This instructional unit was designed to enable students, primarily at the secondary level, to (1) classify soils according to current capability classifications of the Soil Conservation Service, (2) select treatments needed for a given soil class according to current recommendations provided by the Soil Conservation Service, and (3) interpret a…

Outlined are simple activities for studying soil, which can be conducted in the schoolyard. Concepts include soil profiles, topsoil, soil sizes, making soil, erosion, slope, and water absorption. (SJL)

This environmental sourcebook contains activities focusing on the living and nonliving components of soil and their relationship to the earth's natural cycles. The materials contained in this guide are for use with youth ages ten and older and are designed to stimulate a sense of stewardship for the environment through group discussion, role…

Although soil erosion is a natural process, it has increased to the point where it far exceeds the natural formation of new soil. However, with only occasional exceptions, national agricultural and population policies have failed to take soil depletion into account. Projections of world food production always incorporate estimates of future…

Natural soil fertility is now declining on an estimated one-fifth of the world's croplands. Direct evidence of the mounting pressures on the global cropland base is seen in accelerating soil erosion, the spread of deserts, and the loss of cropland to nonfarm uses. (Author/BB)

Reported are the results of a survey of awareness, use, and attitude of Indiana secondary school agriculture and social science educators toward soil survey reports. An analysis by teaching discipline and geographic location is presented. (CW)

Research analyzed adoption of erosion control practices by farm operators in two counties in each of four states: Alabama, Missouri, Tennessee, and Washington. Analysis was based on farm survey data and technical and financial assistance information from county Soil Conservation Service (SCS) and Agricultural Stabilization and Conservation Service…

This book is written for individuals who wish to apply conservation practices, especially those of soil and water conservation, without technical assistance, to meet one's own conditions, and within his own capability to apply them. To meet these needs, the book includes a discussion and description of soil and water conservation methods for the…

Describes a technique for comparing the number of bacteria in various soil samples. The equipment and materials are readily available, and the technique is suitable for high school students. (JR)

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…

Presented are a variety of surface run-off experiments for high school students. The experiments are analogies to basic concepts about water intake, as related to water delivery, soil properties and management, floods, and conservation measures. The materials needed to perform the experiments are easily obtainable. The experiments are followed by…

Described is a slide set which is designed to illustrate the entire range of soils found in the arid regions of the earth's surface. Information on physical and chemical soil properties, soil classification, and related soil management considerations for agricultural development are included. (CW)

This book is designed for individuals who want to apply conservation practices either without or with minimal technical assistance. These individuals include students who want to practice soil/water conservation with some instructor guidance and others who want to apply the principles in their own way, to their own conditions, and within their own…

This report addresses the application of agricultural processing wastes, industrial and municipal wastes on agricultural land as both a waste management and resource recovery and reuse practice. The document emphasizes the treatment and beneficial utilization of sludge and wastewater as opposed to waste disposal. These objectives are achieved…

This booklet on gardening techniques uses methods that have been successful for other teachers. The activities are interdisciplinary and encourage positive attitudes toward proper uses for the land, and the importance of the farm or agriculture as a basic unit of modern life. (Author/RH)
