This study aimed to evaluate the influence of burning windrow wood from Cerrado (Brazilian Savanna) deforestation on the spatial variability of soil chemical properties, in the field. The data were analysed by using geostatistical methods. The semivariograms for pH(H2O), pH(CaCl2), Ca, Mg and K were calculated according to spherical models, whereas the phosphorus showed a nugget effect. The cross semi-variograms showed correlations between pH(H2O) and pH(CaCl2) with other variables with spatial dependence (exchangeable Ca and Mg and available K). The spatial variability maps for the pH(H2O), pH(CaCl2), Ca, Mg and K concentrations also showed similar patterns of spatial variability, indicating that burning the vegetation after deforestation caused a well-defined spatial arrangement. Even after 20 years of use with agriculture, the spatial distribution of pH(H2O), pH(CaCl2), Ca, Mg and available K was affected by the wood windrow burning that took place during the initial deforestation. specialized Wildfire soil digital mapping soil fertility BRESIL 068 082 51 e66853 [10 p.] 2021 1517-6398 https://www.documentation.ird.fr/hor/fdi:010082268 10.1590/1983-40632021v5166853 1517-6398 [F B010082268] https://www.documentation.ird.fr/hor/fdi:010082268 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2021-08/010082268.pdf IRD - Base Horizon / Pleins textes 2021-08-31 2021-08-31 fdi:010082268 fre
