These data supported the development of maps of clay, silt, and sand content and depth to layers with >50% and >90% volume of coarse fraction in Collection 3 of the MapBiomas Soil project (beta version). Each record includes spatial coordinates, the midpoint depth of the soil layer, clay, silt, sand, and coarse fraction content, and three additive log-ratios."],"keywords":["Ciências Agrárias","Ciências da Terra e do meio ambiente"],"license":"http://creativecommons.org/licenses/by/4.0","includedInDataCatalog":{"@type":"DataCatalog","name":"SoilData","url":"http://repositorio.soildata.mapbiomas.org"},"publisher":{"@type":"Organization","name":"SoilData"},"provider":{"@type":"Organization","name":"SoilData"},"spatialCoverage":["Brasil"],"distribution":[{"@type":"DataDownload","name":"c3_soildata_psd_modeling.tab","fileFormat":"text/tab-separated-values","contentSize":6592118,"description":"Soil particle-size data used for spatial modeling"},{"@type":"DataDownload","name":"c3_soildata_psd_platform.tab","fileFormat":"text/tab-separated-values","contentSize":10410757,"description":"Soil data (gravimetric content of clay, silt, sand, and coarse fragments) for visualization in the SoilData Platform"}]}
