Creator:: Keirstead, Heath
Abstract:: The mechanisms governing short- and long-term belowground carbon dynamics need to be understood. As part of a larger project developed to assess the effect of quantity and quality of litter inputs on the rate of soil organic matter (SOM) formation, I examined SOM in the H. J. Andrews Detritus Input...

Creator:: Brant, Justin B.
Abstract:: Most carbon (C) transformations in soil are carried out by a diverse and complex soil microbial community. The size and composition of the soil microbial community is determined by poorly understood interactions between the quantity and chemical composition of plant inputs, as well as climate. Given the metabolic diversity of...

Creator:: Crow, Susan E.
Abstract:: Soil organic matter (SOM) is the terrestrial biosphere's largest pool of organic carbon (C) and is an integral part of C cycling globally. Soil organic matter composition typically can be traced directly back to the type of detrital inputs; however, the stabilization of SOM results as a combination of chemical...

Creator:: Murphey, Virginia L. W.
Abstract:: There is a growing consensus that anthropogenic warming will impact soil organic matter (SOM). Globally, soil contains 2-3 times more carbon (C) than plants, and like plants, temperature induced change of SOM could have significant climate repercussions. Although, the majority of warming experiments have increased day and night temperatures equally,...

Creator:: McFarlane, Karis J., 1979-
Abstract:: Belowground carbon (C) storage and quality of soil organic matter (SOM) in forest soils have implications for sustainable forest management and C sequestration, but how these pools change in response to management is poorly understood. I investigated whether fertilization and competing vegetation control, applied alone or in combination early in...

Creator:: Robins, Colin R.
Abstract:: In unstable landscapes, modern pedological research explores the role of soils as products and indicators of geomorphologic change. Understanding the dynamics of hill slope pedogenesis is especially important in regions with limited, poor, or threatened soil resources. The island of Cyprus, situated in the eastern Mediterranean, is claimed by many...

Creator:: Stewart, Gregory B.
Abstract:: Dam removal is increasingly viewed as a river restoration tool because dams affect so many aspects of river hydrology, geomorphology, and ecology; but removal also has impacts. When a dam is removed, sediment accumulated over a dam’s lifetime may be transported downstream; and the timing, fate and consequences of this...

Creator:: Gale, Eric S.
Abstract:: In order to properly utilize organic amendments as nitrogen sources, reliable methods to estimate plant-available nitrogen (PAN) are needed. The objectives of this study were to (1) evaluate the use of crop and soil responses in fertilizer N equivalence (FNE) calculations, (2) examine the relationships between the C/N ratio, total...
