  • A Rare-Earth Approach to Tracing Soil Erosion
    . With rare-earth elements, we can use five or six tracers on the same field and tell precisely where certain soil eroded from.". Nearing emphasizes that none of the tracers currently used presents any risk to the environment or to the user. Sediment from a watershed in Coshocton, Ohio, collects
  • Soil Secrets Probed
    While technician Nancy Nubel checks temperature and humidity, plant physiologist Tom Kaspar measures the height of oat plants on one of the large soil columns in the upper level of the NSTL controlled environment rhizotron. Massive, state-of-the-art rhizotrons help solve the mysteries
  • Slowing the Flow: Grass Hedges To Catch Runaway Soil
    engineer at the Hydraulic Engineering Research Laboratory in Stillwater, Oklahoma. "This reduces sediment delivery to the stream and river system." Temple, working with ARS. Slowing the Flow: Grass Hedges To Catch Runaway Soil. Share/Bookmark Printable Version E-mail this page. Search News & Events
  • Precise Inputs for a Cleaner Environment
    reaching groundwater, says Dale A. Bucks, ARS national program leader for water quality management. But the emphasis soon expanded to include nitrates in surface water and groundwater and pesticides in surface water. "Now the program also emphasizes phosphorus and collects data on air quality, soil
  • Wire Splicing and Sealing Technique for Soil Mositure Sensors (.pdf)
    Employing a durable wire splicing technique is very important when considering the harsh environments the connection must withstand. Strong connections that are sealed from moisture are more likely to resist failure due to corrosion, electrical shorts, or broken wire connections. The procedure
  • Keeping Metal Machines And The Environment Clean
    are much too expensive. Thermal vacuum cleaning removes oils but leaves other forms of dirt and soil behind. And mechanical cleaning blasts parts with a medium such as dry-ice pellets, starches, or pressurized gas. Blasting is good for some applications, but it risks harm to the part and calls
  • Application Notes: Minncare(R) Cold Sterilant - Sporicide Concentrate For Surface Disinfection in Pharmaceutical Cleanroom Environments (.pdf)
    , remove heavy soil and gross filth from the surfaces to be disinfected. 2. Dilute Minncare Cold Sterilant with purified water to a 1% solution (100X dilution). 3. Apply the solution using a plastic spray bottle. 4. Al ow the solution to remain on the surface for 10 minutes and let air dry or rinse
  • Slashing Greenhouse Gases From Hog Waste
    treatment system (background) used on a 6,000-head swine farm in North Carolina. (D794-1). In 2004, ARS soil scientists in South Carolina and colleagues introduced an innovative hog-waste management system that may greatly benefit swine producers and the environment alike. Now these researchers have
