From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

Report discussing the efforts of the Farmers' Cooperative Demonstration Work, which consists of "(1) the demonstration of improved methods of agriculture in the weevil-infected districts [...] and (2) the extension of the same principles to other Southern States beyond the range of weevil infestation." (p. 6) Congress created the organization in 1904 to assist with relief efforts.

"This paper is descriptive of the improvement of an area of poor land by growing ordinary field crops under a system of farm management which aims at the incorporation of liberal amounts of organic matter in the soil as the chief factor in maintaining fertility and increased crop yields -- a practice which can not be too frequently brought to the attention of farmers. This system has produced greater returns to the farmer who practices it than any other system in use in his locality and will serve as an object lesson to many small farmers in all parts of the country." -- p. 2

"The principal cotton diseases which cause damage in the Southern States are described and illustrated in the following pages and the best-known methods of controlling them are described." -- p. 3. Diseases discussed include wilt, root knot, anthracnose, bacterial blight, shedding of bolls, rust, Texas root rot, and other minor diseases.

Report discussing the destructive effects of the Southern pine beetle on pine forests in the southern United States. To prevent spread of the disease, infested trees should be located between November and March and destroyed. Methods for locating infested trees and destroying them are explained in detail.

Report discussing the Mexican bean beetle, which is the most serious insect enemy of beans in parts of the United States. Although it has long been present in the southwestern United States, it has recently spread to the Southeast and destroyed much of the bean crop there. This bulletin describes the beetle's life cycle and different control measures, including spraying and dusting with insecticides.

Report discussing fall-sown grain crops in the southern United States, which serve several purposes during the winter: they provide cover for land, forage for livestock, and improve soils through crop rotation. Best practices for cultivation of a winter grain crop are discussed, especially with regard to sowing methods.

This report discusses the roundheaded apple-tree borer, an insect in the eastern and midwestern United States that, in its larval stage, destroys the bark and wood of apple trees. Several methods of control are discussed, including worming, paints and washes, and sprays.Apple-tree borers.

This report discusses the challenges of growing hay in the southern United States and practices farmers can use to successfully grow their own hay crops there. Details specific crops for hay production.

This report discusses strawberry cultivation in the southern United States, especially with regard to field location, soil and climate requirements, fertilizers, harvesting, varieties, and strawberry by-products

Report discussing best practices for growing winter wheat in the eastern United States. Topics discussed include soils adapted to wheat cultivation, fertilizers, seed selection and preparation, and crop rotation.

Revised edition. Report discussing best practices for growing winter wheat in the eastern United States. Topics discussed include soils adapted to wheat cultivation, fertilizers, seed selection and preparation, and crop rotation.

Report discussing the status of hog raising in the southern United States. Topics discussed include sows, corn feeds, supplements to corn in feeds, and different breeds of swine.

Report discussing the status of hog raising in the southern United States. Topics discussed include sows, corn feeds, and supplements to corn in feeds.

Report discussing the origination and purpose of the Farmers' Cooperative Demonstration Work. The agency is primarily tasked with developing methods to control the spread of the Mexican cotton boll weevil, but it researches cultivation techniques for other crops as well, particularly corn and cowpea. This report summarizes the agency's preliminary findings.

"The growing of winter grains is an important part of the diversification of crops in the South. Winter oats is one of the best of the winter grains for general use, but under ordinary methods of culture the crop frequently winterkills or returns unsatisfactory yields. Methods are described in this bulletin by which the loss from winterkilling may be largely obviated and the yields materially increased." -- p. 2

"The cowpea is the most valuable legume for the Southern States and its use would be much more extensive were it not for the relatively high price of the seed, most of which is still picked by hand. Particular attention is therefore given to the matter of harvesting seed by machinery now in very successful use in several communities. These methods are so far perfected that the cowpea seed crop should receive much greater attention in favorable localities." -- p. 5. This bulletin also discusses the use of cowpeas for hay, seed mixtures of cowpeas and other crops, the nutritional value of cowpeas in animal feeds, growing practices, and the several different varieties of cowpea.

This report discusses the cultivation of bur clover, which is an annual legume that serves as a winter cover crop and as pasturage. The best practices for and uses of bur clover are discussed in detail.

This bulletin discusses ways that soybeans may be used in systems of farming in the Cotton Belt of the United States. Soybeans are a legume that may be used as a fertilizer, livestock feed, oil, or human food.

This bulletin describes Bermuda grass, a plant that is both highly valuable to pastures and also invasive in the southern United States, and gives suggestions for its control. Possible methods for eradication include the strategic use of shade, winterkilling, fallowing, hog grazing, and tilling practices.

"Of all corn pests in the South one of the most serious is the larva, or young, of the 12-spotted cucumber beetle -- the so-called southern corn rootworm. True to its name, it feeds on the roots, but in young corn it also drills a small hole in the stem just above the first circle of roots, boring out the crown and killing the bud.... Progressive farming methods, as described in this bulletin, will reduce the ravages of this insect. Burn over waste places to destroy dead grass, weeds, and rubbish in which the beetles winter. If possible, avoid planting corn in fields which contained corn the year before. Enrich the soil by planting legumes so that the corn will have a better chance of recovering from rootworm injury. Protect the bobwhite. This bird destroys many beetles of the rootworm. By careful observations, extending over a period of years, find out the dates between which the rooworm does the most damage; then time your planting so that it will fall either before or after these dates, taking into consideration, of course, other important factors in crop production." -- p. 2

This bulletin describes how farmers in the southern United States can cultivate pastures for hogs using forage crops. Among the crops recommended are corn, sorghum, winter grains, alfalfa, several varieties of clover and beans, cowpeas, peanuts, chufas, sweet potatoes, mangels, and rape.
