Abstract
The objective of this work was to investigate the impacts of Integrated Fire Management (IFM) in an area of the Chapada dos Guimarães National Park, to understand the effects of burning, both adverse and beneficial, on the availability of P and N, and to evaluate soil pH and moisture. Samples were collected in the Chapada National Park, which is located in the Midwest region of the country, in the state of Mato Grosso, located between the geographic coordinates 15°10' and 15°30'S and 56°00' and 56°40'W is within the Cerrado Biome, presenting a great biological diversity. The chemical parameters analyzed for the study area were: pH, moisture, phosphorus (P), total nitrogen and ammonia. The results were evaluated by Tukey's test (p<0.05) to compare the means when significant. Therefore, prescribed burning can alter the chemical characteristics of the soil without depending on the depth and seasonal period that was analyzed, in which it proves that fire is capable of altering them.
