Abstract

This study aimed to evaluate the mineral nutrition of three years old Eucalyptus urophylla plantations, grown in different population densities in the following spacings: 3.0 m x 2.0 m; 3.0 m x 3.0 m; 3.0 m x 4.0 m; 3.0 m x 5.0 m; 4.0 m x 2.25 m; 6.0 m x 1.5 m; 5.0 m x 1.8 m; and 9.0 m x 1.0 m. The experiment was carried out at Bocaiuva, Minas Gerais State, Brazil. N, P, K, Ca, Mg, S, and B leaf content was evaluated at seven sampling dates. The nutrient content varied with sampling date; N, P, and K lowest levels were found in the dry period. No interaction was observed between spacing and sampling date for Mg. Lowest Ca levels occurred in December, except for 9.0 m x 1.0 m spacing. Spacing did not influence N, P, S, and B content. Independently of spacing and sampling date, N, P, S, and B leaf content did not present levels considered as deficient.

KEY-WORDS: Eucalyptus; mineral nutrition; population density; savannah.
