As the discussion about climate change increases so has the discussion about the possibility of reducing or offsetting greenhouse gas emissions by natural plant and soil processes. In green house gas accounting, atmospheric CO2 concentration is not increasing at a rate equivalent to estimated annual green house gas emission caused by burning of fossil fuels and by land use change (e.g. deforestation). This short-fall in the greenhouse gas balance sheet is an indication that CO2 is actively being taken out of the atmosphere in large quantities through photosynthesis. The only biological entities large enough to do this are the, forests, grass and crop lands of North America. This is the “Miss
Van Schothorst is inclined to believe that bacteria must be transmitted in ways other than by flies because several herds in southern Alberta have histories of pinkeye occurring in winter and worsening throughout the summer, and many ranchers say that the period after weaning is a high-risk time for pinkeye. “I had the idea when I looked at herds dealing with outbreaks that the eye and nose communicate with each other. In most mammals, the naso-lacrimal duct drains tears into the nose, therefore, perhaps aerosolized nasal secretions or even nose-to-nose contact would be the more likely predominant mode of transmission,” she explains. Another perplexing aspect of pinkeye is that even though M
Introduction Frost seeding is an economical method of improving pasture and hay fields by broadcasting the seed on frozen ground. As the ground freezes and thaws, it opens and closes allowing the seed to be incorporated into the soil. This keeps the seed from germinating until there is a good moisture supply early in the spring. Legumes are the most successful for this system as they tend to be rounded, dense and most importantly, they -germinate at lower temperatures so will begin growth early in the spring. Grasses have not been as successful as they are lighter coloured, less dense thus they sit on top of the ground and wait for warmer temperatures to begin growth. This often coincides wi
