Profitable cultivation of land under dry-farm conditions is dependent on the efficient use of precipitation. Soil fertility is not at present the limiting factor in crop production on most arid lands, but insufficient moisture to make available the fertility of these dry-lands is not only a limiting factor, but in most cases the controlling factor in crop production. The rainfall in the principal dry-farming areas of Utah varies from 12 to 15 inches a year. During different years it may range from 10 to 22 inches; therefore the best use must be made of the water that falls.

Under normal precipitation the variety of crops which can be successfully grown in the West is limited. Of necessity, irrigation was practised and with it came many complex problems. The water requirements of different crops, the water-holding capacity of soils, the movement of soil moisture, and numerous other related problems have given themselves up for investigational work.

The progress of the work upon the general problem of the origin of the nitre spots in certain western soils has presented several different points of view. The fact that certain spots in western cultivated soils were rich in nitrates was first observed by Hilgard who attributed their accumulation to the more rapid nitrification of the organic matter of the soil in the warm arid climate of the west when the moisture limit was removed by irrigation.

The present bulletin describes the results of an experiment on the irrigation and manuring of corn for the six years from 1911 to 1916, inclusive. The first three years' results of this experiment have already been published as Bulletin No. 133 of this Station. Besides the material discussed in that publication the present bulletin contains data on the composition of corn here presented for the first time.
