The River Thames will fail to meet pollution standards in 2015 unless farmers use 20 per cent less fertiliser and water companies reduce phosphorus discharges from sewage treatment, according to a new study.

Scientists improve transgenic 'Enviropigs'

A research team at the University of Guelph has developed a new line of transgenic "Enviropigs." The new line of pigs is called the Cassie line, and it is known for passing genes on more reliably. The results of this project ...

Nitrate levels rising in northwestern Pacific ocean: study

Changes in the ratio of nitrate to phosphorus in the oceans off the coasts of Korea and Japan caused by atmospheric and riverine pollutants may influence the makeup of marine plants and influence marine ecology, according ...

Breeding soybeans for improved feed

Modifying soybean seed to increase phosphorus content can improve animal nutrition and reduce feed costs and nutrient pollution. However, further research is needed to commercialize this valuable technology. Knowledge of ...

Urban impacts on phosphorus in streams

Study probes sources of Mississippi River phosphorus

In their eagerness to cut nitrogen and phosphorus pollution in the Mississippi River and Gulf of Mexico, people have often sought simple explanations for the problem: too many large animal operations, for instance, or farmers ...

Helping feed the world without polluting its waters

(PhysOrg.com) -- A growing global population has lead to increasing demands for food. Farmers around the world rely, at least in part on phosphorus-based fertilizers in order to sustain and improve crop yields. But the overuse ...

Tracking phosphorus runoff from livestock manure

Nutrient runoff from livestock manure is a common source of agricultural pollution. Looking for an uncommon solution, a team of scientists has developed an application of rare earth elements to control and track runoff phosphorus ...
