Danish Study Examines Relationship between Soil Texture, Nutrient Leaching, and Waterway Contamination Research has documented the rise of nutrient runoff from flat agricultural fields with high rates of precipitation that adds nitrates and phosphates to waterways. These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of...

Uses more water, leaches less nitrogen In the search for the perfect crop for biofuel production, Miscanthus  has become the darling to many. But in an effort to not be charmed by its enormous potential for biomass production, researchers at the University of Illinois are taking a careful look at the pros and cons of its behavior in the field. A recent study analyzed water quantity and quality in plots of Miscanthus, switchgrass, corn, and soybeans and found that Miscanthus used...

A group of scientists uncover the nitrogen dynamics of a common urban landscape. Areas of turf-forming species created and maintained by humans for aesthetic and recreational (not grazing) purposes, i.e. "urban grasslands" are an extremely common, but poorly studied ecosystem type. There are over 150,000 km2of urban grasslands in the U.S. and many receive high rates of fertilizer, creating concerns about nutrient runoff to streams, lakes, and estuaries and emissions of greenhouse gases such...

Soil Salinity
2013-04-01 11:15:13

Soil salinity is the salt content within the soil; the process of increasing the content of salt is known as salination. Salt is a natural element of water and soils. Salination can be a result of natural processes such as the gradual withdrawal of an ocean or mineral weathering. It can be caused by artificial processes such as irrigation as well. Soils that are affected by salt are a result of excess accumulation of salts, normally most obvious at the surface of the soil. Salts can be...
