Optical Assessment of Dissolved Organic Carbon
Natural organic matter is present in all sources of drinking water. When chlorine is used for drinking-water treatment, a portion of the natural organic matter reacts to form halogenated compounds, referred to as disinfection by-products (DBPs), ...

`How will Climate Change Affect Agriculture?
Agriculture and climate change are inextricably linked—crop yield, biodiversity, and water use, as well as soil health are directly affected by a changing climate. Climate change, which is largely a result of burning fossil fuels, is already ...

Evaluation of NASA satellite- and model-derived weather data for simulation of maize yield potential in China
Use of crop models is frequently constrained by lack of the required weather data. This paper evaluates satellite-based solar radiation and model-derived air temperature (maximum temperature, Tmax; minimum temperature, Tmin) from NASA and their ...

Nitrogen source and rate influence on tall fescue quality and nitrate leaching in a southern California lawn
In California, residential lawn area is second in planted acreage to production agriculture. Due to the demand for visually attractive lawns, relatively large amounts of N are often applied. The objective of this research was to investigate the ...

Drought stress responses and recovery of Texas x Kentucky hybrids and Kentucky bluegrass genotypes in temperate climate conditions
Turf quality (TQ) decline due to drought is a major concern in cool-season turfgrass management. The study was conducted to examine whether selected Texas (TBG) x Kentucky bluegrass (KBG) hybrids (HBGs) (Poa arachnifera Torr. x P. pratensis L.) ...

Productivity, oil content, and composition of two spearmint species in Mississippi
‘Scotch’ (Mentha x gracilis Sole) and ‘Native’ (Mentha spicata L.) spearmints are grown in the northern United States, but have not been evaluated in the Southeast. Two-year field studies were conducted in Mississippi at two locations (Verona and ...

Remote sensing of soil degradation: Introduction
In the 21st century, mapping and monitoring the occurrence of soil degradation will be an important component of successful land management. Remote sensing, with its unique ability to measure across space and time, will be an increasingly ...

Remote sensing and geographic information system for appraisal of salt-affected soils in India
Received for publication January 23, 2009. Quantification of the nature, extent, and spatial distribution of salt-affected soils (SAS) for India and the world is essential for planning and implementing reclamation programs in a timely and ...

Salinity monitoring in western Australia using remotely sensed and other spatial data
Received for publication January 27, 2009. The southwest of Western Australia is affected by dryland salinity that results in the loss of previously productive agricultural land, damage to buildings, roads, and other infrastructure, decline in ...
-
A methodology to estimate the future extent of dryland salinity in the southwest of western Australia
Received for publication January 27, 2009. In the southwestern agricultural region of Western Australia, the clearing of the original perennial vegetation for annual vegetation-based dryland agriculture has lead to rising saline groundwater levels. ...

Remote sensing of land degradation: experiences from Latin America and the Caribbean
Received for publication April 6, 2009. Land degradation caused by deforestation, overgrazing, and inappropriate irrigation practices affects about 16% of Latin America and the Caribbean (LAC). This paper addresses issues related to the application ...

Radar remote sensing of wind-driven land degradation processes in northeastern Patagonia
Received for publication February 27, 2009. Wind-driven land degradation negatively impacts on rangeland production and infrastructure in the Valdes Peninsula, northeastern Patagonia. The Valdes Peninsula has the most noticeable dunefields of the ...
-
Lag time in water quality response to best management practices: a review
Received for publication March 20, 2009. Nonpoint source (NPS) watershed projects often fail to meet expectations for water quality improvement because of lag time, the time elapsed between adoption of management changes and the detection of ...
-
Simplified method for quantifying theoretical underestimation of chamber-based trace gas fluxes
Received for publication June 19, 2009. Closed chambers used to measure soil-atmosphere exchange of trace gases including nitrous oxide (N2O) and carbon dioxide (CO2) generate errors due to suppression of the gas concentration gradient at the ...
-
Soil carbon dynamics and carbon budget of newly reconstructed tall-grass prairies in south central Iowa
Received for publication February 16, 2009. In addition to their aesthetic and environmental qualities, reconstructed prairies can act as C sinks and potentially offset rising atmospheric CO2 concentration. The objective of this study was to ...
-
Identification of Naegleria fowleri in warm ground water aquifers
Received for publication February 16, 2009. The free-living amoeba Naegleria fowleri was identified as the etiological agent of primary amoebic meningoencephalitis that caused the deaths of two children in Peoria, Arizona, in autumn of 2002. It was ...

Trends and transformation of nutrients and pesticides in a coastal plain aquifer system, United States
Received for publication March 19, 2009. Four local-scale sites in areas with similar corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] agriculture were studied to determine the effects of different hydrogeologic settings of the Northern ...

Dynamic factor analysis for estimating ground water arsenic trends
Received for publication March 14, 2009. Drinking ground water containing high arsenic (As) concentrations has been associated with blackfoot disease and the occurrence of cancer along the southwestern coast of Taiwan. As a result, 28 ground water ...
-
Spatially distributed lateral nitrate transport at the catchment scale
Received for publication January 23, 2009. In river catchments, N transformation and storage processes during lateral transport are important in controlling N loads of surface waters. There is a lack of approaches which capture lateral flows and ...
-
A watershed-scale assessment of cost-effectiveness of sediment abatement with flow diversion terraces
Received for publication May 1, 2009. Soil conservation beneficial management practices (BMPs) are effective at controlling soil loss from farmlands and minimizing water pollution in agricultural watersheds. However, costs associated with ...
