Dataset Abstract:

Soil water was monitored weekly in a pasture north of Manaus in the Central Amazon region. A Diddcott neutron probe was used to measure water content to a depth of 3 meters. The pasture is located on a plateau and the deep highly weathered clay soil is an OXISOL according to USDA Soil Classification. These data were part of a PhD Thesis (2002). Please contact the author: Steven Welch <saw16@cornell.edu> Data Quality Statement: The Data Center has determined that this data set has missing or incomplete data, metadata, or other documentation resulting in diminished usability of this product. User beware. Known problems: Data file (Excel spreadsheet) does not provide adequate column descriptions or measurement/reporting units.
