No information
No texture (histosols, ...)
Coarse (clay ≤ 18 % and sand ≥ 65 %)
Medium (18% < clay ≤ 35% and sand ≥ 15%, or clay < 18% and 15% ≤ sand <
65%)
Medium fine (clay ≤ 35 % and sand < 15 %)
Fine (35 % < clay ≤ 60 %)
Very fine (clay > 60 %)
The following profiles do not have the correct texture data in the EST_HOR (estimated horizon
database) to qualify to the required dominant surface textural class (TEXT_1). For two profiles
(IT11 and IT14) only minor corrections are needed in the texture data (only a couple of %) to fit to
the correct dominant surface textural class (marked green). This means that other data such as CEC
and water retention still would be reliable.

For three profiles (IT13, IT20 and IT21) the corrections needed are however too great. For these
profiles corrections are not carried out. However the dominant surface textural class then needs to
be altered.
Profile IT13 (former 224) has the soil type Bea-1. This means that the percentage of sand should
be 65% or above. The percentage of sand in the surface horizon is however only 43%. A correction
of 22% is considered too great since this would have an effect on other parametres such as water
retention and CEC. TEXT_1 is therefore altered to Bea-“2”.

Profile IT20 (former 231) has the soil type Lgp-3. This means that the percentage of sand should
be below 15%. The percentage of sand in the surface horizon is however 39%. A correction of 25%
is considered too great since this would have an effect on other parametres such as water retention
and CEC. TEXT_1 is therefore altered to Lgp-“2”.

CEC. TEXT_1 is therefore altered to Pl-“1”.

Other profiles where the “dominant surface textural class” (TEXT_1) is altered.
Profile IT3 (former 214): has the soil type Rc-4 while the suggested linked STU 390860 has the
soil type Rc-3. The texture values in EST_HOR need only to be altered sligtly so that the dominant
surface textural class would be classified as “3” (medium fine) instead of “4” fine. TEXT_1 is
therefore altered to Rc-“3”. The corrections are marked “turquoise” in the spreadsheet
(EST_HOR).

The corrections carried out in the EST_PROF.dbf mean the following:

Orange
Green
Turquoise
Type of Changes/corrections
Corrections had to be carried out in EST_HOR.dbf. in order to
qualify for the originally given dominant surface textural class.
The dominant surface textural class is changed because the data in
EST_HOR do not support the given dominant surface textural class.
Both the dominant surface textural class and the data in EST_HOR
are altered in order to qualify for a “new” dominant surface textural
class that can be linked to the soil map.

SMU and STU: Some numbers are given in the SMU and STU fields. Many of them are not
correct.
Groundwater depths: There are information on groundwater levels for all profiles.
Root depths: The data are very sparse
Origin of data:
1: Average of a number of profiles:
2: From a single representative profile:
3: Predictions derived from mathematical functions:
4: Predictions derived from relationships between horizons and class functions
5: Expert judgement:
There is information about the origin of the data for most horizons. The origin of the data is a mix
of all of the above methods.
