Excerpt from Soils of the Eastern United States and Their Use XII: The Carrington Loam

Carrington loam is developed, agriculture is just passing through its pioneer stages, crop rotation is not generally practiced, the feeding of live stock is subordinate to grain production, and practically no stable manure is saved or applied to the land. As a result there has been some decrease in the cr0p yields of the type during the past 15 or 20 years, and the farmers in these regions are becoming convinced of the necessity for crop rotation, the introduction of animal husbandry, and the application of manures in order that the Original efficiency of the type may be restored, maintained, or even increased.

In Minnesota and North Dakota, where the Carrington loam is extensively developed, the principal improvements in soil efficiency can be effected by the adoption of a regular crop rotation, utilizing the considerable variety Of general farm crops well suited to produc tion upon this type and capable Of production under the climatic conditions which exist. In numerous instances where the practice of crop rotation has already been adopted material increases in yield, both of corn and of spring wheat, have been attained, even when the changed farm practice only included the. Alternation Of corn with wheat rather than the continued growing of the one crop or. The other. When in addition seeding to clover and other tame grasses has been introduced into the rotation marked increases in the yields of the grain crops have been secured. In Michigan, Indiana, and Iowa, where the feeding of beef cattle and the keeping of dairy stock has been prevalent upon this soil type for periods of 20 to 30 years, no difiiculty is experienced in maintaining the crop-producing power of the soil at an average efficiency considerably higher than the gen eral average for these States.
