Abstract

Three levels of phosphorus (0.0, 16.0 and 32,0 ppm), boron (0.0, 2.0 and 4.0 ppm), zinc (0.0, 3.0 and 6.0 ppm) and two levels of lime (0.0 and 6.0 gr. CaCO3+2.5gr,MgCO3) were applied to 8.0 kg of an Orthorx soil, originated from a "Cerrado" area from Itirapina (SP), Brazil. A factorial experiment, consisting of 3³ x 2 with two replications was conducted in a green-house at Piracicaba (SP), Brazil. The application of boron and zinc increased the concentration of these elements in the plant tissues. The application of 2.0 ppm and 4.0 ppm of boron to the soil was toxic for the Eucalyptus plants. The application of lime decreased the concentration of zinc, in the plant tissues.
