  • 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 ...

  • Chesapeake Bay Nutrient Trading

    Proposed federal legislation to improve the health of the Chesapeake Bay could help a typical Maryland crop farm earn an additional USD10,000 in net profit each year, according to a new analysis by the World Resources Institute (WRI). The analysis, How Baywide Nutrient Trading Could Benefit Maryland Farms, forecasts the potential profits to farmers who participate in an interstate nutrient ...

  • 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 ...

  • 4R Research Fund Issues Proposal Requests for Research on Nutrients in the Environment

    This week, the 4R Nutrient Stewardship Research Fund announced the release of requests for proposals (RFP) to solicit literature reviews and syntheses on nutrient stewardship on a national, regional, or cropping system basis, and to solicit field research and demonstration projects. The 4R Research Fund was established by the fertilizer industry to help establish ...

  • New Fact Sheet Helps Chesapeake Bay States Design Nutrient Trading Programs

    2011 will be an important year for the Chesapeake Bay, not only because scientists are predicting an unusually bad “dead zone” this summer. Last December, the Environmental Protection Agency (EPA) issued ...

  • A model to measure soil health in the era of bioenergy

    One of the biggest threats to today’s farmlands is the loss of soil organic carbon (SOC) and soil organic matter (SOM) from poor land-management practices. The presence of these materials is essential as they do everything from providing plants with proper nutrients to filtering harmful chemical compounds to the prevention of soil erosion. Sustainable management practices for crop residues are ...

  • 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 ...

  • Dioxin risk in soil and plant tissues after long-term biosolids application

    Land application of biosolids (treated municipal sewage sludge) is a common practice because biosolids are a rich source of plant nutrients and organic matter. However, the presence of detectable levels of dioxins in biosolids led to concerns that farmland application may result in accumulation of dioxins in soil and their subsequent translocation through the human food chain because several ...

  • New Tool Offers Growers Easy Option to Measure Soil Organic Matter Content

    Researchers with Ohio State University's College of Food, Agricultural, and Environmental Sciences have developed a new tool that allows farmers to easily predict soil organic matter content and can help them make decisions about whether or not to sell crop residue. The tool can benefit growers by providing information for more timely planting and harvesting, reducing operating costs, increasing ...

  • IKEA, along with american forests, continues the success of its `plant a tree program`; together they have planted 1.9 million trees across America

    Why? Because planting trees will help to clean the air and cool the globe. Since 1998, IKEA US, in partnership with American Forests, has been dedicated to improving the lives of many people through its national in-store 'Plant A Tree' program, a campaign that asks customers to donate $1 to plant one tree. These contributions, together with money donated by IKEA, have resulted in the raising of ...

  • IKEA celebrates the planting of 1.5 million trees together with American forests across America

    Plant a Tree. Clean the Air. Cool the Globe. This thought has been the driver that has inspired IKEA US shoppers. Since June 2006, IKEA US in partnership with American Forests, has had a national in-store 'Plant A Tree' program which asks customers to donate $1 to plant one tree. These contributions, together with money donated by IKEA, have resulted in raising $1.5 million dollars to plant 1.5 ...

  • Cleaning up the baltic sea with mussel power

    Excess nutrients in seawater can cause eutrophication, a major environmental concern. Shellfish species such as mussels can 'soak up' some of these nutrients. A recent Swedish study examines the cost-effectiveness of mussel farming in the Baltic Sea as a method of reducing nutrient concentration and compares its potential with other methods of combating eutrophication. Eutrophication, caused by ...

  • High-nature-value grasslands can be maintained by alternating between mowing and grazing

    Scientists recommend policies that alternate between mowing and grazing to manage Europe’s high-nature-value grasslands. This comes after a new seven-year study found that a high plant-species diversity helps grasslands to maintain productivity and to resist depletion of phosphorus caused by livestock grazing and depletion of potassium caused by mowing. Grasslands with high levels of ...

  • CleanGrow introduces first-in-kind multi-ion CNT-based sensor for horticultural and other applications

    This week at Horti Fair in The Netherlands, the horticulture industry's premier tradeshow, CleanGrow will introduce its breakthrough multi-ion measurement solution capable of analyzing up to six ions simultaneously. The product combines a carbon nanotube-based sensor with a multi-ion meter for on-site measurements and real-time feedback. Currently optimized for horticultural applications, the ...

  • Maryland, Michigan Farmers Keep Soil, Environment Healthy

    As farming practices increasingly attract interest from the general public, two farmers are ensuring they meet public approval. They use proven management practices that focus on improving soil quality and maintaining a quality natural environment. In fact, getting the right nutrients to where they belong and in the right amounts when they’re needed enables them to improve yields while ...

  • 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 ...
