Description
|
Observations on soil organic carbon (SOC) gravimetric and volumetric contents (SOCg, in g kg-1, and SOCv, in g dm-3, respectively) for 98 profiles at least 30 cm deep (1 m deep for 59 of them) in relation to soil types and land uses and management, particle size distribution down to 30 cm, and near infrared reflectance (NIR) spectra for the main soil types. This updated version includes latitude and longitude (approximated to the minute, i.e. less than 1-km grid spacing, so that fields could not be identified precisely, to preserve confidentiality). |
