(Texas A&M University, 1999)In order to optimize phytoremediation techniques, it is important to first understand the plant physiological processes associated with enhanced absorption and translocation of the target metal in the plant. The emphasis ...
-
(Texas A&M University, 1996)Many municipal water supplies in Southeast Texas have a relatively high level of Ne and low total dissolved solids. Smectitic clays which respond to wetting by swelling, especially when wetted with high Na waters of low ...

(Texas A&M University, 1996)The fate of agrochemicals in soils is governed by various transport, retention, and transformation processes. The herbicide pyrithiobac (sodium 2-chloro-6(4,6 dimethoxypyrimidin-2-ylthio) benzoate), developed by DuPont, ...

(Texas A&M University, 1995)Reduced tillage rice production can result in rice straw and other residue on the soil surface which may enhance NH, volatilization of surface-applied N. Laboratory, greenhouse, and field experiments were conducted to ...

(Texas A&M University, 1999)Carbon dioxide exchange rate (CER) is an indicator of an ecosystem's response to changing environmental conditions. Long-term measurements of CO₂ exchange between coastal wetlands and the atmosphere will improve our ...

(Texas A&M University, 1993)Chemicals may enter the environment in a number of ways accidents, spills during transport, leakage from waste disposal or storage sites, or discharge from industrial facilities. Hydrocarbons usually enter the environment ...
-
(Texas A&M University, 2001)Municipal solid waste landfills in the United States are built with a composite bottom liner consisting of a flexible membrane liner of high-density polyethylene overlying a compacted soil liner. Hydrocarbons have been ...
-
(Texas A&M University, 1998)A baseline survey of concentrations of Mn, Fe, Zn, Cu, Se, As, Cd, Cr, Co, Pb, Ba, and Ni was performed for 100 soils from seven Land Resource Areas of Texas. Nearly 300 soil samples from the upper, middle, and lower depths ...
-
(Texas A&M University, 1993)Cyclotriphosphate (C3P) is of interest to soil scientists because it demonstrates little or no retention by soil constituents. Non-sorption is desirable in the development of mobile P fertilizers. Work was expanded to ...
-
(Texas A&M University, 2002)Soils from a broad climogeographic region of the U.S., ranging from Alaska to Louisiana and Texas, were obtained from the NRCS National Soils Laboratory in Lincoln, Nebraska. Soils were also collected in the summer of ...
-
(Texas A&M University, 1999)The leaching of a Na⁺-affected calcareous soil with water results in two concurrent recesses: (i) CaCO₃ dissolution, and (ii) replacement of Na⁺ on the cation-exchange complex by Ca²⁺. In the current study, Woodward soil ...
