|Abstract:||Chemical and mineral analyses were performed with the objective of evaluating the content and availability of nutrients for Eucalyptus growth in forests of Rio Grande do Sul state, Brazil. The Quartzarenic Neosol presented a very simple mineralogy, with an extremely poor nutrient content. The Melanic Gleisol, Haplic Planosol and Red-Yellow Argisol revealed a low Ca and Mg content, while the Haplic Cambisol, Litholic Neosol and Red Argisol presented higher amounts of these nutrients. The data of the annual average increment (AAI) of seven-year old Eucalyptus permitted the distinction of three soil groups according to their differential attributes: the first group formed by well drained soils (AAI ≥ 46 m3/ha/year), the second group formed by waterlogged soils (AAI ≈ 40 m3/ha/year) and the third group formed by very sandy soils (AAI of 38 m3/ha/year).|
