Soil Erosion. LC Science Tracer Bullet.
Buydos, John F., Comp.
Soil erosion is the detachment and movement of topsoil or soil material from the upper part of the soil profile. It may occur in the form of rill, gully, sheet, or wind erosion. Agents of erosion may be water, wind, glacial ice, agricultural implements, machinery, and animals. Soil conservation measures require a thorough understanding of the mechanics of erosion processes. Runoff, slope, rain, wind, plant care, and the presence or absence of conservation measures are some of the factors which influence the rate of erosion. Erosion results in a deterioration in the quality of cropping and grazing land in addition to reduced productivity and increased expenditure for fertilizers. It is essential to control erosion in order to maintain productivity of the soil, to reduce sedimentation in streams and lakes, and to prevent further damage to the land by gullies and ditches. Some common methods of checking erosion are control of overgrazing, construction of barriers, contour trenching, and afforestation. This guide offers a selected bibliography of the literature in the Library of Congress on soil erosion. Organization of listings include: basic texts, handbooks, bibliographics, government publications, conference proceedings, reviews, abstracting and indexing services, technical reports, and other selected materials.
