Adding a charred biomass material called biochar to glacial soils can help reduce emissions of the greenhouse gases carbon dioxide and nitrous oxide, according to U.S. Department of Agriculture (USDA) scientists. Studies by scientists with USDA's Agricultural Research Service (ARS) are providing valuable information about how biochar-the charred biomass created from wood, plant material, and manure-interacts with soil and crops. As part of this effort, ARS scientists in St. Paul, Minn.,...

Scientists at the U.S. Department of Agriculture (USDA) are leading the way in learning more about "biochar," the charred biomass created from wood, other plant material, and manure. The studies by Agricultural Research Service (ARS) scientists at laboratories across the country support the USDA priorities of promoting international food security and responding to global climate change. ARS is USDA's chief intramural scientific research agency. Soil scientist Jeff Novak at the ARS...

Laura Jarboe pointed to a collection of test tubes in her Iowa State University laboratory. Some of the tubes looked like they were holding very weak coffee. That meant microorganisms "“ in this case, Shewanella bacteria "“ were growing and biochemically converting sugars into hydrocarbons, said Jarboe, an Iowa State assistant professor of chemical and biological engineering. Some of the sugars in those test tubes were produced by the fast pyrolysis of biomass. That's a...

A new study has found that an emerging tool for combating climate change may cause less harm to some soil animals than initial studies suggested. Earthworms perform many essential and beneficial functions in the soil ecosystem, including soil structure improvement and nutrient mineralization. However the earthworms' ability to perform these crucial functions can be suppressed when they are exposed to toxic substances. A Baylor University geology researcher, along with scientists from Rice...

New Zealand study shows biochar to decrease nitrous oxide emissions Nitrous oxide is a potent greenhouse gas and a precursor to compounds that contribute to the destruction of the ozone. Intensively managed, grazed pastures are responsible for an increase in nitrous oxide emissions from grazing animals' excrement. Biochar is potentially a mitigation option for reducing the world's elevated carbon dioxide emissions, since the embodied carbon can be sequestered in the soil. Biochar also has the...

By Don Comis, ARS Rain gardens are increasingly popular with homeowners and municipalities and are mandatory for many communities nationally. U.S. Department of Agriculture (USDA) scientists are finding ways to improve rain gardens so they not only reduce runoff, but also keep toxic metals out of storm drains. Rain gardens are plantings in depressions that catch stormwater runoff from sidewalks, parking lots, roads and roofs. Rain gardens come in various shapes and sizes, from large basins...
