TEXT-SRF-DOM: Dominant surface textural class of the STU

A Soil Typological Unit (STU) can have surface textures that fall in two different textural classes. The secondary surface textural class (TXSRFSE) is used to indicate the surface texture less extensive than the dominant one. Together the TXSRFDO and the TXSRFSE (Sec.surface text.class) attributes describe the lateral variability of the surface horizon texture within the STU. If there is no such variability or if information is unavailable, then the value of TXSRFDO must also be entered for TXSRFSE .

The list of authorised codes and their corresponding meanings is given in the following table:

TEXT-SRF-DOM: Dominant surface textural class of the STU
Code Value
0 No information
9 No mineral texture (Peat soils)
1 Coarse (18% < clay and > 65% sand)
2 Medium (18% < clay < 35% and >= 15% sand, or 18% <
clay and 15% < sand < 65%)
3 Medium fine (< 35% clay and < 15% sand)
4 Fine (35% < clay < 60%)
5 Very fine (clay > 60 %)
