Alfalfa on Corn-Belt Farms

Description: "Alfalfa, on Corn Belt farms, if introduced in any considerable acreage, requires a great amount of labor at the most critical stage of the cultivation of corn. This bulletin tells how the more successful Corn Belt growers fit alfalfa into their cropping systems without interfering seriously with labor schedules. This is done in the main by speeding up the haying operations and corn cultivation by the use of labor-saving implements and more efficient methods. To some extent, the use of alfalfa for pasture serves to reduce the labor difficulties. The methods of handling the alfalfa crop that have been worked out by some of the more experienced Corn Belt growers are illustrated by several concrete examples of good management. The material for this bulletin was obtained on 235 Corn Belt farms on which alfalfa is grown successfully." -- p. 2
