Soil organic matter, soil pH and soil nutrient dynamics in forest stands after fire
MetadataShow full item record
Fires burn, spread and release energy. The process of burning not only helps increase the decomposition of organic matters but also causes the plant nutrients bound to vegetation and organic dead material to get into soil and inflicts changes on the physical and chemical properties of soil. Changes taken place in soils and their status over time are extremely important for the success of the vegetation that will establish on the site after fire. This study presents the results of a study conducted to monitor the changes in plant nutrients and soil’s chemical properties. In the study, soil organic matter, soil reaction (pH), salinity and soil nutrients were measured. Soil reaction, N and K slightly increased after fire and decreased gradually thereafter. Other nutrients gradually decreased after fire throughout the study period. As a result, it can be said that the effect of fires on soils in areas having little or no dead surface fuels are limited, yet important.
