Researchers investigate 'whole farm' approach to reduce dairy pollution
..., phosphorus itself never reaches toxic levels. At elevated levels, however, it can result in rapid algae growth. Runaway algae growth can result in fish kills through oxygen depletion and the production of phytotoxins. In light of these facts, the city of Waco, which gets most of its drinking water from the...Oceans more vulnerable to agricultural runoff than previously thought, study finds
...t concentrations in the oceans and sustains highly elevated rates of biological productivity." In the gulf, wind-driven upwellings regularly bring nitrogen and other nutrients from the seafloor to the surface, stimulating the rapid reproduction and growth of microscopic algae called phytoplankton.
