This document describes the additional additions and changes released as part of the Salinity Soil Data Card, introduced in September
2002. It supplements the Soil Data Entry Handbook, 3rd edition (Milford et al. 2001). Only those attributes specific to the Salinity Soil
Data Card are described here. This supplement should be used together with the Handbook, in which the rest of the fields on the Salinity
Soil Data Card are described.
