Adsorption of As(V), As(III) and methyl arsenic by calcite and the impact of some groundwater species
(2009-05-15)The objective of this research was to investigate the retention of arsenate (iAsV), arsenite (iAsIII), monomethyl arsenate (MMAsV) and dimethyl arsenate (DMAsV) by calcite and assess the impact of dissolved Ca2+, Mg2+, ... -
Bt vs. non-Bt corn (Zea mays L.) hybrids: effect on degradation of corn stover in soil
(2010-07-14)A billion tons per year of genetically modified corn residues are soil incorporated having both direct and indirect effects on the belowground environment, soil carbon (C) sequestration, and nutrient cycling. If Bt genetic ... -
Chloride Analysis of the Soils Overlaying the Carrizo-Wilcox Aquifer
(2013-09-28)With a vast amount of people living in semi-arid to arid environments around the globe, the resource of water is valued very highly. The Carrizo-Wilcox aquifer in SW Texas is a semi-arid zone and was chosen as the site for ... -

Effect of Municipal Treated Wastewater and Brackish Groundwater on the Water Holding Properties of a Clayey, Calcareous Soil
(2018-02-14)Wastewater reuse is a practice that has been gaining attention for the past few decades as the world’s population rises and water resources become scarce. This study compared the long-term (15+ years) effects and suitability ... -
Effect of Vertically Heterogeneous Soil on Simulated Water Storage and Surface Energy
(2017-06-28)The global effects of climate change and policy decisions are simulated, in part, by land surface models; yet, the models often use incomplete soil information that may result in unreliable estimates of soil water storage ... -

Management effects on labile organic carbon pools
(Texas A&M University, 2005-08-29)It is well documented that increases in soil organic matter (SOM) improve soil physical properties and increase the overall fertility and sustainability of the soil. Research in SOM storage has recently amplified following ... -
MICROBIAL RESPIRATION RESPONSE TO C, N, AND P AVAILABILITY IN LOBLOLLY PINE FOREST SOILS
(2011-05-05)The complex cycle of nutrients and organic matter in the soil is one of the planet‟s vital processes for maintaining life. Microscopic organisms, or soil microbes, fill a crucial role in this process, as they decompose ... -
Mineralogy Associated With Acid Mine Seepage as Determined Using Fourier Transform Infrared Spectroscopy and Relations to Acid Base Accounting
(2017-04-27)Over 7,000 km of streams in the eastern United States are negatively affected by acid drainage from coal mines (U.S. Environmental Protection Agency, 1994). Pyrite (FeS2) is known to be the primary cause of acid formation, ... -
Modeling Stacking Disorder in Soil Kaolinite
(2018-10-09)Kaolinite is ubiquitous in soils and is the dominant clay mineral in highly weathered soils such as Oxisols and Ultisols. The determinative roles of mineral structures at the atomic level in their surface properties, their ... -

Physicochemical Interactions of Source-Rocks with Injected Water-Based Fluids
(2015-04-27)Water-based fracturing fluids contain polymers to function either as fluid viscosifiers or friction-reduction agents. Whereas much work has been done on optimizing these functions, little or no published work focuses on ...
