Description :
Spatial variability of physical and chemical properties in Amazonian soils is evaluated on sites of natural rain forest and pastures of different age in the Amazon region. The sampling scheme was regionalized using transects of fifty 3 m apart each. Variables analysed were : soil bulk density| resistance to penetration| soil water content| available water| pH and extractable ions such as Ca, K, Al, P and Zn.
