The WIND-O-V field experiment: WIND erOsion in presence of sparse Vegetation

Publikováno v: INTERNATIONAL CONFERENCE ON AEOLIAN RESEARCH 2018
INTERNATIONAL CONFERENCE ON AEOLIAN RESEARCH 2018, Jun 2018, Bordeaux, France

International audience; Wind erosion in semiarid areas is a major threat for the soil productivity as it impoverishes soil in organic matters and nutrients. Compared to desert regions, these regions are characterized by sparse seasonal vegetation tha
