Description :
An interdisciplinary assessment of the conservation practices on forest soils in Mexico was conducted (1) to evaluate their effectiveness in terms of soil quality indicators and (2) to use social indicators of their acceptance and execution. After 4 years of soil conservation measures in areas under common ownership, involving ditches, individual terraces or arrangement of plant material, soil indicators such as bulk density, total carbon, total nitrogen and pH in 9 sites and 54 plots showed deficiencies in soil properties involved in productivity and hydrological regulation, in comparison with the control groups. The results suggest that the conservation practices are not improving any of these functions. Social indicators revealed that the soil conservation program only encourages participation through economic stimulus. Therefore, the AA. propose new assumptions to soil conservation program, using interdisciplinary approaches.
