Nitrogen-fixing bacteria need oxygen, as they are aerobic. Farmers use natural fertilisers (eg farmyard manure, slurry, compost) or artificial fertilisers to replace nutrients lost when crops are ...
Wang said a likely next step in this research would be to determine how the flow of nitrogen into the ocean from human activity can impact the ocean’s nutrient cycle. “The key questions lie in our ...
The amount of nitrogen fertilizer needed to maximize the profitability of corn production in the Midwest has been increasing ...
Rivers, streams, lakes, and reservoirs aren't just scenic parts of our landscape—they're also vital engines for life on Earth ...
Nitrogen from urine forms a large part of this nutrient cycle but sloughed skin, placentas, and calf feces also aid in these inputs, which help sustain marine life. The study estimates that whales ...
A new study out of the University of Vermont quantifies just how much migrating female whales do to sustain ocean ecosystems.
The production of traditional fertilizers relies heavily on non-renewable energy sources such as natural gas, oil, and coal, ...
The reuse of human urine would allow for the production of sustainable fertilizers for urban agriculture, with significant environmental benefits, a new study concludes. The research evaluates the ...
