VARIABILIDADE DE ATRIBUTOS EDÁFICOS EM DIFERENTES AMBIENTES DE VOÇOROCAS NO BIOMA DA MATA ATLÂNTICA: Gullies in Mar de Morros environments

The study had to evaluate and determine the spatial variability of soil chemical and physical attributes in the internal and external environment of a gullie convex pedoform. The study was conducted in the Cachimbal stream sub-basin, Pinheiral, RJ. The mapping of the area was developed from the image of the year 2017, obtained in Google Earth, with spatial resolution of 2.34 meters, being the quantitative data quantities, with a voice expression and quality (concave or convex pedoform) through digital curvature surface access model (CSEDM) with field validation. Subsequently, it was an incident intermittence, was more intense, in which samples were collected indoors and outdoors at a depth of 0-0.10 m for the evaluation of chemical and physical attributes of gullies. The tests were larger than a larger number and / or larger than the most recent geological tests, since it was not possible to verify the existence of a spatial dependence. It was seen that the chemical and physical attributes of soil spatial variability differed when compared to indoor and outdoor environments. A geostatistic has the potential to spatialize the chemical and physical attributes of the soil in degraded environments such as gullies.
