Fifty paired plots under simulated rainfall showed that the use of a cover of straw mulch of 50% (1 mg ha −1 ) in olive orchards results in a reduction of soil erosion. An economic survey based on interviews shows that the use of straw mulch in olive plantation would cost €174.7 ha −1 , from which €54.7 ha −1 is needed for the application work, €52.3 ha −1 for the purchase cost, and €67.7 ha −1 for the transport of 20‐kg bales. The cost of the straw is 22.5% of the total income of the farmers. We found that their perception was negative about the use of straw mulch, as the tradition is to keep the soil clean from any weed or cover, except the crop. However, farmers would use it if they would be subsidized with a minimum of €267 ha −1 , which is €92 ha −1 more than the costs estimated on the basis of the surveys. We conclude that soil erosion can be controlled with the use of straw mulch but that to convince farmers to adopt this management strategy, it needs to be subsidized.
