  • Nutrients in streams can mask toxic effects of pesticides on aquatic life

    Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems. Freshwater organisms are exposed to a number of natural and ...

  • North Sea needs more protection from nutrient inputs

    Reductions in the nutrients nitrogen and phosphorus flowing from rivers into the North Sea have had clear benefits on marine health in coastal waters, according to a recent study. However, the reductions are less effective in improving the condition of deeper offshore waters. Tougher measures to manage nutrient loads and prevent eutrophication are recommended. Reductions in nutrient levels in ...

  • 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 ...

  • Integrating animal and crop production can reduce nutrient leaching from agricultural fields

    Nutrient leaching, the movement of plant nutrients from soil to water, can have negative effects on aquatic ecosystems due to eutrophication, which reduces the oxygen available in water, causing species and habitat loss. Ecological Recycling Agriculture (ERA), which is based on ecological principles and integrates crop production and animal husbandry, may limit this effect. This study ...

  • 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 ...

  • Rising CO2 levels likely to have impact on soil, says EU

    One issue of concern is the relationship between above ground (e.g. by trees) and below ground (e.g. by soil microbes) carbon cycling. Soil fertility appears to play an important role in this process as higher CO2 levels lead to greater competition between microbes and trees for soil nutrients, according to new research.  Soils are an important sink for carbon and understanding how microbes that ...

  • 1980-2014: U.S. Corn Production More than Doubles; While Fertilizer Use Remains Almost Level

    The Fertilizer Institute (TFI) announced today that between 1980 and 2014, U.S. farmers more than doubled corn production using just under six percent more fertilizer nutrients than were used in 1980.  The announcement is based on fertilizer application rate data released today by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS).   ...

  • 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. ...

  • 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 ...

  • 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 ...
