Forest fires are part of the natural dynamics of Mediterranean forest ecosystems. In the Mediterranean regions, the ecosystems are shaped by this disturbance that they have been subjected to for a long time. This work aimed to study the effect of fire on the superficial soil of the Pinus pinasterforest of Jijel, Northeastern Algeria. Soil samples were taken at a depth of 0–5 cm at different dates over a period of 24 months, in a diachronic mode. The following parameters have been tested: total carbon (C), total nitrogen (N), pH, cations exchange capacity (C.E.C.) and main exchangeable bases: calcium (Ca2+), magnesium (Mg2+), sodium (Na+) and potassium (K+). The results of the study showed a significant soil enrichment during the first few months after the fire; this temporary high fertility decreases with time due to ecosystem recovery, which could be interpreted as a return to the pre-fire state. |
