Although rarely conducted as an independent enterprise, poultry-raising has had perhaps the greatest increase of any farm industry. Some type of fowl is raised on approximately 89 percent of the farms of the State. In 1929 North Dakota was listed second in the production of turkeys, twenty-fifth in poultry and eggs, thirteenth in ducks, and fourteenth in geese. Poultry organizations are active in the State. The North Dakota State Poultry Association has held annual shows since 1895, the All-American Turkey Show is held annually in Grand Forks, and there are numerous regional and county organizations. The North Dakota Farmers Union maintains a poultry cooperative at Williston. North Dakota is second only to Texas in supplying turkeys for the Thanksgiving and Christmas tables of the Nation. The multitudes of wild flowers on the North Dakota prairies are an abundant source of honey; and with this natural incentive to its development, beekeeping has increased rapidly throughout the State. Although it can be successfully conducted in almost every part of the State, the most extensive areas are along the Missouri and in the Red River Valley. The sweet clover bloom is the chief source of honey, and yields abundantly in July and August. The number of bee colonies in the State increased from 32,000 in 1929 to 35,000 in 1932. All of North Dakota was affected by the prolonged drought in the Great Plains States which began in 1929 and, except for one year, continued through 1936. High winds, intensive cultivation, and low rainfall combined to create the most destructive period of soil erosion known to the State since its earliest settlement. This combination of conditions brought production in all farm products far below normal levels. Even the Red River Valley, though it fared much better than the western part of the State, had subnormal rainfall and was subjected to frequent dust storms. To counteract the menace of drought to the prosperity of a primarily agricultural region, both State and Federal agencies began promotion of conservation in three forms: water, soil, and vegetation. Through the combined efforts of private groups and governmental agencies, ponds, marshes, lakes, and streams are being restored. Some irrigation projects, both private and public, have proved fairly successful in the western counties. The contemplated Missouri River diversion projects, with the Grand, Knife, and Heart sub-projects, would lead to reclamation of a large area of North Dakota. Planting hedges and forests to hold moisture in the soil and to prevent increased erosion constitutes the soil conservation program. To conserve vegetation, a program of dry-farming is recommended, including summer fallowing and the planting of drought-resistant crops.
