Boxing up ag field nitrogen

Spring in America's heartland is often wet. That makes its soil too soft for planting. One solution to that issue is tile drainage. Growers insert a series of pipes (drain tiles) under their fields, which drains water from ...

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 ...

Study sheds light on how plants get their nitrogen fix

Legumes are a widely consumed family of plants that serve as a significant source of dietary protein, fiber, and other essential nutrients. They obtain nitrogen through a specialized process known as nodulation, a symbiotic ...

Crops from no-till fields may need spring nitrogen boost

No-till crop production provides benefits through reduced soil erosion and soil moisture loss, which potentially increases yield. However, no-till fields with wheat stubble may need a nitrogen boost in the spring above that ...

Tracing nitrate in watersheds

Plants need nitrogen to grow, and nitrate is a common fertilizer ingredient, but high levels of nitrate contamination in drinking water sources can cause health problems. It is generally known that nitrogen flows through ...

A genetic alternative to fertilizer

Several studies have shown that a lack of nitrogen in soils adversely affects crop yields. The modern use of nitrogen fertilizers has improved yields to meet expanding global food demand, but in some cases up to 50% of the ...

Wood chips help curb nitrate leaching

(PhysOrg.com) -- Wood chips can significantly stem nitrate flow from crop fields into the surrounding watershed, according to a U.S. Department of Agriculture (USDA) study.

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 ...
