Analysis of erosive events for a soil in the southwest of Buenos Aires Province, Argentina

In the SW of Buenos Aires Province, Argentina, wind erosion in a smooth field with no vegetation cover was measured during the April–November period, 2009.Mean wind speed (measured at 2 m high) of the 14 recorded storms was 32.5 km h−1. Nine surface collectors and 27 BSNE dust samplers, three per tower, distributed in a 1 ha-plot were used.Mass flux decreased with height, fitting to an exponential equation, and increased with distance. Near-surface mass flux (0.07 m) represented between 70% and 90% of the total transported material. Soil loss for the entire sampled period was 56.8 t ha−1.Considering that soil particle movement was greater near the surface, strategies to control wind erosion promoting the use of conservation tillage may be planned.
