Development of a soil degradation assessment tool for organic olive groves in southern Spain

Auteur(s) et Affiliation(s)



Description :
Forty-six organic olive orchards under different soil management systems were evaluated in the province of Córdoba (southern Spain) to assess the state of their soil properties and the degree of degradation of their topsoil, and the possibilities for monitoring any soil degradation risk. Three soil degradation indexes were obtained through a principal component analysis of the soil properties analyzed. Two of the indexes are basically integrative ones that can be used in relatively large surveys considering a large number of soil properties. The third index developed used only three soil properties, organic C, water stable macroaggregates, and extractable P, and has the potential to be used as a relatively easy and inexpensive screening test of soil degradation for organic olive farms in the area.
