  • Cover Crops Capture Nutrients to the Benefit of Farmers and Water Quality

    Many factors contribute to the excess phosphorous that stimulates algal systems in bodies of water such as Lake Erie. Sources of excess phosphorous include urban stormwater, factories, sewers, household wastes and lawn fertilizer, and in some areas runoff from fertilizers or manure applied to fields. Fortunately, many farmers are already doing their part to improve water. ...

  • Measuring calcium in serpentine soils

    Serpentine soils contain highly variable amounts of calcium, making them marginal lands for farming. Successful management of serpentine soils requires accurate measurement of the calcium they hold. Research published this month in the Soil Science Society of America Journal shows that multiple measurement techniques are needed to accurately measure calcium content in serpentine soils. To make ...

  • 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 scientists typically measure different aspects of soil — how much air it contains, how well it retains water, heat, and more — to ...

  • The Quest ATR is perfect for testing soil

    The ecological health of soil can be monitored with the Quest ATR. The organic and mineral components of soil can be established by testing with ATR-IR spectroscopy. Check your plants/crops/etc have the right nutrients for good health. Make sure there is enough calcium, not too much nitrogen or carbon. Map large areas according to the deficit or abundance of minerals. The ...

  • 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 ...

  • Past, present and future of soil sciences

    The Soil Science Society of America (SSSA) is reporting the results of a recent survey of trends related to the soil science profession. The results suggest that employment opportunities in soil and related sciences are increasing, and students, academics, and employers have a positive outlook for the future of soil science. Despite these positive findings, the survey identified areas to be ...

  • Cattle can help restore degraded soil

    Agriculture Research Service has tested cattle grazing on degraded soil to determine if the activity would have any effect on restoring depleted nutrients. During a 12 year period, 18 paddocks were used to monitor the soils response to different land management practices. In the end, the paddocks with medium to heavy grazing proved to be the best way to sequester nitrogen and carbon in the soil. ...

  • Method developed to measure solute movement in soils

    Scientists from Aarhus University and Aalborg University in Denmark have developed a new method for measuring the movement of solutes in intact soil. Improving on the existing method, the new procedure can be used on intact, undisturbed soil and provides more confident estimates. Movement, or diffusion, of solutes in soils is involved in many processes of agronomical, environmental and technical ...

  • 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 ...

  • Through microbes, nitrogen alters soil carbon cycle

    Soil scientists studying bacterial communities in hardwood forests have found evidence that extra human-derived nitrogen deposited from the atmosphere can change the composition of the soil microbial community, with implications for carbon cycling and sequestration. Don Zak and Sarah Eisenlord from the University of Michigan conducted a study on the response the soil bacterial community to levels ...

  • 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 ...

  • Improved soil water sensors aid in irrigation management

    Agriculture, a large user of water for irrigation, is under pressure to reduce water use. Increased urban population growth has created more competition for limited water supplies. While growers have used soil moisture probes to aid in irrigation management in the past, earlier probes required maintenance or were expensive or inadequate.  New electronic sensors have been developed that require ...

  • FAO launches new global soil database

    A new database on the world’s soils improves knowledge of the current and future land productivity as well as the present carbon storage and carbon sequestration potential of the world’s soils. It helps to identify land and water limitations, and assist in assessing the risks of land degradation, particularly soil erosion risks, said FAO this week. Derived from the soil database, FAO has produced ...

  • Ohio State Agronomy Workshop Jan. 19 to Focus on Soil Fertility

    Healthy soils are a key ingredient to produce strong crop yields, and understanding what nutrients your soils need is a fundamental step in that process, says an educator in the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. Soil fertility is crucial to maximizing yield potential when growing crops, said Amanda Douridas, an Ohio State University Extension ...

  • Artificial wetlands on farmland help to prevent soil loss and recapture agricultural by-products

    Small field wetlands are a simple and effective way to reduce soil erosion and nutrient pollution, recent research suggests. The authors adapted Norwegian designs for the UK environment and created a series of small rectangular lakes on the edges of agricultural fields. After three years, the wetlands had prevented tonnes of soil from leaving the land, and helped alleviate some of the nutrient ...

  • Asia–Pacific Analysis: Launching a second Green Revolution

    Feeding South-East Asia's rapidly growing population requires a second Green Revolution, says Crispin Maslog. The Day of Seven Billion was proclaimed by the United Nations Population Fund (UNFPA) on 31 October 2011 as a historic milestone — the day the world's population reached seven billion people. And the world is on a steep growth curve for the rest of this century. ...

  • Key to Life in the Desert: What New Research Reveals about the Importance of Soil Crusts

    Biological soil crust organisms found to play an active role in the development of soil structures and the allocation of water and nutrients Thursday, July 19, 2012 - Deserts creep outward in various directions across the western United States. The dry wind shuttles clouds of sand across the landscape, leading the charge to take over surrounding land, advancing the growing desertification ...

  • Analyzing agroforestry management

    The evaluation of both nutrient and non-nutrient resource interactions provides information needed to sustainably manage agroforestry systems. Improved diagnosis of appropriate nutrient usage will help increase yields and also reduce financial and environmental costs. To achieve this, a management support system that allows for site-specific evaluation of nutrient-production imbalances is needed. ...
