How do nitrogen fertilizers affect soil microbial communities?
Apr 11, 2022 · However, the excessive use of chemical nitrogenous fertilizers has a negative impact on all the segments of the environment, namely soil, water, and air. Environment sustainability is at risk because of the loss of biodiversity in soil and water due to nitrogen pollution.

The struggle to provide, or “fix,” enough nitrogen in soil to grow bountiful crops has been a constant of human history. Both nitrogen and phosphorus are necessary components of photosynthesis; without enough, plants turn sickly and stunted. Nitrogen is naturally abundant, making up 80% of the atmosphere, but most plants can’t use it until it’s con...
Before the advent of synthetic fertilizers and fossil fuels, the movement of nitrogen through the biosphere was relatively stable. In what’s known as the “nitrogen cycle,” the element’s atoms traveled through flora and fauna, being released via excretion and death back into the ground, with some escaping through bacterial conversion to the atmosphe...
Across the planet, people whose livelihoods depend on lakes and oceans are bearing the brunt of the worsening crisis. For decades now, shrimpers who fish the Gulf of Mexico have borne the cost of one of the biggest marine “dead zones” in the world, with agricultural runoff traveling to the Gulf from the Midwest via the Mississippi River causing an ...
Sutton says a key problem blocking global action is what he calls “fragmentation” of efforts to address nitrogen pollution by policymakers. Agricultural runoff isn’t the only way that nitrogen is being pumped into the biosphere. It’s also released into the atmosphere as nitric oxide when fossil fuels are burned, and is also converted into another g...
As with the other planetary boundaries, policymakers have been slow to grasp the potentially catastrophic impacts of nitrogen and phosphorus pollution. Those who have begun to recognize the scale of the problem are finding there are few palatable approaches to it. As with fossil fuel companies, industrial agribusiness wields immense political and e...
In 2018, a group of scientists released a studyanalyzing satellite images for 71 of the world’s lakes. The results were consistent across regions: More than half showed evidence of algae blooms, and they were getting worse. The few lakes that showed signs of recovery were primarily those that had also experienced a reduction in atmospheric temperat...
Nov 9, 2020 · Nitrogen is essential for life on Earth but in excess, it is a dangerous pollutant and is poisoning water bodies, plants, animals and humans, while driving climate change through emissions of the potent greenhouse gas, nitrous oxide.
Jul 15, 2021 · Climate toll of fertilizers. One of the main nutrients that plants need to grow is nitrogen. But plants can’t take in nitrogen from the air the way they can absorb carbon dioxide or oxygen. In the early 1900s, scientists invented a process to mass-produce a nitrogen-containing compound, ammonia, that plants can absorb from the soil. Today ...
Feb 9, 2023 · The increasing production and use of nitrogen fertilizers exert extreme pressure on the environment. There are ways to mitigate its harmful impacts without sacrificing food quality and...
