This study presents the use of geostatistical analyses for the design of sampling schemes, focusing specially on the anisotropy impacts on the dimensioning of sample units and image generation techniques. The attribute studied was the superficial clay content, measured during November 1998 in a Typic Hapludox, in Campos Novos Paulista (SP). Spatial variability and anisotropy of clay content were determined by examining the semivariograms, which were fit to theoretical models to obtain its parameters (variogram model type, nugget, sill and […]
