  • Australian Growers directed to certified laboratories

    Grain growers are encouraged to make sure that the soil testing laboratory they use in coming months is certified to conduct the test they require. This is one of the messages contained in a new Grains Research and Development Corporation (GRDC) fact sheet Better Fertiliser Decisions for Crop Nutrition. Department of Agriculture and Food (DAFWA) researcher Ross Brennan said soil ...

  • Southern soils mitigate manure microbes

    That swine manure sprayed on to fields adds valuable nutrients to the soil is well known. But what is not known is whether all that manure is bringing harmful bacteria with it. A new study looks at the levels of nutrients and bacteria in soils of fields that have been sprayed with manure for fifteen years or more. The research team, composed of scientists from the USDA-ARS Crop Science Research ...

  • Satellites help map soil carbon flux

    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 of Earth Science. Results ...

  • Detailed soil information for Africa now available

    Zoom in on an African village, and see whether the soil is clayey or sandy, or how much nutrients or organic carbon it contains. This is now possible since ISRIC and partners have launched detailed freely accessible soil property maps for Africa. The maps, that can be explored in Google Earth, contain predictions of more than 20 soil properties at six standard depths at 250 meter ...

  • Research to restore the fertility of earth`s soils

    In keynote addresses at the FAO Workshop on Sustainable Agriculture in Riyadh, Saudi Arabia on April 28 and April 29, 2009, soil fertility experts from the Nutrition Security Institute, (NSI) a non-profit organization located in Bellevue, Washington, presented advances and understandings in biotic soil fertility as a proven solution to the serious problems facing global agriculture. Their dual ...

  • Microbe diet key to carbon dioxide release

    As microbes in the soil break down fallen plant matter, a diet 'balanced' in nutrients appears to help control soil fertility and the normal release of the greenhouse gas carbon dioxide into the atmosphere. When plants drop their leaves, stems and twigs, this organic matter slowly becomes part of the soil as a result of decomposition, which is facilitated by bacteria and other microbes. This ...
