Abstract

With the objective to evaluate the effects of the harvest systems of sugar cane in the evolution of the iron oxides attributes of the clay fraction, of an oxisol; the samples will be collected in the points of crossing of two meshes, with regular intervals of 10 meters, dimension of 200 x 50 meters, totalizing 126 points in each mesh. The samples will be submitted to the laboratory analyses for the iron oxides concentration and later they will be submitted to the rays x diffraction. The data will be submitted to the descriptive statistics. The analysis of the space dependence of the data will be made by means of the geoestatistics. Interpolated values through krigage will be used, together the measured values, for construction of maps of the studied attributes.
