Calm Temperament Improves Reproductive Performances of Beef Cows

Whittier, W. D.; Kasimanickam, R.; Assay, M.; Schroeder, S.; Kasimanickam, V.; Gay, J.; Hall, J. (Virginia Tech. Powell River Project, 2015)

Profitability of a beef operation is determined by breeding season pregnancy rates and proportion of cows attaining pregnancy early in the breeding season. Many factors including temperament contribute to these reproductive ...

Characterizing Microbial Community Development in Reclaimed Mine Soils

Badgley, Brian D.; Sun, Shan (Virginia Tech. Powell River Project, 2014)

A significant amount of the research to date at the Powell River Project (PRP) has been focused on reforestation, with the assumption that tree growth will ultimately lead to the re-establishment of a fully functioning ...

Characterizing TDS Risk in Appalachian Landscapes: Techniques to Identify Mine Spoil TDS Generation Potentials

Johnson, Daniel K.; Daniels, W. Lee (Virginia Tech. Powell River Project, 2016)

Surface mining for coal in the Central Appalachians contributes total dissolved solids (TDS) to headwater streams, especially below larger mines and associated valley fills. The objective of this study was to characterize ...
