Climate Change

A team from ARS and the University of Minnesota tested soil additives containing nitrogen-fixing microorganisms in a 3-year field study.

ARS, the University of Arkansas and the National Cattlemen’s Beef Association, led a study to identify environmental impacts from U.S. beef production.

An ARS research team along with the Southwest Climate Hub in Las Cruces, NM, developed a resource called The Water Adaptation Techniques Atlas.

Scientists have assembled a collection of yeasts that convert agriculture waste into bio-oil, which is then easily converted into biodiesel or renewable jet fuel.

ARS scientists are sounding out a new way to improve biogas production and help the environment.

Researchers have developed a new, easier way to find the answer to the question, "How much carbon is stored in soil?"

Scientists investigated practices that might help smallholder farmers increase sustainability of their lands and adapt to a changing climate.

Often viewed as pests, grasshoppers may have a larger environmental role to play.

ARS researchers have developed a unique mobile system that assesses and maps out soil carbon to a depth of 30 centimeters (the plow layer) – all in real time.

Intercropping perennial herbaceous crops with trees successfully increased organic soil carbon levels.

ARS helped the National Aeronautics and Space Administration with the launch of SMAP , a new satellite measuring the amount of water in top soil layers around the world.
