H. Colleuille et al., PHYSICAL CRITERIA OF THE DIFFERENTIATION OF FERRALLITIC AND FERRUGINOUS TROPICAL SOILS, Comptes rendus de l'Academie des sciences. Serie II. Mecanique, physique, chimie, astronomie, 319(11), 1994, pp. 1375-1382
In a ferrallitic and ferruginous soil sequence from Basse-Casamance (S
enegal), the potential shrinkage-swelling of the clayey phase and the
aggregate size distribution can be used to detect precisely the transi
tion between the ferrallitic soils and the ferruginous soils, and lead
s to a better understanding of the consequences on the behaviour of th
e soils.
