ALPINE SOILS CLASSIFICATION BY WORLD REFERENCE BASE:PROBLEMS AND SUGGESTIONS

Soil Classification 2004Petrozavodsk, Karelia

Some of these problems and suggestions could be discussed

during the field trip

Sesquic qualifier is used for soils having:• B horizon with high concentration of Al in soil solution• weak sesquioxide traslocation• no organic matter traslocation (i.e. not spodic colours).

The B structure is fluffy or microgranular with ochre yellow colours

Sesquic Cambisols could be seen as intergrades between Cambisols and Podzols, equivalent to Duchaufour’s sols bruns ocreux (2001) and Alocrisols ocriques (Référentiel Pédologique, 1995)

• 3 tables: STU table, PIXEL table and METADATA table

• DOM_STU added dominant STU coverage (%)

• also if non soil % > dominant STU %, dom. STU has to be considered for pixel filling in

• STU_TOT added as sum of all STU coverage (should be 100% with SUR-BARE, SUR-URB, W-BODY)

• PX-CFL, PX-AVLB, PX-SCALE, PX-OBS, PX-NPROF added to pixel table as data quality indicators

Parameters of the pixel table (SUR-BARE, SUR-URB, W-BODY) should be calculated for the whole pixel (weighted average of all STUs, including non soil bodies, of the pixel and not only for the dominant STU (as it has been done for all parameters of the dominant STU description table).

How to fill inHow to fill inMETADATA tableMETADATA table

One metadata table is required for each pilot area. Descriptions have to be as clear and complete as possible
