Última Spatial distribution of the chemical properties of the soil and of soybean yield in the field Rev. Ciênc. Agron. Gazolla-Neto,Alexandre; Fernandes,Marciabela Correa; Vergara,Rafael de Oliveira; Gadotti,Gizele Ingrid; Villela,Francisco Amaral. ABSTRACT The aim of this study was to evaluate the spatial dependence between chemical properties of the soil and yield components in the soybean using precision farming techniques. Samples of the soil and plants were taken from georeferenced points to determine the chemical properties of the soil and the yield components. The results were submitted to Pearson correlation analysis, descriptive statistics and geostatistics. The coefficient of variation showed a wide range of distribution for the chemical attributes of the soil, with the highest indices being found for the levels of available phosphorus (102%) and potassium (72.65%). Soil pH and organic matter showed a coefficient of variation of 5.96 and 15.93% respectively. Semivariogram analysis of the...
