Marine ecosystems suffer from nutrient pollution, as most of our waste tends to get dumped in the sea. This kind of pollution can become very deadly, as high levels of nutrients foster algal blooms which destroy water quality and deplete its oxygen — in short, they kill everything else around them. New research at the
Surrounded by some of the world’s richest soil and home to two major grain processing plants, Decatur has long been a hub for agribusiness in the United States. One major trade-off comes in the form of excess nutrients, specifically nitrogen and phosphorus, that runoff from fertilizers used on local farm fields and from discharges from
Phosphorus-enriched soil is very much essential for agricultural purposes. But the current alarming fact is, this nutrient is increasingly being lost from soils all around the world. This mineral is one of the vital factors for the world’s food production and there isn’t an unlimited supply of this from the soil. Phosphorus in the soil
Hartbeespoort Dam in South Africa has a new invasive aquatic weed to battle, Salvinia minima. The proliferation of common salvinia, just as water hyacinth came under biological control through the combined efforts is no coincidence. In areas that experience high levels of nutrient inflow (pollution), the control of one aquatic weed opens resources to other
Florida’s tropical waters are home to a great diversity of life, but perhaps the most endearing is the Manatee. The manatee is a grazing animal and spends between six and eight hours a day feeding on seagrasses and other freshwater vegetation. The manatee actually plays an important role in controlling the aquatic plant growth in
Blue-green algae, technically known as cyanobacteria, are microscopic organisms that are naturally present in lakes and streams. Typically present at low number, blue-green algae can quickly become abundant in warm, shallow, undisturbed surface water rich in nutrients like phosphorous and nitrogen. Some blue-green algae produce toxins that could pose a health risk to people and
