Several crops produced in the U.S. could play a significant role in biobased resins and coatings recently developed by researchers at North Dakota State University, Fargo. The NDSU researchers have developed a family of resins from renewable raw materials, creating resins that eliminate hazardous components such as formaldehyde and bisphenol-A. The resins are based on sucrose and vegetable oils, and can be varied to perform in many applications and industries.
New PNNL research explains how the carbon involved in crop production is unevenly distributed. More populated regions that depend on others to grow their food end up releasing the carbon that comes with those crops, leading those areas to become carbon sources.
Each year, plant diseases wipe out millions of tons of crops and waste valuable water resources. But a new discovery suggests that all pathogens attack plants via a surprisingly limited number of cellular targets. The finding could help researchers develop disease resistant crops and environmentally sustainable treatments for plant diseases.

A Kansas State University geographer is part of a research team out to prove what environmental scientists have suspected for years: Increasing the production of soybean and biofuel crops in Brazil increases deforestation in the Amazon. Although this cause-and-effect finding seems fairly straightforward, the issue of deforestation in the Amazon is more complex and more devastating than previously believed.
Although beneficial, farmers are often hesitant to use cover crops because of costs, time
Although considered an environmentally sound disposal method, applying sewage sludge to agricultural lands may leave harmful metals in the soil.

Agricultural producers and waterfowl will benefit from a project at South Dakota State University that uses an innovative plant-breeding technique to shave perhaps two years off the time needed to produce winter wheat varieties for farmers in the Prairie Pothole Region of North America.
University of Wisconsin-Madison scientists are part of an international consortium that has successfully sequenced and analyzed the potato genome. The consortium’s work, which is described in the current issue of Nature, turned up more than 39,000 genes and is expected to speed potato research and breeding projects around the globe.
Scientists develop model to assess the impact agroforestry windbreaks have on farming operations.
The prospect of rising temperatures in Iowa and the Midwest is predicted to lead to a dramatic decline in corn yield. With a $5 million grant from the U.S. Department of Agriculture, Iowa State University researchers Alan Myers and Tracie Hennen-Bierwagen are looking to develop a corn variety that maintains the region's high yields even as temperatures rise. The study is part of the response within the scientific community to challenges issued by the National Research Council in their report, "New Biology for the 21st Century: Ensuring the United States Lead the Coming Revolution."
The discovery that a bacterial species in the Australian Tammar wallaby gut is responsible for keeping the animal’s methane emissions relatively low suggests a potential new strategy may exist to try to reduce methane emissions from livestock, according to a new study.
Agroforestry management can improve yields and reduce environmental costs.
Scientists isolate single protein in potatoes responsible for an unhealthy compound produced when cooking at high temperatures.
Food prices are high worldwide and many factors are causing the increase, according to a Kansas State University agricultural economist.
Soybean growers in Argentina have something in common with their counterparts in some areas of the northern United States: Problems with a plant disease called northern stem canker.
Agricultural land values are booming again in the Northern Great Plains, if a South Dakota study is any indication. The latest study from South Dakota State University economists suggests South Dakota land values charted a 16.5 percent increase in 2010-2011.
Pollination typically brings to mind an iconic story of the bee visiting the flower in a lovely meadow. And everyone benefits from this ecological cooperation. But a closer look at the process in rangelands reveals a more complex picture of competition, attraction, negotiation, and, of course, the forces of the wind.
Scientists practice a method to help discover specific genes that determine fruit traits.
Research is being conducted on degrading a toxic compound found in groundwater systems around the world.

Our world of electronic conveniences has now reached the cow pasture. In the not-so-distant future, landscapes may be dotted only with virtual fences and cattle will be herded with global positioning system (GPS) technology. Of course, as with most electronics, how long the battery will last is still an issue. In this case, the amount of battery power a bovine can carry on the collar around its neck limits the use of technology.
