More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations. David...

Sustainable farming, initially adopted to preserve soil quality for future generations, may also play a role in maintaining a healthy climate, according to researchers at the Department of Energy's Oak Ridge and Los Alamos national laboratories. ORNL and LANL scientists are exploring the large potential of the earth's soils to sequester carbon, with estimates claiming that new land-use practices could greatly reduce U.S. carbon emissions by as much as 25 percent. But exactly which practices...

Researchers report in the Soil Science Society of America Journal that 3-D laser scanning can provide a more thorough analysis of a soil's quality, helping to further understand how healthy crops are produced. Soil researchers pay close attention to bulk density, as it is one of the most common soil measurements and it is often used as a measure of soil quality. A soil's bulk density can be indicative of the ease of root penetration, water movement, and soil strength. Measuring this...

Scientists Integrate Soil Science Data with Remote Sensing to Report Soil Carbon Flux Resulting from Land Management Changes.Changes in soil carbon occur with changes in land management. Scientists at Oak Ridge National Laboratory and The University of Tennessee investigated quantifying soil carbon changes over large regions. They integrated remote sensing products with a national carbon accounting framework in a project funded by the U.S. National Aeronautics and Space Administration, Office...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
