• The first to fill in the exchange format in order to provide an example
• Austria-Veneto pilot areas are not cross-border
LACK OF HARMONISATION POSSIBILITIES
![Page 3: VENETO REGION PILOT AREA Silvia Obber VENETO REGION PILOT AREA Silvia Obber Osservatorio Regionale Suolo - ARPAV Ispra - February 6-7, 2006](https://reader036.vdocuments.us/reader036/viewer/2022062511/551534e555034673228b5966/html5/thumbnails/3.jpg)
• Austria-Veneto: very different environments.
High interest but low correlation possibilities
• Humus forms could have been discussed more, during all excursions (important for OC)
• Friuli-Slovenia: good examples of harmonisation. A single pilot area, already harmonised.
EXCURSIONS

• Similar interpretations of pedogenetic processes(es: Bs/Bw horizons in Lombardy or Switzerland)
• This should lead to similar classifications, with few problems of different soil classifications on the borderline (U. Wolf)

• Italy seems confident using WRB classification (no national classification)
• Countries with national classifications tend to “translate” their classifications to WRB (single WRB adjective)
CLASSIFICATION

STU-TOT (pixel table)Total STU coverage (%), sum of all STUs coverage. STU-TOT+NON SOIL should be 100%, exept for
border pixels.
Was the interpretation of the parameter the same for everyone?
Is it coherent with the 1:1M DB?
Problem: NON SOIL (SUR-BARE+SUR-URB+W-BODY) and
STU_TOT come from different DB

SUR-BARE+SUR-URB+W-BODY:
Should everybody use Corine 2000 to have the same definition of NON-Soil or should they use local sources and describe them in metadata?
Which is the source for non-soil for the 1:1M DB?

PX-CFL: Confidence level of pixel description
PX-AVLB: Soil data availability
PX-OBS: Number of total observations in the pixel
N-PROF: Number of profiles in the pixel
There is no reason not to fill in these parameters.

CO-HUM: organic carbon content of holorganic layers in the pixel (t/ha)
Is the value “0” of some pilot area for missing data or for no holorganic layers presence? (es: agricultural sites, vineyards, ecc..)

S-LOSS: Actual soil loss in the pixel (t/ha/year)
some pilot areas have filled the DB with the interval of the classes of t/ha (ES: 10-40)

STU-DOM
Dominant STU coverage (%). It should have been calculated as percentage of the STU-TOT
Was the interpretation of the parameter the same for everyone?
Is it coherent with the 1:1M DB?

TOP-DEPTH : depth of topsoil (cm)
It gives precision and accuracy to the data, it helps to characterise mountain and agricultural soils
Should bulk density and organic carbon content of TOP-DEPTH be added to check the data of 1:1M DB?

Very important to be filled in.
Has it been filled by all partners?
If not, why not?
