Manure runoff depends on soil texture
Research has documented the rise of nutrient runoff from flat agricultural fields with high rates of precipitation that adds nitrates and phosphates to waterways. These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of reducing ...

Fish farming finds its way to land-locked Midwest
The latest of five generations who have worked the same ground in northeastern Nebraska, 52-year-old Scott Garwood, isn't growing corn or cattle - it's fish. Specifically, thousands of an Australian freshwater species called barramundi - often dubbed Asian sea bass because of its similar sweet, white flaky flesh - in large tanks inside a warehouse. With global consumption of seafood outpacing ...

Tracking phosphorus runoff from livestock manure
Nutrient runoff from livestock manure is a common source of agricultural pollution. Looking for an uncommon solution, a team of scientists has developed an application of rare earth elements to control and track runoff phosphorus from soils receiving livestock manure. In addition to reducing the solubility of phosphorus, this method shows particular promise for researchers interested in tracking ...

A new tool to assess nitrogen and phosphorus flow in agriculture
MITERRA-EUROPE is a new tool that models the amount of nitrogen and phosphorus, among other key pollutants, used in agriculture across all 27 Member States at regional, country and EU-27 levels. It can be used to calculate the effects of different strategies to minimise excess pollution. Many regions in the EU-27 use more nitrogen and phosphorus in agriculture than is required. The main sources ...

Cover Crops Capture Nutrients to the Benefit of Farmers and Water Quality
Many factors contribute to the excess phosphorous that stimulates algal systems in bodies of water such as Lake Erie. Sources of excess phosphorous include urban stormwater, factories, sewers, household wastes and lawn fertilizer, and in some areas runoff from fertilizers or manure applied to fields. Fortunately, many farmers are already doing their part to improve water. For example, cover ...

Manure from millions of hogs fuels natural gas project
One recipe for renewable natural gas goes: Place manure from about 2 million hogs in lagoons, cover them with an impermeable material and let it bake until gas from the manure rises. Then, use special equipment to clean the gas of its impurities and ship the finished product out. That's the vision of one of the largest biogas projects of its kind in the U.S. currently being installed in northern ...
