Elaboração e comparação de mapas de distribuição de elementos químicos do solo por meios de técnicas geoestatísticas

Abstract

The present work aimed to make a comparison between pre-existing fertility maps of an agricultural area, with maps constructed using resources of geostatistics. We compared the maps of the elements phosphorus and potassium and created a map for the chemical element aluminum, from the information obtained in a chemical analysis of soil. This study found that there were many differences in the representations of the concentrations of the elements present in the soil, due to the fact that the samples do not give adequate spatial dependence.
