FOR many years a nutritional deficiency in cattle has been observed on many farms in Carroll County, N. H., and within the past two years it has been found that this deficiency responds to the feeding of cobalt (6) This, or a similar deficiency, occurs also in some parts of Massachusetts, Michigan, Wisconsin, North Carolina, and Florida (i,), and in some other parts of the world (8). During the past two years this deficiency has been found to occur on some farms in other parts of New Hampshire. The deficiency is sufficiently widespread and is of such importance to the individual dairyman that since about July i, 1945, many of the feed manufacturers serving New Hampshire have been adding cobalt to dairy feeds. Inasmuch as a very large portion of the concentrates fed in New Hampshire are mixed commercially, it is probable that the deficiency will not be of particular importance' hereafter and it will not be possible to observe the locations where such deficiencies are most likely to occur. During the year just before cobalt was added to the commercially mixed feeds, 126 farms were located in the state on which the deficiency in cattle occurred and considerable information regarding these farms was obtained. It is the purpose of this paper to report on the relationship that exists between the deficiency and the soils on these farms.
