Fertility needs in high-yielding corn production

Although advances in agronomy, breeding, and biotechnology have dramatically increased corn grain yields, soil test values indicate that producers may not be supplying optimal nutrient levels. Moreover, many current nutrient ...

Eyjafjallajokull's iron-rich ash fertilized North Atlantic Ocean

In about a third of the global ocean, the abundance of life is limited by a dearth of biologically available iron. The supply of iron to a region that is depleted in this important nutrient can stimulate algal productivity, ...

Poorer quality wheat when carbon dioxide levels in the air rise

Rising levels of atmospheric carbon dioxide have a negative impact on the protein content of wheat grain and thus its nutritional quality. This is the finding of researchers at the University of Gothenburg, Sweden, in a recently ...

Sea level controls carbon accumulation in the Everglades

How much carbon is stored in the organic soils of tropical wetlands is becoming an important question as erosion, agriculture, and global climate change slowly set into motion a series of processes that could potentially ...

The Everglades still threatened by excess nutrients

Since 1985, a state agency has constructed and continues to maintain hundreds of square kilometers of wetlands built to regulate the amount of nutrients reaching the Everglades in southern Florida. But this is proving to ...
