Spatial correlation of soil chemical attributes with the development of teak in Mato Grosso
The objective of this study was to investigate the spatial correlations of soil chemical attributes with the development of teak (Tectona grandis) in the city of Nossa Senhora do Livramento, Mato Grosso State, Brazil. It was allocated 46 permanent plots of 15 m x 30 m. From the stand it was obtained...

| Resumo: | The objective of this study was to investigate the spatial correlations of soil chemical attributes with the development of teak (Tectona grandis) in the city of Nossa Senhora do Livramento, Mato Grosso State, Brazil. It was allocated 46 permanent plots of 15 m x 30 m. From the stand it was obtained the mean annual values of diameter at 1.3 m above the ground and total height of second to ninth years of age. Soil samples from 0 to 0.20 m depth were also obtained at the second year, to determine pH, calcium, magnesium and aluminum, phosphorus and potassium for subsequent modeling of spatial patterns by geostatistics. The diameter at 1.3 m and the total height of teak present higher spatial correlation with the chemical soil attributes pH and calcium, low spatial similarity with potassium and magnesium, absence for phosphorus and inverse relationship with aluminum. |
