Effect of Selected Extinguishing Agents on Organic Carbon and Nutrients Leaching from Burned Soil

The aim of this work is to determine the effect of selected extinguishing agents - water and Pyrocool B on the organic carbon and nutrients leaching from burned soil in laboratory conditions. The simulation of fire was performed in a laboratory oven by exposing the samples of soil to the temperatures from 100 oC to 600 oC and constant time of 60 minutes. After that, hot or cold burned soil was extinguished by extinguishing agents. Subsequently the suppression of thermally influenced soil was carried out, as well as the chemical analysis of total organic carbon and chosen soil nutrients in the extract of soil. To determine the carbon, nitrogen and phosphorus substances are used with conventional chemical laboratory methods.
