Soils as Generators and Sinks of Inorganic Carbon in Geologic Timesses as continents drifted and collided across global climatic zones. One of the major biogeochemical systems operating in soils across geologic time is the carbonic acid system, which includes gaseous CO., dissolved CO., carbonic acid H.CO., bicarbonate HCO..., carbonate CO..., and solid-phase calc

Organic Carbon as a Major Differentiation Criterion in Soil Classification Systemse soil cover has great variation horizontally and vertically. As organic carbon is one of the most important soil constituents, governing important functions and properties of soils, it is one of the major differentiation criteria in internationally used soil classification systems, such as Soil Tax

On Soil Carbon Monitoring Networkse task is particularly challenging because soil carbon content and stocks are driven by controlling factors of disparate origins and scales. Various approaches to the establishment of SMNs are reviewed here. Frameworks for soil monitoring exist in numerous countries, especially in Europe. Although s

Evolutionary Optimization of Spatial Sampling Networks Designed for the Monitoring of Soil Organic Cned during a first-phase sampling. The study was carried out in soils of tropical crops, forests and pastures in an area of about 1,310 ha located in the foothills situated to the east of the Colombian Andes mountains. Mean soil organic carbon content in the upper 1 m in the study area was 18.9 t ha

Distribution of Soil Organic Carbon in the Conterminous United Stateseen used to formulate estimates of soil carbon stocks, and have been useful for environmental models, including plant productivity models, hydrologic models, and ecological models for studies of greenhouse gas exchange. The data were compiled by the U.S. Department of Agriculture Natural Resources C
