  • Reining in soil’s nitrogen chemistry

    July 12, 2018

    American Society of Agronomy – Take a trip down into the soil beneath a field of crops. You won’t find just dirt, water, and creepy-crawlies. You’ll also find reactions that remind you of high school chemistry lab. Many researchers study the reactions of elements and compounds in the soil, especially because some, like nitrogen, are […]

  • Swapping crops to save water, and improve nutrition

    July 5, 2018

    Earth Institute/Columbia University – India will need to feed approximately 394 million more people by 2050, and that’s going to be a significant challenge. Nutrient deficiencies are already widespread in India today–30 percent or more are anemic–and many regions are chronically water-stressed. Making matters worse, evidence suggests that monsoons are delivering less rainfall than they […]

  • Flooding under development

    June 28, 2018

    We’ve all heard about how climate change might contribute to present and future floods along rivers and other watercourses, but a new University of Calgary modelling study suggests changes in land use and land cover along riverbanks could compound, not just add to, the problem. Babak Farjad, a post-doctoral fellow in geomatics at U of […]

  • How well does wheat weather heat waves?

    American Society of Agronomy – A heat wave sweeps through a city and people swelter, running indoors to find air conditioning. But crops out in a field aren’t so lucky. For them, there is no escape. Scientists in Australia are working to understand how heat waves impact wheat. They are mixing observational studies with techniques from […]

  • Warmer climate to dramatically increase volatility of corn crops

    June 14, 2018

    University of Washington – Corn, or maize, is the most widely grown crop in the world. Used in food, cooking oil, industrialized foods, livestock feed and even automobile fuel, the crop is one that both rich and poor people rely upon. Research led by the University of Washington looks at what climate change will mean […]

  • Try a little togetherness? Promoting cooperative weed management to curb herbicide resistance

    June 7, 2018

    University of Illinois College of Agricultural, Consumer and Environmental Sciences – In the fight against herbicide resistance, farmers are working with a shrinking toolkit. Waterhemp, a weedy nemesis of corn and soybean farmers, has developed resistance to multiple herbicide modes of action, often in the same plant. Even farmers using the latest recommendations for tank […]

  • Radish cover crop traps nitrogen, but where does it go?

    May 31, 2018

    American Society of Agronomy – When you think of a radish, you may think of the small, round, crunchy, red-and-white vegetable that is sliced into salads. You might be surprised to learn that a larger, longer form of this root vegetable is being used in agriculture as a cover crop. Cover crops are grown between […]

  • Long-term study shows crop rotation decreases greenhouse gas emissions

    May 24, 2018

    University of Illinois College of Agricultural, Consumer and Environmental Sciences– Many farmers grow corn and soybean in rotation to avoid the continuous corn yield penalty, but now there’s another reason to rotate. Scientists at the University of Illinois have provided further evidence that rotating crops increases yield and lowers greenhouse gas emissions compared to continuous […]

  • Climate change should help Midwest corn production

    May 17, 2018

    Michigan State University – Climate change and global warming put some forms of life at risk, but researchers found one instance that might not feel the heat – corn. Contrary to previous analyses, research published by Michigan State University shows that projected changes in temperature and humidity will not lead to greater water use in […]

  • Study could lead to better ways to combat crop-killing fungus

    May 10, 2018

    Rutgers University – About 21 million years ago, a fungus that causes a devastating disease in rice first became harmful to the food that nourishes roughly half the world’s population, according to an international study led by Rutgers University-New Brunswick scientists. The findings may help lead to different ways to fight or prevent crop and […]
