Abstract

The present project aims to: a) assess the potential of using indirect techniques (diffuse reflectance spectroscopy, magnetic susceptibility and x-ray fluorescence) in the characterization of iron oxides, the physical, chemical and erosion factors soil b) the mapping of specific areas of management in commercial areas from pedotransfer functions using iron oxides c) assessing the accuracy of maps of soil attributes generated by pedotransfer functions using iron oxides. Two areas will be studied, a 500 and another 1000 hectares. In each area will be enclosed a transect and a sampling grid. Mineralogical, chemical, particle size, estimation of erosion, diffuse reflectance spectroscopy, magnetic susceptibility and fluorescence spectrometry of x-rays analyzes will be performed. All attributes will be submitted to the statistical and geostatistical analyzes to assess dependence and spatial variability and multiple regressions. Pedotransfer functions are calibrated and validated for prediction of soil attributes using mostly iron oxides as predictors. Maps using the values of predicted soil attributes in the two areas will be constructed and validated for accuracy.
