%X Changes produced by fire on soils depends on several factors (vegetation, soil type, temperature, etc.). Here we study the influence of fire on a gypsiferous forest soil located northwest of the city of Zaragoza. Six blocks of undisturbed soil were collected and burned under laboratory conditions reaching 272.9 ¡À 21.7 oC at 1cm depth. The fire caused significant differences (p <0.05) in all studied parameters from the O horizon and in the first centimeter of the Ah horizon. No significant differences (p <0.05) for any parameters below this depth were observed. The O horizon, strongly hydrophobic, became hydrophilic after burning. Burning induced a loss of 3.14 Mg organic carbon/ha, less than half of the values   reported for other soils with mollic horizon (8.3 Mg/ha). In our soil, the loss is due to a 53.8% in the O horizon by 35.8% in the first centimeter of the Ah, and only 10.4% is lost deeper.
