Why you want to measure nutrient levels in water
Recently the guardian published an article on the largest ever 'dead zone' in the Gulf of Mexico. Nutrients flowing into streams, rivers and the ocean from agriculture and wastewater stimulate an overgrowth of algae, which then decomposes. This results in hypoxia, or lack of oxygen in the water, causing marine life either to flee or die. The algae blooms themselves can be toxic and cause all ...

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 ...

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 ...

Researchers investigate ultra-low Mediterranean nutrient levels
Researchers at Haifa University’s Marine Biological Station in Israel are exploiting the ultra-low detection limits of advanced laboratory equipment to measure extremely low nutrient concentrations in marine water. The University’s Prof. Krom says: "We work in the Eastern Mediterranean which has the lowest regional concentration of dissolved nutrients anywhere in the global ocean. We ...

Climate change and pollution threaten fishing catches
Warming of coastal areas due to climate change is already having an important impact on fishing catches in the North Atlantic, according to a new study. The study also suggests that rising levels of nitrogen pollution, due to run-off from farming and sewage disposal, will pose a serious threat to fisheries in the near future if left unchecked. At the World Summit on Sustainable Development in ...

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 ...

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 ...

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 in ...

Free Webinar: Optimizing Soil Health by Managing Nutrients
With today's challenges, it's becoming increasingly important to practice land stewardship, protect water quality, and ensure food security. Maintaining soil health is crucial for increased crop productivity, preventing nutrient runoff, and decreasing costs of crop inputs. One of the first steps in managing soil health is knowing current nutrient levels in the soil. During this free webinar, ...

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 ...

Latest LIBERTY agronomic data shows viability of biomass harvesting
Harvesting crop residue for cellulosic ethanol production is consistent with good farm management, according to the latest data from researchers with Iowa State University and USDA. The work was commissioned by POET-DSM Advanced Biofuels to ensure the sustainability of the joint venture’s plans to build cellulosic ethanol plants and license technology to producers in the U.S. and abroad. ...

Jellyfish infestations caused by human activities
A huge rise in jellyfish populations around the world appears to be caused by human activities, according to recent research. Early action is essential to prevent marine ecosystems from changing to unhealthy states that favour destructive jellyfish blooms. Although large numbers of jellyfish can occur in healthy marine ecosystems, destructive jellyfish blooms are being observed more frequently ...

Super hanging basket liners
As budding gardeners welcome the arrival of spring and start preparing their hanging baskets and planters, a new innovative water-retaining liner fabric will help make nurturing and caring for plants a lot less time consuming and reduce overall water usage. The Super Absorbent Fibre (SAF) technology of UK based manufacturer Technical Absorbents Ltd (TAL), is a unique fibrous technology and which ...

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 ...

Boost Grass Yields – Liquid Fertiliser Tanks
According to the Western Morning News, dairy farmers could significantly boost their grass yields by paying closer attention to detail when applying slurry this spring. As the closed spreading period is now over, farmers will be keen to get on spreading manure as they get a window in the weather. By adopting a more scientific approach to manure usage, producers may be able to dramatically ...

Increased amphibian mortality due to agri-chemical pollution
Global decline in frog populations is thought to indicate environmental damage caused by human activity. In particular, the use of agri-chemicals has been linked to an increase in infectious diseases in amphibians. A link has now been found between a parasitic infection and localised interaction between phosphate fertilisers and herbicides. Leopard frogs from wetlands in Minnesota, USA, were ...

Compost made by worms from livestock manure yields benefits when applied to maize
Vermicomposting livestock manure with maize can increase agricultural benefit by 304%, shows a new study. The combination of increased crop yield and the additional earthworms produced as a result of the process led to a substantial increase in output compared to a traditional composting system. As intensive agriculture and livestock production both increase, unique problems emerge. Heavy use of ...

Algae Key in Pilot Project
A pilot project this summer between Rochester Institute of Technology and Wyoming County-based Synergy Biogas LLC could reduce an environmental concern, solve a disposal problem and lead to a new way to produce fuel for vehicles—all through the use of algae. Jeffrey Lodge, associate professor in the Thomas Gosnell School of Life Sciences, is running a three-month pilot program at Synergy ...

Quality Organic Fertilizers & Soil Amendments at an Affordable Price
Our health starts with our soil. If the soil in our farms and gardens is depleted of life because of chemical and fertilization, the food will be sterile and not healthy. They key to a healthy body, soul, and mind is organically grown food that is full of life. “When the things we put into our bodies are healthy, our bodies are able to utilize the nutrients with very little energy. This ...
