps the most important part of soil science is the description of soils and the capacities of such soils to maintain crops, and this is reflected by the fact that soil science is usually treated ima highly descriptive manner, with soil classification being one of the main efforts. The treatment of the subject from a geological point of view, with considerable emphasis on the evolution of soils and the reasons governing their composition and form, makes this a highly readable book. Books on soil science are timely, with present-day concern with such major problems as the pollution of our environment and the possibility of overreaching our capacity for producing food for an expanding population.

Book Description
Elements move through Earth's critical zone along interconnected pathways that are strongly influenced by fluctuations in water and energy. The biogeochemical cycling of elements is inextricably linked to changes in climate and ecological disturbances, both natural and man-made. Biogeochemical Cycles: Ecological Drivers and Environmental Impact examines the influences and effects of biogeochemical elemental cycles in different ecosystems in the critical zone. Volume highlights include: Impact of global change on the biogeochemical functioning of diverse ecosystems Biological drivers of soil, rock, and mineral weathering Natural elemental sources for improving sustainability of ecosystems Links between natural ecosystems and managed agricultural systems Non-carbon elemental cycles affected by climate change Subsystems particularly vulnerable to global change The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book from this Q&A with the Author.
