ConsultaEarly soil mappers in 1923 from the Berau of Soils ( USDA ). One of the early soil surveyors for the USA’s Bureau of Soils was Hugh Hammond Bennet. During the soil mapping of Louisa County, Virginia in 1905, he was directed to investigate declining crop yields in the area. He was struck by the differences in the condition of soil under virgin
ConsultaSSURGO is the result of the work of the US Department of Agriculture’s National Cooperative Soil Survey, which has collected soils data for much of the United States. SSURGO is developed from fieldwork and analysis of aerial imagery and includes spatial data (ESRI shapefiles) and tabular data (Access databases).
ConsultaThe National Cooperative Soil Survey is a compendium of resources for many fields of study. Farmers and realtors interested in creating a soils map of a property and learning what that information means, may want
ConsultaSoil horizons from monoliths Purdue University’s Extension School created this video describing soils using “monoliths”: columns of preserved soils for teaching and
ConsultaThe National Cooperative Soil Survey (NCSS) has supported the collection of soil survey information since 1899 when texture was first recognized as a primary soil characteristic. From 1920 to 1950, the NCSS recognized more soil properties significant to farming, ranching, and forestry. In the 1950s, cooperative research with State highway
ConsultaParent material refers to the natural geology of a place and the material that forms the soil. More details on Iowa's geology can be found in the WL17a: Landforms and Geology article in this series. The material might be deposited from a flood, wind, or a glacier, or it can form from bedrock breaking down.

ConsultaThe National Cooperative Soil Survey Program (NCSS) in the United States is a nationwide partnership of federal, regional, state, and local agencies and institutions. This partnership works together to cooperatively investigate, inventory, document, classify, and interpret soils and to disseminate, publish, and promote the use of information about the

ConsultaThe National Soil Survey Handbook (NSSH) provides the standards, guidelines, definitions, policy, responsibilities, and procedures for conducting the NRCS portion of the National Cooperative Soil Survey program. The NSSH contains information on how to plan and manage soil surveys; collect, document, and interpret soil survey information; and
ConsultaThe organic material of soil, called humus, is made up of microorganisms (dead and alive), and dead animals and plants in varying stages of decay. Humus improves soil structure and provides plants with water and minerals. The inorganic material of soil consists of rock, slowly broken down into smaller particles that vary in size.

ConsultaThe objective of this research was to derive high-resolution spatial data on soil and land use data for use by dynamic simulation model of carbon fluxes from soils resulting from land use change. The soil spatial distribution was based on the revised 1:250 000 national soil map for England and Wales, the 1:250 000 national soil map for Scotland
ConsultaSoil depths in Iowa are commonly between 30 and 70 inches. Soil profiles are composed of various layers called soil horizons. The horizons form roughly parallel to the land surface under the influence of weathering, leaching, and plant and microbial activity. The character of each horizon is a result of the nature of its parent material and the
