Alfalfa is not grown as generally in Iowa as its value warrants. During the past few years, interest in the crop has increased until we now have something like 30,000 acres of it in the state, but its merit calls for a much larger acreage. Alfalfa can be grown successfully on nearly all Iowa soils. Furthermore, when measured by the four factors which determine the value of a crop in any locality, alfalfa must be considered favorably. These are:
1. The success with which it can be grown.
2. Yield per acre and money value of the product.
3. Food value for consumption on the farm.
4. Value as a soil builder.
