Vegetation and land-use effects on soil properties and water infiltration of Andisols in Tenerife (Canary Islands, Spain)

Auteur(s) et Affiliation(s)



Description :
This work aims to ascertain the influence of modifications to land use as well as vegetation cover on the steady-state infiltration rate and associated properties of Andisols on the volcanic island of Tenerife (Canary Islands, Spain). Thirty two sites were selected in 3 categories of land use/vegetation cover (green forest, pine forest and cropped areas). Infiltration is extremely rapid under green forest but falls considerably under pine forest and in formerly cropped soils. The statistical analysis shows that the main soil properties affected by a change in land use/vegetation and which determine infiltration are soil aggregation, structural stability and, to a lesser extent, organic matter and bulk density. The results confirm the vulnerability of Andisols' soil properties and infiltration to land use modification, while also highlighting the influence of the type of forest cover present.
