University of Guelph study assesses environmental impact of Ontario corn production

14.02.2014
Researchers at the University of Guelph examined the energy use and greenhouse gas (GHG) emissions associated with corn production in Ontario. Their findings are published today in the Agricultural Institute of Canada's (AIC) Canadian Journal of Soil Science.

The study reports estimated county-level energy and GHG intensity of grain corn, stover and cob production in Ontario from 2006-2011. According to the paper's authors, most of the energy used during corn production comes from the use of natural gas and electricity during grain drying; the production and application of nitrogen fertilizers (which are also associated with GHG emissions); and the use of diesel fuel during field work.

"Corn is a major economic crop in North America, and the renewable fuels developed from corn production are frequently used to mitigate the GHG emissions from fossil fuel use," explained Susantha Jayasundara, lead author of the paper.

"Assessing the GHG and energy intensity of corn production helps identify opportunities for efficiency and aids in improving the GHG mitigation potential of corn-derived renewable fuels," continued Jayasundara. The authors note that reducing GHG intensity and improving energy efficiency during corn production can be achieved through the use of field-drying corn hybrids, reduced tillage and diminished nitrogen inputs.

The article, "Energy and Greenhouse Gas Intensity of Corn (Zea Mays L.) in Ontario: A regional assessment," by Susantha Jayasundara, Claudia Wagner-Riddle, Goretty Dias and Kumudinie Kariyapperuma, is available Open Access in the Canadian Journal of Soil Science.

"Given the environmental and economic benefits of renewable fuels and the proliferation of their use in Canada, it is important to more fully understand the environmental impacts of their associated agricultural production," added Serge Buy, CEO of AIC. "Essential studies such as this are of national significance and are certainly evidence of the need for targeted federal investments in agricultural science."

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
