Description:
The geographic patterns of soil water-holding capacity are important for studying the response of vegetation and water supply to climate change. his study was conducted to evaluate which dataset to use for national-scale water balance modeling. patial databases of soil properties for the contiguous USA were derived from the USDA national soil database (NATSGO) and the United Nations soil map of the world. he NATSGO data are recommended because the map unit composition was based on a statistical framework with a large sample size and it better characterized rock fragment content and soil depth.
