Publisher's Synopsis
Excerpt from The Problem of Crop Production
Water is generally the limiting factor in crop production here. In other words. It is the chief cause of low yields. From 250 to pounds of moisture is extracted from the soil and transpired by the plant into the air in the process of forming one pound of dry organic matter in its tissues. In Western Canada we receive from 12 to 20 inches of water from the clouds annually. The precipitation in most agricultural countries ranges between 10 inches and 150 inches per year. Our supply is small and our need is great. Man must furnish what. Nature does not supply. Otherwise he must be content with low yields.
