Simulations of wildfires in soil samples corresponding to two areas of the city of Quito with a different record in the occurrence of forest fires and different features moisture, organic matter, water repellency and vegetation were performed. In both zones control samples and samples withstand temperatures of fires specific medium and high intensity using an oven at GLP built to achieve maximum temperatures of 800 ° C with open doors were chosen.
Maximum temperatures in the samples at surface corresponding to the area Ungüi 371 ° C and the area of Paramo Antisana 310 ° C. Moisture losses were observed in the soils of the area moor up to 30%, while losses of soil moisture Ungüi area were up 90% from the initial moisture. The data obtained show a different behavior of soils especially in water repellency, a parameter that is intensified in some cases or destroyed in others.
The concentration of organic matter in samples Antisana and Ungüi with different values, giving higher concentration near Antisana regarding Ungüi area, taking that for combustion of this there is a direct concern to the other parameters studied (pH, electrical conductivity, density, nitrogen, organic carbon, texture, water repellency). |
