default_TOC_GperKG |
A numeric value. The default value is 0 g TOC per kg soil. |
It appears that NODATA values are recorded as 0s.
We convert what ‘CONUS-SOIL’ calls “bulk density” to matric density with equation 20 from Saxton et al. 2006: bulkd = matricd * (1 - rockvol) + rockvol * 2.65 If this variable is indeed “bulk density”, then equation 20 (Saxton et al. 2006) would give negative values
