Abstract: The fine clay (<0.1 祄) fraction of a clayey soil (Vertisol) from Sardinia (Italy) was studied by means of X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, cation exch...
Low-Charge to High-Charge Beidellite Conversion in a Vertisol from South Italy
Beidellite Smectites Vertisol

The fine silt (2? 祄) coarse clay (0.1? 祄) and fine clay (<0.1 祄) fractions of a Vertisol from South Italy were studied with X-ray diffraction. The most reactive fine clay (<0.1 祄) fraction was investi...
Optical Density of Vertisol Clay Suspensions in Relation to Sediment Volumes and Dithionite-Citrate-Bicarbonate-Extractable Iron
