An adapted centrifugation procedure is proposed for the preparation of
Transmission Electron Microscopy (TEM) specimens of soil solutions. T
he centrifugation method allows to quantitatively produce non artefact
ed specimens of soil solutions in order to visualize colloids present
within the soil. The soil of interest is a well stratified Alpin Podzo
l where colloids <0.45 mu m Were studied. The complete scheme of centr
ifugation is presented in this paper. The results obtained by TEM on l
ysimeter solutions and Soil suspensions are discussed.
