  • Writing an equation for soil success

    Writing an equation for soil success

    Soil isn’t one size fits all. It may look the same under your feet – but under a microscope, that’s a different story. A plant’s roots, tiny bugs – these things can tell one soil from another quite easily. Soil ...

  • Soil moisture for crop health topic of symposium

    Soil moisture for crop health topic of symposium

    Soil moisture sensing through either contact or remote technology captures soil-plant-water information that relates closely with plant water availability and use. Innovations in remote sensing technologies can inform plant health assessments and ...

  • Counting carbon on the farm topic of symposium

    Counting carbon on the farm topic of symposium

    Agriculture is in the middle of the greenhouse gas (GHG) emission equation, as well as carbon storage. The soil is a potential sink for carbon though “carbon sequestration” in soils as well as agricultural biomass.  The ...

  • Keeping a pulse on the soil

    Keeping a pulse on the soil

    Leaving behind stubble is not ideal when shaving, but it’s a good practice to leave behind crop “stubble” after harvest. According to soil scientist Frank Larney, crop residue anchors the soil against wind and water erosion. ...

  • Bringing nitrogen out to pasture

    Bringing nitrogen out to pasture

    Cows in Brazil might start bellowing "leguuume" rather than "moo." That`s because Jose Dubeux Jr. wants to plant more legume trees in cow pastures. Dubeux is an assistant professor of Agronomy at North Florida Research & Education Center. ...

  • Food security may be increased by new agricultural production modeling

    Food security may be increased by new agricultural production modeling

    Farmers are used to optimizing crop production on their own lands. They do soil tests to choose the right amount of fertilizers to apply, and they sometimes plant row crops on some fields while keeping others in pasture. But is it possible to ...

  • Growing Sorghum for Biofuel

    Growing Sorghum for Biofuel

    Conversion of sorghum grass to ethanol has increased with the interest in renewable fuel sources. Researchers at Iowa State University examined 12 varieties of sorghum grass grown in single and double cropping systems. The experiment was designed to ...

  • Soil phosphorus in an organic cropping system

    Soil phosphorus in an organic cropping system

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. (For one overview discussion of phosphorus, see Phosphorus Famine: The Threat to Our Food Supply in the June 2009 Scientific American.) ...

  • Impacts of tillage on soil and crops

    Impacts of tillage on soil and crops

    The increasing popularity of reduced tillage on crops has not only been an important development in combating soil erosion, but it has also been associated with increasing organic material and producing high crop yields. For peanut crops, however, ...

  • Experiment demonstrates 110 years of sustainable agriculture

    Experiment demonstrates 110 years of sustainable agriculture

    A plot of land on the campus of Auburn University shows that 110 years of sustainable farming practices can produce similar cotton crops to those using other methods.  In 1896, Professor J.F. Duggar at the Agricultural and Mechanical College ...

  • Crop management: how small do we go?

    Crop management: how small do we go?

    The use of on-the-go crop and soil sensors has greatly increased the precision with which farmers can manage their crops. Recently released research in Agronomy Journal questions whether more precise management is necessarily more efficient. They ...

  • Self-seeding: an innovative management system

    Self-seeding: an innovative management system

    US researchers have investigated the potential for rye and wheat cover crops to perpetuate themselves, saving time and money for farmers while providing environmental benefits Winter cover crops provide important ecological functions that ...
