Abstract

Considering the need for information aimed at identifying and measuring the spatial relationships of edaphic factors that limit the development of teak stands, the objective of this study was to characterize and compare the spatial variability of soil chemical attributes: pH, phosphorus, potassium, calcium, magnesium, organic matter and aluminum at two and nine years old teak stand localized in State of Mato Grosso, Brazil. Plots were allocated and soil samples were collected at 0-0.2 m depth for geostatistical modeling. Spatial changes of soil chemical attributes were detected and possible fertilization and corrections of soil acidity in specific regions of the stand for the establishment of trees and their development after thinning were recommend.
