New soil sensor may improve efficiency of crop fertilization

Measuring temperature and nitrogen levels in soil is important for agriculture systems but detecting them apart from one another is difficult to do. Huanyu "Larry" Cheng, James L. Henderson, Jr. Memorial Associate Professor ...

Soil tainted by air pollution expels carbon

New UC Riverside research suggests nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere, where it can contribute to climate change.

How much greenhouse gas do tropical soils emit?

Nitrogen changes form as it cycles between air, soil, and life. Soils, for example, emit nitrogen either as inert dinitrogen (N2), which dominates our atmosphere, or as nitric oxide (NO) or nitrous oxide (N2O), the greenhouse ...

Letting farmland recover may let air quality recover, too

The USDA's Conservation Reserve Program (CRP) promotes sustainable agricultural practices to improve habitat, soil and water quality. It may have an unintended benefit of improving air quality, too, according to new research ...
