  • 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 ...

  • 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. ...

  • 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 ...

    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 ...

  • 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 ...

  • Quality Organic Fertilizers & Soil Amendments at an Affordable Price

    Our health starts with our soil. If the soil in our farms and gardens is depleted of life because of chemical and fertilization, the food will be sterile and not healthy. They key to a healthy body, soul, and mind is organically grown food that is full of life. “When the things we put into our bodies are healthy, our bodies are able to utilize the nutrients with very little energy. This ...

  • 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 ...

  • 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 ...

  • 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. ...

  • The Importance of Soil Sampling – Liquid Fertiliser Tanks Store Fertilizer Efficiently

    The importance of soil sampling was reinforced by Farming Life this week. It stated that good productive soils are the foundation of any successful farm system and that the ability of soils to supply nutrients at a time and in an appropriate quantity for grass and crop can be key to determining productivity. Therefore, a farms ability to manage soil fertility levels should be a primary objective. ...

  • When it comes to forest soil, wildfires pack one-two punch

    For decades, scientists and resource managers have known that wildfires affect forest soils, evidenced, in part, by the erosion that often occurs after a fire kills vegetation and disrupts soil structure. But, the lack of detailed knowledge of forest soils before they are burned by wildfire has hampered efforts to understand fire’s effects on soil fertility and forest ecology. New research ...

  • 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. ...

  • 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 ...

  • Finding the real potential of no-till farming for sequestering carbon

    The potential of no-tillage (NT) soils for increasing the soil organic carbon (SOC) pool must be critically and objectively assessed. Most of the previous studies about SOC accrual in NT soils have primarily focused on the surface layer (<20-cm soil depth), and not for the whole soil profile. The lack of adequate data on the SOC profile is a hindrance to conclusively ascertain the effects of ...

  • Tillage and reduced-input rotations affect runoff from agricultural fields

    A new study from researchers at the USDA Agricultural Research Service provides information about runoff under different management practices and can help farmers choose the practice that is best for them. No-till management practices can reduce soil erosion, but evidence suggests they can also lead to increased runoff of dissolved phosphorus from soil surfaces. Meanwhile, farmers looking ...
