3.1. Physical and chemical characteristics of the soils
The soil texture of the burned and unburned areas was
classified as clay (Table 1). Two months after the fire, the pH of
the burned soil was 0.13 units higher than that of the unburned
controls, although the difference was not significant (Table 1).
Compared to the unburned site, EC was markedly higher in the
burned soil, reaching as high as 0.30 dS m1 after the fire (Table 1).
Organic carbon varied from 32.80 to 66.60 mg g1 in the burned
soils and from 13.80 to 55.70 mg g1 in the unburned soils
(Table 1). The level of nitrogen varied from 2.93 to 4.50 mg g1 in
the burned soils and from 1.54 to 4.28 mg g1 in the unburned soils
