  • Arsenic in field runoff linked to poultry litter

    Fields amended with poultry litter can accumulate significant levels of arsenic, according to studies by USDA-Agricultural Research Service (ARS) scientists and associates. These findings provide key information about the agricultural pollutants that can build up in agricultural soils over time—and possibly migrate into nearby streams and rivers. Poultry producers have sometimes ...

  • Compost filter socks improve runoff from Croplands

    Water runoff from cropped farm fields can contain large amounts of eroded soil as well as some of the fertilizer and herbicide. Expanding on existing conservation practices, a team of scientists has tested whether compost filters socks in grassed waterways would reduce sediment flow and retain dissolved chemicals in runoff. The researchers observed reduced sediment in a non-tilled field and ...

  • 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 ...

  • Fertilizers – a growing threat to sea life

    A rise in carbon emissions is not the only threat to the planet. Changes to the nitrogen cycle, caused in large part by the widespread use of fertilizers, are also damaging both water quality and aquatic life. These concerns are highlighted by Professor Grace Brush, from Johns Hopkins University in Baltimore, USA, in her historical review1 of landscape changes around Chesapeake Bay, a large ...

  • Fertilizer placement affects nutrient leaching patterns

    Controlled-release fertilizers (CRFs) are a widely used method of delivering nutrients to nursery container crops. The fertilizers contain encapsulated solid mineral nutrients that dissolve slowly in water, and are then released into substrates over an extended period of time. Although the use of CRFs is an accepted practice, growers and researchers are always looking for ways to decrease ...

  • Many Countries Reaching Diminishing Returns in Fertilizer Use

    By Lester R. Brown When German chemist Justus von Liebig demonstrated in 1847 that the major nutrients that plants removed from the soil could be applied in mineral form, he set the stage for the development of the fertilizer industry and a huge jump in world food production a century later. Growth in food production during the nineteenth century came primarily from expanding cultivated area. It ...

  • 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, ...


  • Green fertilizer demand grows on inflation, pollution concerns and shortages

    An agricultural crisis is brewing in the United States which is pulling farmers from several directions.  Crop shortfalls are pushing grain prices to record levels while fertilizer costs, already at record levels, are forecast to rise even further when the 2008 planting season begins. The 2007 planting season saw the price of fuel and fertilizer soar and while this year's grain crops prove ...

  • Love a lush, green lawn?

    A lush green lawn is lovely to look at, but too much of a good thing can be bad. Often, that beautiful lawn is the result of regular fertilizing. An abundance of nitrogen and other nutrients in natural waterways can cause trouble for aquatic plant and animal life. High levels of nitrogen and phosphorus can cause an overgrowth of algae in the water, which then blocks light from getting to native ...
