Cheap land and relatively small acre yields characterize dry-farming. Consequently Iarger areas must be farmed for a given return than in humid farming, and the successful pursuit of dry-farming compels the adoption of methods that enable a man to do the largest amount of effective work with the smallest expenditure of energy. The careful observations made by Grace, in Utah, lead to the belief that, under the conditions prevailing in the intermountain country, one man with four horses and a sufficient supply of machinery can farm 160 acres, half of which is summer-fallowed every year; and one man may,. | IMPLEMENTS FOR DRY-FARMING Cheap land and relatively small acre yields characterize dry-farming. Consequently larger areas must be farmed for a given return than in humid farming and the successful pursuit of dry-farming compels the adoption of methods that enable a man to do the largest amount of effective work with the smallest expenditure of energy. The careful observations made by Grace in Utah lead to the belief that under the conditions prevailing in the intermountain country one man with four horses and a sufficient supply of machinery can farm 160 acres half of which is summer-fallowed every year and one man may in favorable seasons under a carefully planned system farm as much as 200 acres. If one man attempts to handle a larger farm the work is likely to be done in so slipshod a manner that the crop yield decreases and the total returns are no larger than if 200 acres had been well tilled. One man with four horses would be unable to handle even 160 acres were it not for the possession of modern machinery and dry-farming more than any other system of agriculture is dependent for its success upon the use of proper implements of tillage. In fact it is very doubtful if the reclamation of the great arid and semiarid regions of the world would have been possible a few decades ago before the invention and introduction of labor-saving farm machinery. It is undoubtedly further a fact that the future of dry-farming is closely bound up with the improvements that may be made in farm machinery. Few of the agricultural implements on the market to-day have been made primarily for dry-farm conditions. The best that the dry-farmer can do is to adapt the implements on the market to his special needs. Possibly the best field of investigation for the experiment stations and inventive minds in the arid region is farm mechanics as applied to the special needs of dry-farming.
