"Soil moisture, its conservation and use by plants, forms one of the most important factors in successful crop production in Western Canada. Throughout the three Prairie Provinces in Manitoba, Saskatchewan and Alberta the average annual precipitation ranges from 13 to 20 inches. In the eastern portion of Canada the average annual range is from 30 to 40 inches. On this account farming practices in Western Canada, or specifically in the Prairie Provinces, differ considerably from those employed in the eastern part of the Dominion. The climate of the prairie areas is characterized by periods of moisture deficiency, especially in certain seasons, and special methods of soil cultivation are necessary to conserve moisture and to ensure profitable crop yields."--p. 3. gccst Soil gccst Drought gccst Crops gccst Crop rotation Hopkins, E.
