As an effort to apply wind erosion models, the AA. compared field wind erosion measurements carried out during 4 years in a bare soil reference plot and during 3 years in the same soil with different tillage conditions. Wind erosion was predicted with : 1) subroutines for single storm event versions of the wind erosion prediction system (WEPS) and the revised wind erosion equation (RWEQ), for which the climatic data of each single storm were used, and 2) the wind erosion equation (WEQ) for full rotation periods, for which long-term climatic records (1961-2004) were used. High plant or residue soil coverage as well as high oriented surface roughness eliminated erosion according to WEPS and RWEQ. These results indicated that WEQ can be used as a reliable prediction model for long-term predictions of wind erosion in the semi-arid pampas, even when run with limited available climatic data for this region
