Saving the soil and maintaining corn yields: Early research says yes to both

ScienceDaily: Organic Farming News - Tue, 06/15/2010 - 04:00
Researchers are testing between-row cover grasses as part of research looking at ways to reduce soil runoff and keep vital nutrients in the soils while crop residue, called stover, is removed from farm fields to produce biofuels. Two years into a study, research is showing that yield can be maintained at high levels using environmentally friendly practices.

Absence of organic compounds on surface of Mars explained by new theory

ScienceDaily: Organic Farming News - Fri, 06/11/2010 - 00:00
The ongoing search for evidence of past or present life on Mars includes efforts to identify organic compounds such as proteins in Martian soil, but their absence to date remains a mystery. A new theory to explain what happens to these carbon-based molecules is presented in a new article.

Put more nitrogen into milk, not manure: Managing nitrogen on dairy farms

ScienceDaily: Organic Farming News - Fri, 05/28/2010 - 04:00
The more efficient dairy farmers are in managing nitrogen, the more milk their cows will produce and the less nitrogen will be wasted in manure and urine, according a study by agricultural scientists and cooperators.

How grazing lands influence greenhouse gas

ScienceDaily: Organic Farming News - Mon, 05/24/2010 - 21:00
Scientists estimated net global warming potential for three grazing management systems located in central North Dakota. The results indicate that grazing lands are strong sinks of soil organic carbon and minor sinks of methane, but small to moderate sources of nitrous oxide.

Organic solids in soil may speed up bacterial breathing

ScienceDaily: Organic Farming News - Mon, 05/24/2010 - 12:00
The "mineral-breathing" bacteria found in many oxygen-free environments may be "carbon-breathing" as well. Oxygen-free, or anaerobic, environments contain microbes sometimes described as "mineral-breathing" because they use iron oxides and other minerals in the same way we use oxygen. According to a new study, this bacterial respiration may be accelerated by solid organic compounds in the soil.

Wild birds opt for conventional food over organic, study shows

ScienceDaily: Organic Farming News - Thu, 05/20/2010 - 09:00
The nutritional benefits of organic food have been called into question by new research which shows wild garden birds prefer conventional seed to that which has been organically- grown. A three-year study by Newcastle University has found that wild birds are not swayed by the organic label, but instead prefer the more protein-rich, conventional food that will help them to survive the winter.

No-till farming improves soil stability, research finds

ScienceDaily: Organic Farming News - Fri, 05/14/2010 - 00:00
A new study across the central Great Plains on the effects of more than 19 years of various tillage practices shows that no-till makes soil much more stable than plowed soil.

Organic farming shows limited benefit to wildlife, researchers in UK find

ScienceDaily: Organic Farming News - Thu, 05/06/2010 - 06:00
Organic farms may be seen as wildlife friendly, but the benefits to birds, bees and butterflies don't compensate for the lower yields produced, according to new research in the UK.

New atlas underlines significant role of northern soils in climate change

ScienceDaily: Organic Farming News - Tue, 05/04/2010 - 04:00
European researchers have launched a soil atlas of the world's northernmost regions, where more than half the carbon present in Earth's soils is stored. Although there has been much focus on the melting of arctic ice as one of the indicators for climate change, 1700 billion tons of organic carbon are kept in the soils of the northern permafrost region and their thawing could lead to substantial release of greenhouse gases into the atmosphere and would further increase global warming.

Large amounts of nitrogen stored beneath selected agricultural areas

ScienceDaily: Organic Farming News - Mon, 05/03/2010 - 04:00
Scientists used a new version of the Root Zone Water Quality Model to estimate unsaturated zone nitrogen mass balances at four agricultural fields. The new version of the model can make predictions down to 30 meters, enabling estimation of water quality effects well beyond the root zone.

Organic snackers underestimate calories, study shows

ScienceDaily: Organic Farming News - Fri, 04/30/2010 - 12:00
Researchers show that "organic" labels on snack foods can lead people to underestimate the number of calories in their snacks by up to 40%.

Assessing antibiotic breakdown in manure

ScienceDaily: Organic Farming News - Wed, 04/14/2010 - 06:00
Agricultural scientists are studying how oxytetracycline, an antibiotic that is administered to animals, breaks down in cattle manure.

Energy crops impact environmental quality, review finds

ScienceDaily: Organic Farming News - Mon, 04/05/2010 - 09:00
A new review of scientific literature finds that removal of crop residue for biofuels can adversely impact soil and environmental quality. Conversely, dedicated energy crops can increase soil organic carbon concentration while providing biofuel feedstock.

Green food choice may not be so green

ScienceDaily: Organic Farming News - Fri, 04/02/2010 - 00:00
If everyone became vegan and so ate only fruit and vegetables, then the reduction in greenhouse emissions for the whole of food consumption would be a mere 7%. The widespread adoption of vegetarianism would have even less impact, while organic food production actually leads to a net increase in greenhouse gas emissions. Those are the conclusions of a research paper published in the journal Progress in Industrial Ecology.
