A new report authored by researchers from the University of Nebraska-Lincoln suggests that the use of inorganic nitrogen and phosphorus for fertilization improves crop yields, but can have negative impacts on soil quality, the American Society of Agronomy has reported .
A study of crop lands in western Kansas has shown that inorganic fertilization increases organic carbon stocks while damaging soil’s structural quality.
Researchers collected soil samples from experimental fields fertilized with various amounts of inorganic fertilizers to determine how different nutrient levels might impact soil quality. The results showed that applying nitrogen and phosphorus at high rates can expedite soil erosion and cause other structural issues.Read More
A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek.
As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow.
Much of the original property and surrounding land has fallen prey to urban sprawl.Read More
Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die.
Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn.
This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area.
“‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters.
This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.Read More
