Terrace Outlets and Farm Drainageways

Description: "This bulletin is a compilation of the best information now available for farmers on the construction and use of terrace outlets and the protection, improvement, and maintenance of other sloping drainageways. The term "drainageways" as used in this bulletin refers primarily to channels of surface drainage in the upper reaches of watersheds or in unit drainage basins. 'Outlet' is a more restricted term and refers only to drainageways that are provided to receive and convey the discharge from the ends of terraces. The scope of this material is limited to surface runoff-disposal measures required in upland or rolling terrain where slopes are steep enough to cause channel erosion. It does not cover surface drainage or underdrainage of flatlands where natural drainage is inadequate." -- p. ii

Cover Crops for Soil Conservation

Description: "Cover crops are crops sown or planted in thick stands for the purpose of protecting and enriching the soil.... That the use of cover crops is a most efficient means for preventing soil erosion and increasing soil fertility is well known; yet this practice is not nearly so widely and extensively followed as it should be. The kinds of cover crops that should be used and the method of utilizing them to the best advantage varies in different regions, according to climatic conditions but almost everywhere cover cropping in some form can be profitably followed." -- p. 1. The bulletin considers cover crops as either legumes or non-legumes.

Native and Adapted Grasses for Conservation of Soil and Moisture in the Great Plains and Western States

Description: "The information given in this bulletin should enable farmers in the Great Plains and Western States to select from the more common species of grasses some one or more suited to their needs [for soil and water conservation]. Common harvesting equipment and farm machinery can be adapted to the proper handling of native grasses. This brings the cost of such work within the means of most farmers." -- p. i. Among the grasses discussed are wheatgrass, buffalo grass, bluestem, grama, Bermuda grass, wild rye, hilaria, Sudan grass, bluegrass, panic grasses, dropseed, and needlegrass.

Soil Defense in the Pacific Southwest

Description: "The Pacific Southwest, as considered in this bulletin, embraces the two States -- California and Nevada. Evidences of soil and water losses are briefly touched upon, as are the factors contributing to these losses. The bulk of the bulletin deals with measures of defense that are now being employed on farms and range land within project areas of the Soil Conservation Service and in areas where members of Civilian Conservation Corps camps have been assigned to erosion-control activities." -- p. i. Some of the measures discussed include the use of cover crops, contour farming, crop rotation, subsoiling, strip cropping, and terracing.

A Study of Soil Erosion and its Control in the United States with Special Reference to Texas

Description: A study of soil erosion in the United States, especially in Texas, which brings attention to the causes of soil erosion under the existing system of farm management. The material gathered and compiled and arranged under certail main heading. Two chapters deal with present and immediate causes of erosions and their results. One full chapter takes up the history of the conservation movement and attempts to show how slow Texans have been in comparison with some of the other states of the United States. The study calls for further research, teaching of better land-use, raising awareness of soil erosion causes and conditions.

Soil Defense in the Piedmont

Description: "This bulletin deals with erosion of the soil and measures of defense which have proved successful in controlling erosion in that part of the Piedmont country lying in the five States of Virginia, the Carolinas, Georgia, and Alabama. The region is the rolling foothill country of the Appalachian Range, and extends east and south to the fall line which separates the Piedmont from the broad, gently sloping Atlantic and Gulf Coastsal Plains." -- p. ii. Measures of soil defense considered include terracing, contour tillage, strip cropping, close-growing crops in the rotation, and contour furrowing in pastures.

Estimating nonpoint source pollution in north Texas watersheds through remote sensing and geographic information systems

Description: Monitoring nonpoint source pollution in a large area is often impractical. However, estimating nonpoint pollution through use of empirical models such as the Universal Soil Loss Equation (USLE) provides a basis for identifying problem areas, and setting management priorities. The purpose of this study was to determine the feasibility of using Landsat imagery and existing geographic data to estimate the effects of land use changes on water quality in four North Texas watersheds over a twelve year period.

Wildlife Conservation Through Erosion Control in the Piedmont

Description: "Erosion has left scars on a majority of farms in the Southeast. Too poor to produce crops, the eroding spots are usually abandoned. Unless they are treated to stop further washing of the soil they grow steadily larger and continually rob the farmer of more of his land. Fortunately, soil conservation and wildlife management can be effectively combined, and otherwise worthless areas made to produce a crop of game, fur bearers, and other desirable types of wildlife. The general principles of wildlife management on the farm are described in Farmers' Bulletins 1719 and 1759. The purpose of this bulletin is to show how gullies, terrace outlets, waterways, eroding field borders, pastures, and woodlands in the Piedmont region may be protected against erosion through the use of vegetation that will also provide food and cover for wildlife." -- p. ii

Toward Soil Security on the Northern Great Plains

Description: "This bulletin deals with soil and water conservation problems which relate to agriculture of the northern Great Plains [of the United States]." -- p. i. "The major portion of this bulletin, beginning on page 18, is devoted to a discussion of the controls and cures for land misuse. These suggested practices, in the main, represent the methods of control that are now being used in the several demonstration areas of the Soil Conservation Service. The use of these practices in a few specific demonstration areas is included in the section beginning on page 47. The last section (p. 76) points out a democratic procedure whereby landowners and operators may effect a more appropriate use of the land through soil conservation districts." -- p. 2
