The purpose of this study was to determine the effect of increased soil moisture levels on
the decomposition processes in a peat-extracted bog. Field experiments, in which soil
moisture levels were manipulated, were conducted using 320 microcosms in the
Wainfleet Bog from May 2002 to November 2004. Decomposition was measured using
litter bags and monitoring the abundance of macro invertebrate decomposers known as
Collembola. Litter bags containing wooden toothpicks (n=2240), filter paper (n=480)
and Betula pendula leaves (n=40) were buried in the soil and removed at regular time
intervals up to one year. The results of the litter bag studies demonstrated a significant
reduction of the decomposition of toothpicks (p<0.001), filter paper (p<0.001), and
Betula pendula leaves (p

CASCO (Canada Starch Company) began operations in 1982 and was officially opened in May of 1983. Premier William Davis was in attendance. CASCO is a company whose roots can be traced back to 1858 when it was founded by W.T. Benson in Cardinal, Ontario. The company grew as corn uses were developed. Corn derived products now include: corn oil, liquid sweetener and feed for dairy and cattle. Starch is used as a finish for fine papers, a component in dry cell batteries, pharmaceuticals, wallpaper, film, tires, surgical dressings, plastics and plywood. Corn syrup is used in beverages, canned fruit, frozen seafood, licorice, ice cream and baking products. Corn solubles are used in animal feed, rubber substitutes, soap, paint and varnish. There are more than 250 industrial and food uses for corn
