Phosphorus (P) is both an essential nutrient in agricultural fields and a contributor to poor water quality in surface waters. To encourage improved P management in fields, the P Index was proposed as a risk assessment tool in 1992. After 20 years of use, modifications, and growing pains, does the P Index accurately assess the risk of P loss? A special section being published next month in the Journal of Environmental Quality addresses that question. The collection of papers grew out of a...

U.S. Department of Agriculture (USDA) research confirms that the time-tested practice of amending crop soils with manure also can help restore soils on damaged post-mining landscapes. Thousands of acres of land with little or no vegetation, once mined for lead and zinc, remain throughout an area of southwestern Missouri, southeastern Kansas, and northeastern Oklahoma. The mining activities also left behind a legacy of lead-contaminated acidic soils, toxic smelter sites, and large...

Findings have implications for brake pads, copper mines Minute amounts of copper from brake linings and mining operations can affect salmon to where they are easily eaten by predators, says a Washington State University researcher. Jenifer McIntyre found the metal affects salmon's sense of smell so much that they won't detect a compound that ordinarily alerts them to be still and wary. "A copper-exposed fish is not getting the information it needs to make good decisions," says McIntyre,...

Scientists from the Smithsonian and colleagues have found that waterbird communities can be the "canary in the coal mine" when it comes to detecting the health of urban estuary ecosystems. Their research revealed that the types of waterbirds that inhabit urban estuaries are influenced not only by urban development, but also by a far more natural process“•rain. The team's findings are published in the scientific journal PLoS ONE. The scientists compared waterbird communities in...

There is potential to store large volumes of Australia´s precious fresh water underground, to offset climate change, avoid evaporation losses and meet national water needs into the future, leading water scientists say. Following a major national scientific workshop in Canberra last week, researchers in the National Centre for Groundwater Research and Training (NCGRT) say that managed aquifer recharge — the injection or infiltration of excess surface water into underground...

Erosion
2013-04-01 12:48:39

Erosion is the process by which rock and soil are taken from the surface of the Earth by exogenetic processes like wind or the flow of water, and then transported and deposited in another location. While erosion is a natural process, human activities have increased by 10 to 40 times the rate at which erosion is happening globally. Excessive erosion results in problems such as desertification, decreases in agricultural productivity because of land degradation, sedimentation of waterways,...

The water cycle (or hydrologic cycle) describes the continuous movement of water above, below, and on the planet. Since the water cycle is in fact a "cycle", there is no beginning or end. Water exists in three states: liquid, vapor, and ice. Although the balance of water on our planet is fairly constant, individual water molecules may come and go. The water cycle is driven by the sun. The sun heats the oceans and allows water to evaporate into the air. The sun also heats snow and ice which...
