Book Description
Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

Book Description
Soil is the basis not only for all gardening, but for all terrestrial life. No aspect of agriculture is more fundamental and important, yet we have been losing vast quantities of our finite soil resources to erosion, pollution, and development. Now back in print, this eminently sensible and wonderfully well-focused book provides essential information about one of the most significant challenges for those attempting to grow delicious organic vegetables: the creation and maintenance of healthy soil. Chapter 2, "Understanding the Soil System," is alone worth the price of admission. Gershuny and Smillie give lay readers and experts a clear explanation of subjects--soil life and nutrient cycles--that have confounded most authors. Nowhere will the reader find simpler and more coherent descriptions of key concepts including cation exchange capacity and chelation. There are other books about soil available, including Grace Gershuny's comprehensive Start with the Soil, and there are books that feature chapters on soil building. What distinguishes The Soil of Soilis the authors' concise presentation; they give readers important information, including technical essentials, without getting bogged down in scientific or quasiscientific mumbo-jumbo. In addition, useful tables list specific compost materials, green manures, and other resources that allow growers to translate into action the more general information provided by the book. The soil-building techniques featured include: Organic matter management Building and maintaining humus On-site composting Green manures and rotations Cultivation and weed control Nutrient balances and soil testing Using mineral fertilizers Planning for organic certification Updates to the 1999 edition include analysis of Proposed Rules for the National Organic Standards, and expanded recommendations for private testing services and soil-testing equipment for home gardeners and organic farmers. All of us involved in the cultivation of plants--from the backyard gardener to the largest farmer--need to help regenerate a "living soil," for only in the diversity of the soil and its creatures can we ensure the long-term health of ourselves and our environment. The Soul of Soil offers everyone a basic understanding of what soil is and what we can do to improve our own patch of it. Seen in this light, this practical handbook will be an inspiration as well.

Book Description
Guidelines for Surveying Soil and Land Resources promotes the development and implementation of consistent methods and standards for conducting soil and land resource surveys in Australia. These surveys are primarily field operations that aim to identify, describe, map and evaluate the various kinds of soil or land resources in specific areas. The advent of geographic information systems, global positioning systems, airborne gamma radiometric remote sensing, digital terrain analysis, simulation modelling, efficient statistical analysis and internet-based delivery of information has dramatically changed the scene in the past two decades. As successor to the Australian Soil and Land Survey Handbook: Guidelines for Conducting Surveys, this authoritative guide incorporates these new methods and techniques for supporting natural resource management. Soil and land resource surveyors, engineering and environmental consultants, commissioners of surveys and funding agencies will benefit from the practical information provided on how best to use the new technologies that have been developed, as will professionals in the spatial sciences such as geomorphology, ecology and hydrology.

Book Description
This Guide provides assistance to Natural Resources Conservation Service (NRCS) staff and its conservation partners to collaboratively develop Soil Quality Cards with local farmers. Partners such as Soil and Water Conservation Districts (SWCD), Cooperative Extension Service, state conservation agencies, and local groups assist in producing Cards that farmers and other land managers can use to assess soil quality on their land and implement management practices that ensure long-term soil productivity. To develop a process that enables NRCS and its conservation partners to design locally adapted Soil Quality Cards, the Soil Quality Institute worked with several university extension and research departments and enlisted the expertise of NRCS state and field staff across the country. The outcome is a participatory process through which farmers and conservationists learn together about soil quality and collaboratively develop assessment tools customized to local needs.
