Harmonized World Soil Database (version 1.0) 9 . Harmonized World Soil Database (HWSD) Soil information, from the global to the local scale, has often been the one missing biophysical information layer, the absence of which has added to the uncertainties of predicting potentials and constraints for food and fiber production. National Laboratory (ORNL) Distributed Active Archive Center (DAAC). The most popular versions among the software users are 1.2, 1.1 and 1.0. On the basis of soil parameters provided by the Harmonized World Soil Database (HWSD) seven key soil qualities important for crop production have been derived, namely: nutrient availability, nutrient retention capacity, rooting conditions, oxygen availability to roots, excess salts, toxicities, and workability. I was successful in connecting the Microsoft Access database provided by HWSD to ArcGIS Desktop 10.1 using Build Raster Attribute Table tool. grid cell to the other attributes.The HWSD v1.2 attribute lookup table is The soil composition is expressed by the attribute table of the HWSD, which provides for each soil mapping unit the component soil types as well as estimated percentages of occurrence. from Oak Ridge National Laboratory Distributed Active Archive Center, Oak Ridge, Soil information, from the global to the local scale, has often been the one missing biophysical information layer, the absence of which has added to the uncertainties of predicting potentials and constraints for food and fiber production. Harmonized World Soil Database (version 1.0) 1 Harmonized World Soil Database 1. "The Land Use Change and Agricultural Program" (LUC) of the "International Institute for Applied System Analysis" (IIASA) and the "Food and Agrigultural Organization of the United Nations" (FAO) have developed a new substantial "Harmonized World Soil Database" (HWSD). R. Hiederer, M. Kochy 2012. 前言. Soc. Petric phase: The petric phase marks soils with a layer consisting of 40 percent or more, by volume, or that are high in organic matter content (Histosols). E-mail: uso@daac.ornl.gov The Harmonized World Soil Database is produced in a uniform raster format with a 30arcsec resolution (1km). You can run this free PC software on Windows XP/7/8/10 32-bit. They regridded the SOC pools from the 30 arc sec HWSD grid to the CLM grid cell using an area-weighted, mass-conserving algorithm. Few missing data values exist in the source databases. Users have to keep in mind  that the soil variability shown in the HWSD is often more related to the different scales and levels of detail of the component national maps that contributed to the HWSD than to the real complexity of soil patterns in different areas . Harmonized World Soil Database (HWSD) Soil information, from the global to the local scale, has often been the one missing biophysical information layer, the absence of which has added to the uncertainties of predicting potentials and constraints for food and fiber production. The component soil types are typified by the soil classification units of either the, 1974 Legend  of the FAO Soil Map of the World, 1990 Revised  Legend of the Soil Map of the World, Regional Office for Europe and Central Asia, Regional Office for Latin America and the Caribbean, Regional Office for the Near East and North Africa.

Global Soil Organic Carbon Estimates and the Harmonized World Soil Database Global estimates of soil organic carbon stocks have been produced in the past to support the calculation of potential emissions of CO2 from the soil under scenarios of change land use/cover and climatic conditions (IPCC, 2006), but very few global estimates are presented as spatial data. Our built-in antivirus checked this download and rated it as 100% safe. More details can be found in Wieder et al. R interface to the Harmonized World Soil Database. ISSOIL indicates whether the soil mapping unit is a soil (1) or non-soil (0), MU_GLOBAL provides a link from the 2014. Topsoil and subsoil carbon content (T_C and S_C) are based on the carbon content of the dominant soil type in each regridded cell rather than a weighted average. ORNL DAAC: This data set describes select global soil parameters from the Harmonized World Soil Database (HWSD) v1.2, including additional calculated parameters such as area weighted soil organic carbon (kg C per m2), as high resolution NetCDF files. They then calculated the SOC by multiplying the soil organic C (%) by bulk density (kilogram per cubic meter) and soil depth for each soil mapping unit. 1 = 150 mm water per m of the soil unit, 2 = 125 mm, 3 = 100 mm, 4 = 75 mm, 5 = 50 mm, 6 = 15 mm, 7 = 0 mm. Five major pH classes are considered here that have specific agronomic significance: pH < 4.5 Extremely acid soils include Acid Sulfate Soils (Mangrove soils, cat clays). 前言. Few missing data values exist in the source databases.
