Abstract

Soil pH buffer capacity was affected by the two forest remnant tree species and one pasture species.
The differences in the degree of neutraJization of the soil exchange cornplex was the main difference
between the two rernnant tree species: base cations (i.e. Ca2+ , Mg2+, K+) occupied the exchange complex in the soil associated to C. elaeagnoides, in contrast to that associated to C. eriostachys, because it was occupied by
H+ due to high nitrification rates. The pasture species has the lower pH buffer capacity and the acid strength was the main factor which controlled pH of soil solution. These results suggest that soil nutrient protection mechanisms were reduced by the pasture management, mainly associated to plant species
