Nitrogen is needed to feed a growing world population but pollutes air, soil and water A major new study finds that nitrogen pollution is costing each person in Europe around £130 - £650 (&eur;150 "“ &eur;740 Euros) a year. The first European Nitrogen Assessment (ENA) is launched at a conference today in Edinburgh, Scotland. The study, carried out by 200 experts from 21 countries and 89 organizations, estimates that the annual cost of damage caused by nitrogen across Europe...

The growing world population relies on the help of nitrogen for our food supply, yet its very use pollutes the air, soil and water. The first European Nitrogen Assessment (ENA), launched at a conference today, estimates that nitrogen pollution will cost Europe an annual of &eur;70 to &eur;320 billion ($100-$460 billion USD) in damages. It found that the nitrogen pollution contributes to climate change as well as biodiversity loss. "Nearly, half the world's population depends on synthetic,...

Shallow disk injection found to be economically sound and environmentally safe, a technique that could help reduce nutrient runoff into the Chesapeake Bay Recycling manure is an important practice, especially for large livestock producers. Manure can be used as fertilizer to aid in crop production, aiding livestock producers that grow their own feed crops. While manure does provide a rich nutrient source for crops, it also can contribute to nutrient leaching and runoff. This can contaminate...

Low-cost removal of slurry solids also a creates a higher nitrogen to phosphorus ratio Manure has long been used as a crop fertilizer, but the challenge of finding an efficient use of the nutrients found in manure is ever present. The ratio of nitrogen to phosphorus in manure is low in relation to the nutrient needs of most crops. Therefore, crops tend to be overloaded with manure to meet the nitrogen requirement of agricultural crops, but the excess phosphorus from the process can damage the...

Danish Study Examines Relationship between Soil Texture, Nutrient Leaching, and Waterway Contamination 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...

Study simulates long-term effects of biofuel production on soil The growing development and implementation of renewable biofuel energy has considerable advantages over using declining supplies of fossil fuels. However, meeting the demands of a fuel-driven society may require utilizing all biofuel sources including agricultural crop residues. While a useful biofuel source, crop residues also play a crucial role in maintaining soil organic carbon stock. This stock of organic carbon preserves...

Study examines estrogen concentrations in manure runoff There is considerable amount of uncertainty concerning the environmental impacts that animal hormones have on surface water. Higher concentrations of hormones in waterways have been found to cause physiological and sexual impairment in fish and other aquatic species. However, a study from the University of Delaware that examined estrogen concentrations runoff from agricultural fields fertilized with chicken manure found that it is as...

AUSTIN, Texas, Sept. 17 /PRNewswire/ -- While Texas gubernatorial candidates Rick Perry and Bill White sling mud at each other, a Texas company, Cow Wow, has united the two politicians -- mounting them on the back of a 16-foot trailer for a Texas-style tour. Cow Wow, a liquid compost product, is launching a "Moovement," the "Heads of State," featuring six-foot terra cotta busts of Perry and White, with hair of ivy. The public is invited to text or vote online for the candidate with the...

Scientists find low levels of bacteria in fields sprayed with swine manure 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 Laboratory at...

Scientists develop application of rare earth elements to control 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...

Enviropig is the trademark for a genetically modified line of Yorkshire pigs with the capability to digest plant phosphorus more efficiently than ordinary unmodified pigs that was developed at the University of Guelph. The benefits of the Enviropig, if commercialized, include reduced feed cost and reduced phosphorus pollution as compared to the raising of ordinary pigs. Enviropigs create the enzyme phytase in their salivary glands. When cereal grains are consumed, the phytase mixes with...

Image Caption: A field in Randers, Denmark. A pile of manure is in the foreground. Credit: Malene Thyssen/Wikipedia (CC BY-SA 2.5) Manure is organic matter that comes from farmyard animal waste as well as from crop cover. Manure from cows, pigs, horses, chickens, rabbits, etc. is broken down into organic matter and used as organic fertilizer. “Green” manure is derived from planting a cover crop, such as clover, to be plowed directly back into the soil. Bacteria traps nitrogen and other...

Image Caption: Compost barrel with compost and tools. Credit: Diego Grez/Wikipedia Compost is fertilizer made from decomposed organic matter that is then tilled directly into the soil or used as an additive when transplanting seedlings. Composting can be very simplistic or complex, depending on the amount of compost needed. Compost is widely used in organic farming because of its high nutrient content and natural pesticide abilities. Composting is simply piling, systematically,...
