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 ...

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, ...

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 ...

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 ...

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 ...

Balancing Act: Reconciling the Laws of Minimum and the Maximum
Does going to the extreme in fertilizer application overcome yield limitations? When it comes to plant development and yield, imbalance is more likely to threaten soil health, production and your pocketbook. Instead, achieving nutrient balance is crucial to crop success. With that in mind, we reflect on the often-perceived conflicting theories – Liebig’s Law of Minimum and ...

Nitrogen use by warm-season grasses for biomass production
Perennial, warm-season grasses are being evaluated as potential renewable energy crops. These species are well-suited for the production of biomass for energy applications because they utilize C4 photosynthesis and are perennial. Grasses that employ the C4 photosynthetic pathway use water, nitrogen (N), and solar radiation more efficiently than plants having the C3 pathway, and therefore are ...

UNEA-4 Adopts Resolution on Sustainable Nitrogen Management: Global Fertilizer Industry Committed to Doing Its Part
The Resolution on Sustainable Nitrogen Management, adopted at the 11-15 March UN Environment Assembly in Nairobi, calls for coherent evidence-based, global policy coordination to address negative impacts of reactive nitrogen stemming from multiple sources. “With the numerous uses of nitrogen in industrial transformation, energy production, and, of course, plant nutrition, IFA welcomes this ...
