History of the Glenlea Study
This long-term, large-scale study was established in 1992 and is completing its 14th year in 2005. The Glenlea study contains many different crop production systems, including western Canada's oldest organic cropping systems. This study is unique in that each replicate contains a one acre restored prairie grass planting, which serves as a benchmark site for soil and environmental measurements.

The objectives of the study are:

	To compare the biological and economic performance of conventional, low input and organic crop production systems
	To monitor the impact of crop rotation and input level on pest population dynamics (annual and perennial weeds, insects, and crop diseases)
	To determine the long-term effects of different cropping systems on soil and environmental quality, using a restored tallgrass prairie treatment as a benchmark
	To provide a facility for undergraduate and graduate student training
