  • Squeezing more crop out of each drop of water

    Studies in China and Colorado by Agricultural Research Service (ARS) scientists and cooperators have revealed some interesting tactics on how to irrigate with limited water, based on a crop’s critical growth stages. Laj Ahuja, research leader at the ARS Agricultural Systems Research Unit in Fort Collins, Colo., and colleagues conducted the studies. As one example, with wheat in China, they found ...

  • Manure Science Review Slated Aug. 12: How to Maximize Crop Benefits, Minimize Water Risks

    Manure Science Review this year will have a clear focus on water. The annual learning event will present more than a dozen sessions on getting the most from the nutrients in manure while limiting the chance of them reaching lakes and streams. It’s for farmers and others in the industry. “Manure is an excellent soil amendment and provides nutrients for crop growth,” said  ...

  • Southern California dealing with pesticides, fertilizers and other pollutants from area farms

    Regional water monitors in California recently announced that farmers in parts of the state will soon be required to finance all, or part, of the cost to monitor agricultural pollutants in area surface water. The California Regional Water Quality Control Board adopted the new rules in 2007 and they will go into effect in the next few years.Runoff from farms and cropland can cause fertilizers, ...


  • Nutrients in streams can mask toxic effects of pesticides on aquatic life

    Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems. Freshwater organisms are exposed to a number of natural and ...

  • Nutrient Management Plans: A Study in Cause and Effect

    It seems practical on the surface. Nutrient management plans (NMPs) should supply plants with ideal amounts of nutrients, minimize runoff, and maintain or even improve the soil condition. And the farmer behind the plan would work with a set of conservation practices designed to reduce harmful pollutants while still obtaining optimal crop yields. However, many U.S. Animal Feeding Operations (AFOs) ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • Northrop Grumman Grant Funds Dig at Rose State

    A grant to Rose State College by Aerospace and defense giant, Northrop Grumman, provided for the digging of a water well on the campus to be used for educational purposes. Rose State environmental science professor, Dan Ratcliff, said the well will help environmental science students understand important scientific ...


  • Is biochar the answer for ag?

    Scientists demonstrate that biochar, a type charcoal applied to soils in order to capture and store carbon, can reduce emissions of nitrous oxide, a potent greenhouse gas, and inorganic nitrogen runoff from agriculture settings. The finding will help develop strategies and technologies to reduce soil nitrous oxide emissions and reduce agriculture’s influence on climate change. A research ...

  • Using Liquid Manure to Fertilize Wheat? Consider Timing, Nitrogen Content

    Liquid livestock manure can be a great option as a spring top-dress fertilizer for wheat fields if applied during the appropriate window of time and if it has the right amount of nitrogen, according to research conducted by the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. In a report published in the latest issue of the college’s  ...

  • Cover Crops Add to Farm Sustainability

    A potentially record-setting U.S. corn harvest is underway. Many farmers can attribute the use of cover crops as one of multiple best management practices (BMPs) that help them increase yield year after year. Combined with BMPs of The Fertilizer Institute’s 4R Nutrient Stewardship program that promotes the application of nutrients at the right source, right rate, right time and right place, ...
