Sweet Clover on Corn Belt Farms (open access)

Sweet Clover on Corn Belt Farms

"Sweet clover is now grown successfully on many farms in the corn belt, both in rotation and as a catch crop to be plowed under. It has proved excellent for hay and pasture, and is unequaled by any other legume for soil improvement. Sweet clover may be used to good advantage for silage, and on some farms, with proper management, it is a profitable seed crop. Mixed with bluegrass, it makes a pasture of nearly double the carrying capacity of bluegrass alone. The object of this bulletin is to present details of management and of the more important farm practices followed on some of the successful corn-belt farms on which sweet clover is grown as one of the principal crops of the rotation. Cropping systems are outlined for farms of different types, and special attention is called to the three essentials of success in growing the crop -- lime, inoculation, and scarified seed." -- p. 2

Alfalfa on Corn-Belt Farms (open access)

Alfalfa on Corn-Belt Farms

"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
