Silvicultura de precisão aplicada ao desenvolvimento de Tectona grandis L.f. na região Sul do estado de Mato Grosso

Abstract

The knowledge of spatial and temporal variability of factors affecting the production and productivity of forest stands allows precise interventions and obtain optimum performance. The objective of this study was to apply statistical and precision forestry tools in the study of the relationship of the development of Tectona grandis (teak) with soil chemical attributes in a pure stand in Nossa Senhora do Livramento, in south of state of Mato Grosso, Brazil. Were allocated 73 permanent plots of 15 m x 30 m and obtained the diameter at 1.3 m above the ground, height total and dominant and basal area of teak, in the second year until tenth year of age, and made collections of soil samples, at 0-20 cm depth, at two and nine years, to determine the pH, phosphorus, potassium, calcium, magnesium and organic matter of soil. Subsequently, were determined correlations and spatial modeling. The statistical tools and linear canonical correlation and geostatistics of precision forestry enable the study of the effects of soil chemical attributes in the development of Tectona grandis, in a pure stand in Nossa Senhora do Livramento, in south of state of Mato Grosso, Brazil.
