CODING OF PROFILE DATA ATTRIBUTES

 

Profile_ID

A soil profile ID unique for the data provided. This ID will be identical with original one used in each country. Information can have maximally 20 characters, without space.

WRB_GRP

Soil group code, see APPENDIX 1

WRB_ADJ1

Soil adjective code, see APPENDIX 1

WRB_ADJ2

Soil adjective code, second one (if present), see APPENDIX 1

WRB_SPE

Soil complementary code, see APPENDIX 1

Comment

In case that WRB classification can not be provided, please give soil type identification in FAO classification.

FAO_MG

Soil Major Group code, see APPENDIX 2

FAO_UNI

Soil Unit code, see APPENDIX 2

Comments

In case that FAO (1990) soil classification can not be provided, please give soil definitions in previous FAO classifications with indication of year from which classification is (e.g. 1970, 1974).

Code_national

In case when WRB or FAO soil classification can not be provided, please give soil definitions according to National soil classification system, list of used codes with corresponding full name of soil in national classification is needed.

Profile_mat

Parent material preferably on type level. See APPENDIX 3.

Profile_obst

Reason and depth to obstacle for roots. Criteria of identification:

 

If

        toxic is the depth (cm or class) from the surface to a toxic layer. A toxic layer can result from (e.g.) low pH values and associated high concentrations of Al and heavy metals, a high salt content etc;

        lowox is the depth (cm or class) at which there is hardly any oxygen available for plant roots. This can be the result of the presence of permanent (perched) groundwater tables, of the presence of a decomposing peat layer, etc;

        rock is the depth (cm or class) at which hard bedrock is found;

        imper is the depth (cm or class) to an impermeable layer such as (e.g.) a fragipan, an iron pan, clay layers in sediments or as result of pedogenesis;

then the depth to obstacle for roots is defined as:

 

Codes for root obstracle reason:

T toxic

L lowox

R rock

I - imper

 

The following classes of depth are distinguished in the soil profile:

 

Code

Description

1

Depth to obstacle for roots 0 - 10 cm

2

Depth to obstacle for roots 10 - 25 cm

3

Depth to obstacle for roots 25 - 50 cm

4

Depth to obstacle for roots 50 - 100 cm

5

Depth to obstacle for roots > 100 cm

 

Reason and depth to obstacle for roots = Code of root obstracle reason + Class of Depth

Example: R3

Profile_sm_X

X coordinate of described soil profile information (eastern longitude). Units are degrees.centidegrees.

Profile_sm_Y

Y coordinate of described soil profile (northern latitude). Units are degrees.centidegrees.

Profile_sm_alt

Surface altitude in meters above sea level, potentially below sea level. In case below sea level minus sign characterizes this fact.

Profile_sm_depw

The annual average water table depth in decimeters. Unknown depths or absence of a water table is indicated by a minus sign: a - sign preceding any number between 1 and 99 indicates a depth deeper than the number (example: -35 indicates a water table depth deeper than 3.5 meter); -99 indicates absence of a water table.

Profile_hor

Soil horizon code of 3 max 5 characters according to FAO horizon classification.

Profile_hm_top

Starting depth of soil horizon in cm.

Profile_hm_bot

Ending depth of soil horizon in cm.

Profile_hm_clay

Clay content in %. See APPENDIX 4 for clay size definition.

Profile_hm_clay_Q1

Country, laboratory and year of analysis.

Example: NLD01_1988

-------------------------------------------

10-digit code composed from:

          3-digit ISO-code of country of the laboratory (e.g. NLD for Netherlands)

          2-digit number referring to laboratory within the country (e.g. 01 for "bedrijfslaboratorium voor Grond- en gewasonderzoek, Oosterbeek, Netherlands", national list is yet to be compiled)

          _ (underscore-mark)

          year in which analysis was done (e.g. 1988).

Profile_hm_clay_Q2

Quality estimate of analysis according to table:

 

Quality assessment Q2

Meaning

l

low quality (e.g., measurement method obscure)

m

medium quality

h

high quality (laboratory of excellent reputation, measurement according ISO-described method)

Profile_hm_silt

Silt content in %.See APPENDIX 4 for silt size determination.

Profile_hm_silt_Q1 and Profile_hm_silt_Q2

Laboratory and quality estimate as in case of clay.

Profile_hm_sand

Sand content in %. See APPENDIX 4 for sand size determination.

Profile_hm_sandQ1 and Profile_hm_sandQ2

Laboratory and quality estimate as in case of clay.

Profile_hm_stgr

Stone/gravel abundance and size. The stone/gravel abundance (volume% classes in soil matrix) and size (diameter classes) both originate from the FAO-guidelines (FAO, 1990a) and were adapted to reflect recently changed class boundaries in WRB (FAO, ISRIC and ISSS, 1998). The first character of _stgr comes from the abundance class, the second character from the size class. Example: VF, FF.

Profile_hm_om

Organic matter content (%).

Profile_hm_omQ1 and Profile_hm_omQ2

Laboratory and quality estimate as in case of clay.

Profile_hm_hum

Humus content (%). Organic Carbon x 1.724.

 

Profile_hm_omQ1 and Profile_hm_omQ2

APPENDIX 3 LIST OF PARENT MATERIALS

The list of parent materials given below has evolved from number of approximations, using experiences from several pilot projects. The current version includes for the first time a fourth level, i.e. that of the subtype. To facilitate the correlation of national geological data to the list below, the list of parent materials is preceded by a table that gives for each of the four levels in the classification the criteria used for subdivision. To allow for maximum informative value within the major classes, criteria for subdivision were different between some major classes.

APPENDIX 4 TEXTURE CLASSES

(after CEC, 1985)

The texture and gravel content classes that follow below are used only for the classification of soil bodies; for the description of soil body horizons, actual texture fractions and a more detailed classification of the coarse fraction (cf. Appendix 6, attributes sbhm_stgr, sbhe_stgr) are applied.

 

 

The following texture classes are used:

Class

Description

0

No 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

≥ 60% clay

where sand=fraction between 50 and 2000 μmeter;

silt=fraction between 2 and 50 μmeter;

clay= fraction smaller than 2 μmeter;

 

Gravel content classes are:

Class

Description

1

Low gravel content

≤ 15% gravel

2

High gravel content

> 15% gravel

where gravel=fraction < 2000 μmeter
