| Abstract | On an attempt to explore the multivariate spatial structure of soil acidity data, the variables Calcium (Ca), Magnesium (Mg), active acidity (pH) and potential acidity (H+Al) were measured by 204 soil samples collected 0-20 depth from a 60 m regular grid on a corn/soybeans crop at Araguari-MG, Brazil. They were chemically analyzed as well. Under scope of Linear Model of Corregionalization (LMC), direct and cross variograms were modeled with a nugget effect and a spherical model at 451,28 m range, analyzing corregionalization structure range among soil acidity variables, in parallel with Principal Component Analysis (CPA). This analysis captured acidity phenomena structure in micro scale (nugget effect) with the influence divided between Ca and Mg elements and pH of this soil, given by an intense agronomical handling which was submitted to the soil over the years. On a long range the phenomenon was explained by H+Al, given by the geological influence (pedological formation). The eigenvalues of the structures modeled given by PCA show that nugget effect is an important part of the model. The model proposed estimated by cokriging was filtered, once interested on long range variability. The filtering process removes high frequencies provide by nugget effect, resulting in a more continuous map of the acidity phenomenon on this soil. |
