Última Physical attributes of a pasture soil in southeast Goiás determined by geostatistics 70 Cardoso,Gabriel G. de G.; Wanderley,Rilley C.; Souza,Mara L. C.. ABSTRACT This study aimed to evaluate the spatial dependence of physical attributes in a soil cultivated with Brachiaria grass. A 12-m regular sampling grid was established within an area of 3.500 m2. Thirty-five soil samples were collected at 0-30 cm depth for particle density, bulk density, texture and total porosity analysis. These data were evaluated using statistical methods of indicator kriging and the GS+ software. The GS+ software was used to develop three-dimensional maps and evaluate semivariograms. The spatial dependence was evaluated using experimental semivariograms. The analyzed attributes indicated the occurrence of spatial dependence when fit to the exponential model. Areas with higher porosity occurred in the regions with lower bulk... Tipo: Info:eu-repo/semantics/article Palavras-chave: Spatial variability; Management system; Kriging.
