20-year field experiment: Rotate corn for better soil health

Soil microbes are living, working barometers of soil health. They are responsible for turning atmospheric nitrogen into forms plants can use, and for releasing nitrogen back into the air. Farm management decisions undoubtedly ...

Radish cover crop traps nitrogen; mystery follows

When you think of a radish, you may think of the small, round, crunchy, red-and-white vegetable that is sliced into salads. You might be surprised to learn that a larger, longer form of this root vegetable is being used in ...

Nitrogen in the soil cleans the air

Eutrophication harms the environment in many ways. Unexpectedly, nitrogen fertilizer may also be positive for the environment. And even acidic soils, promoting the destruction of forests, can have a positive effect. Researchers ...

Microbes play important role in soil's nitrogen cycle

Under our feet, in the soil, is a wealth of microbial activity. Just like humans have different metabolisms and food choices, so do those microbes. In fact, microbes play an important role in making nutrients available to ...

Ozone, nitrogen change the way rising CO2 affects Earth's water

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked ...
