How Good Are Indicator Bacteria at Predicting Pathogens in Recreational Water?
Indicator Bacteria Pathogens Recreational Water
2009/12/16
Bacteria commonly used to indicate health risks in recreational waters might not be so reliable after all. Pathogenic E. coli were pervasive in stream-water samples with low concentrations of fecal in...
Agronomy Society Comments on the Legacy of Norman Borlaug
Agronomy Society the Legacy of Norman Borlaug
2009/12/16
Known as the father of the “Green Revolution,” Borlaug has been commended for his contributions to agricultural science and his ability to influence political policy. He is one of only five people in ...

2009/12/16
Odor complaints related to animal production have increased during the past decade. Swine slurry stored in open storages is a source of airborne contaminants, including ammonia and odorous compounds. ...
Grassed waterways are placed in agricultural fields where runoff water tends to concentrate because they can substantially reduce soil erosion. Mapping techniques that help identify where erosion chan...
Soil scientists often face the dilemma of wishing to study soil in remote areas because they are ideal places to study soil formation and distribution under natural conditions, but mapping them requir...
Metal Immobilization using Plant and Poultry Waste Can Revive Soil Ecosystems
Metal Immobilization Plant and Poultry Waste Soil Ecosystems
2009/12/16
Shooting ranges are the major source of Pb contamination in Japan where over 600 sites are present mostly in remote locations. Remediation of Pb-contaminated soils in a shooting range is generally mor...
Calcium Helps Evaluate Soil's Ability to Retain Earth's Carbon
Calcium Soil's Ability Earth's Carbon
2009/12/16
Soils play a vital role in dealing with the environmental impacts of rising atmospheric carbon levels, primarily CO2, from natural and human activities. The Earth's carbon budget is a dynamic process....
Understanding temporal variability in crop yields has implications for sustainable crop production, particularly since greater fluxes in crop yields are projected with global climate change.
Nitrogen fertilizer is a key ingredient for growing a good corn crop. It is not unusual for a well-fertilized crop to yield more than twice as much as an unfertilized crop. But how much nitrogen shoul...
Volatile Dense Chemical Liquids in Groundwaters Can Produce Slowly Bubbling Gas Flow
Volatile Dense Chemical Liquids Groundwaters Bubbling Gas
2009/12/16
The successful cleanup of DNAPL-contaminated sites depends on our ability to understand the processes that transfer the contamination from the source of a spill to the surrounding groundwater. Until r...
Rainfall and Manure Application Timing Affect Organic Carbon Losses
Rainfall and Manure Application Organic Carbon
2009/12/16
Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage domin...
Ethanol Production Could Jeopardize Soil Productivity
Ethanol Production Soil Productivity
2009/12/16
There is growing interest in using crop residues as the feedstock of choice for the production of cellulosic-based ethanol because of the more favorable energy output relative to grain-based ethanol. ...

Pharmaceutical and Personal Care Product biosolids liquid municipal biosolids
2009/12/16
Pharmaceuticals and personal care products (PPCPs) carried in biosolids (i.e., treated sewage sludge) may reach surface waters or groundwater when these materials are applied as fertilizer to agricult...
Illinois Soil Nitrogen Test Measures Microbial Nitrogen
Illinois Soil Nitrogen Test Microbial Nitrogen
2009/12/16
The Illinois Soil Nitrogen Test (ISNT) was developed for this purpose, and involves estimation of gaseous ammonia liberated by heating the soil with strong alkali in a Mason jar. Several studies have ...
