This study intended to<br>conduct sampling and use geostatistics to predict the spatial variability of<br>environmental degradation indicators. The field of study was the microdrainage<br>basin of the Itacuruba creek in Itacuruba (PE). The georeferenced<br>samples were subjected to sulfuric acid to determine organic carbon,<br>iron oxide, aluminum oxide and molecular relation of ki and altitude. The<br>data were statistically analyzed where only the altitude presented normal<br>distribution and the organic carbon did not present spatial dependence,<br>which indicated it was a degraded area. The iron oxide content in the soil<br>surface is a good indicator of an environmental degradation index, and future<br>sampling may be spaced in 600 m in the Itacuruba region (PE). Geostatistics<br>is presented as an efficient, low cost predictor for studying environmental<br>degradation and monitoring.</span></p> ER -
