"Crop systems for Arkansas that make for increased food production and increased efficiency in man labor and horse labor are described in the following pages. By the introduction of cowpeas, soybeans, and other legumes, and by second cropping, provision is made for a considerable increase in the number of crop acres that can be farmed by the average family.... In each of the cropping systems suggested the crop acreages are calculated for two men and a team, and for light, medium, and heavy soils. These systems in general apply to all of Arkansas, except the northwestern part, and some of them may be used to advantage in northern Louisiana, northeastern Texas, southeastern Oklahoma, western Tennessee, and the northern half of Mississippi." -- p.
