Farm Practices That Increase Crop Yields in Kentucky and Tennessee
"In the limestone and mountain districts south of the Ohio River there is much land that has been run down by continual cropping without rotation. In some places run-down land is left to grow up in weeds, wild grasses, and brush, a practice known as 'resting' the land. Where this sort of farm management is followed farm manure is largely wasted, little or no attention is paid to green-manure crops or other means of putting humus into the soil, and crop yields are very low. However, progressive farmers throughout the region who have built up run-down lands are now getting heavy yields. In the following pages are described some of the methods by which these farmers get results by making good use of farm manure and crop refuse, using legumes and grasses in regular rotations, and applying lime and commercial fertilizers." -- p. 2

Ways of Making Southern Mountain Farms More Productive
"The southern mountain farm often produces no more than a scant living for the family. Corn is the chief crop grown. Often part of the farm lies idle, being 'rested' while corn is grown on another part year after year until the land is worn out. By growing three or more crops in rotation, including clover, the farmer will be able to produce larger crops, make more money, and keep all crop land under cultivation all the time. Cattle, hogs, and sheep will not only add to the cash income, but will help to increase the fertility of the soil, and render larger crops possible. This bulletin describes crop rotations for small mountain farms in the southern Alleghenies, and gives complete directions for starting a crop rotation that will make poor mountain land more productive." -- p. 2
