  • 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, ...

  • States Develop New Strategies to Reduce Nutrient Levels in Mississippi River, Gulf of Mexico

    Summary The 12 states of the Hypoxia Task Force have devised new strategies to speed up reduction of nutrient levels in waterways in the Mississippi/Atchafalaya River Basin. High nutrients levels are a key contributor each summer to the large area of low oxygen in the Gulf of Mexico known as a dead zone. Each state has outlined specific actions it will take to reduce nitrogen and phosphorus ...

  • 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 ...

  • Tidal Marshes protect aquatic ecosystems and store carbon

    A team of scientists measured nitrogen and phosphorus retention and carbon sequestration by tidal marsh soils along the Georgia coast to document the role of these wetlands in storing carbon and removing nutrients at the landscape scale. The results suggest that tidal marches protect aquatic ecosystems from eutrophication, caused by the accumulation of nutrients that disrupts ecosystems and ...

  • 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 ...

  • 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 ...

  • Vermicompost leachate improves tomato seedling growth

    Worldwide, drought conditions, extreme temperatures, and high soil saline content all have negative effects on tomato crops. These natural processes reduce soil nutrient content and lifespan, result in reduced plant growth and yield, and ultimately translate to lower profits for tomato producers. As an alternative to unsustainable practices such as the use of synthetic fertilizers, producers are ...

  • Vegetables can absorb heavy metals from contaminated irrigation water

    Certain vegetables take up heavy metals from contaminated water used for irrigation, a new study finds.
