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 C

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

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
