Description :
The aim of this work is to determine the silicophytolith content in Typical Argiudolls of the Pampean Plain, its relation with vegetal cover and its effect on pedogenesis. The AA. worked in 3 plots with different vegetal cover : grasses and shelter-belt plantations of acacia and eucalyptus. In the study area, morphological characterization and particle size distribution analysis of soils were completed, and pH and organic matter content were determined. Afforestation over the past 50 years does not affect either the morphological or the physico-chemical properties of soils.
