H.  aComparative classification of some deep, well-drained red clay soils of Mozambique.  aWageningen: ISRICc1987  a61 p.  a(ISRIC. Technical Paper, 16).  aClassification according to Soil Taxonomy and FAO-Unesco systems of deep, well drained red clay soils is problematic in many East African countries.  This can be  in first instance contributed to the uncompleteness of necessary morphological  and analytical data.  Therefore six soils profiles have been sent to ISRIC for monolith preparation and physical, chemical, mineralogical and micromorphological  analysis, according to required  methodology. With  these data  classification appeared to be still problematic.  To tes this, all available information of the six profiles have been sent to twenty expert soil scientists, wich were requested to classify these soils.  The classification results and additional observation on these soils of eighteen experts are presented and studied in this paper. The variation in results indicates an acute first taxonomic  level problem in both systems. Main causes of this variation are the still subjective assessment of diagnostic horizons and  - criteria, and inconsistencies in the keying procedure.  asoil taxonomy  aSolo  aClassificação comparativa  aFAO-Unesco  aMoçambique
