  • Climate change to disrupt soil nutrients in drylands

    The increased aridity expected this century as a result of climate change may disrupt the balance of key soil nutrients with a knock-on effect on soil fertility threatening livelihoods of more than two billion people, a study finds. The drop in nitrogen and carbon concentrations that occurs as soils become dryer could have ...

  • Food security depends on sustainable nutrient management of soils

    Food security is being threatened by loss of soil nutrients that are essential for the high yield of crops. A recent study outlines strategies to ensure the sustainable production of food through a holistic approach to soil nutrient management. In response to the rising demand for food from an increasing world population, high-yielding crops are being grown with the help of artificial fertilisers ...

  • Increasing aridity will disrupt soil nutrient cycles in global drylands

    The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth’s land surface, according to new research. The study focused on ‘drylands’ – arid areas with low levels of rainfall – which support over 38% of the world’s population. Such nutrient imbalances could diminish the provision of ecosystem services, such as ...

  • Soil biodiversity reduces nitrogen pollution and improves crops’ nutrient uptake

    Increased soil biodiversity can reduce nitrogen pollution, improve nutrient uptake by plants and even increase crop yields, new research suggests. The two-year study found that levels of nitrogen leaching from soil with an abundant soil life were nearly 25% lower than for soil with a reduced level of soil life. Practices which enhance soil biodiversity such as reduced tilling, crop rotation and ...

  • Host of Nutrient Platform Members Meeting

    Coming Thursday, March 23rd, Eijkelkamp Soil & Water will host the Members Meeting of the Nutrient Platform. The Nutrient Platform is a cross-sectoral network of Dutch organizations that believe in a pragmatic approach towards nutrient scarcity. Frontrunners, like Eijkelkamp Soil & Water, from the water sector, agriculture, waste sector and chemical industry have joined forces to close ...

  • Free webinar: Managing nutrients after the drought

    Join a panel of experts as they discuss how to practice good nutrient management in the wake of this year's drought Sponsored by the Agricultural Nutrient Policy Council and hosted by the American Society of Agronomy The drought of 2012 will long be remembered for its devastating effects on crops across a huge swath of North America's most productive soils. And ...

  • New foliar nutrient to improve sugar beet yields

    How it works The early growth stage is crucial to sugar beet yield, as sugar accumulation begins from very early in the growth cycle. Optimising nutrition during this important early phase encourages more even, healthy leaf growth and more productive photosynthesis when the sun shines. With the higher nutrient demand of sugar beet for NPK, Magnesium and essential micronutrients such ...

  • 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) ...

  • New software helps farmers manage nutrients

    University of Missouri Extension has released a new Web-based application to help farmers manage soil nutrient needs on farms. Nutrient management helps farmers set rates and timing of fertilizer applications, said John Lory, MU Extension nutrient management specialist. Plans are required for some farms in cost-share programs and permitted animal feeding operations. The free MMPTracker tool is ...

  • Nutrient levels on the decline in many Estonian rivers

    A new study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites. High levels of nutrients, such as nitrogen and phosphorus, ...

  • 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. ...

  • Managing nutrients presents both challenges and solutions to food security

    As global populations increase, a growing demand for food can be achieved through sustainable production and use of fertilizers which if not managed correctly will impact food security as well as water quality and availability, fisheries and biodiversity, says a report launched today by the United Nations Environment Programme (UNEP). The report, Building the Foundations for Sustainable Nutrient ...

  • 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 ...

  • Safeguarding our soils for the future

    Measures to protect and improve our soil to meet rising demand for food and to combat climate change have been unveiled by Environment Secretary Hilary Benn. England’s soil has suffered over the last 200 years from the impacts of intensive farming and industrial pollution, and today is under threat from erosion by wind and rain, a loss of organic matter and nutrients, and pressure for ...

  • 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. Avoiding bare soils is one part of a soil conservation package he and his research team demonstrate in a 12-year experiment growing pulses in southern ...

  • 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 ...

  • Manure runoff depends on soil texture

    Research has documented the rise of nutrient runoff from flat agricultural fields with high rates of precipitation that adds nitrates and phosphates to waterways. These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of reducing ...

  • Mysteries of soil and nitrogen to be probed at Jamestown

    Making better use of soil moisture and nitrogen will be a major focus of the Grains Research and Development Corporation (GRDC) Update at Jamestown on August 19. GRDC Southern Regional Panel chair David Shannon said improving efficiencies in the use of moisture and nutrients was an important investment for the GRDC and keenly sought by growers in South Australia’s Mid North. “While the ...

  • Critical Issues in Global Soil Health

    Soil health is rarely equated into discussions of climate change, environmental protection, and sustainable development. However, soils play such a vital role in the planet’s survival that life cannot exist without them. They provide the basis for food and fiber production; support a diversity of plant, animal, and microbial life; and regulate nutrient cycles and gas exchange with ...

  • 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 ...
