5200 |a"This bulletin presents the results of twelve years' study of soil moisture problems conducted by the Division of Field Husbandry of the Central Experimental Farm, Ottawa, at the branch farm located at Swift Current, Saskatchewan. The results to date indicate that the most feasible method of partially counteracting the effects of drought lies in improved methods of crop production whereby better use can be made of the available moisture, and whereby part of the annual loss can be prevented."-- Introd., p. 3.
