Abstract
The edaphic factors have been evaluated in an area of 2.68 ha in the pending NE of the “Tuña"woodland municipality of Tineo, affected by descending controlled burns of Erica and Ulexwith a yield of 1.5 ha h-1. The soil alterations to the 6, 12, 18 and 24 months after it burns, tookplace to 0-2, 2-5 and 5-10 cm of depth, showing the existence of an increment of the soilfertility. To the 6 and 12 months of the fire, clay fraction increased and sand diminished andvice versa to the 18 and 24 months of the controlled burns. The pastoral value increased 37% tothe 12 months of the burns, observing from there, a light decrease to the 24 months. Theincrease of fertility after the fire it could be taken advantage of by the vegetal cover result of theburned vegetation regrowth.
