Biofunctool®: A new framework to assess the impact of land management on soil quality. Part B: Investigating the impact of land management of rubber plantations on soil quality with the Biofunctool® index

•A new soil quality index aggregating the set of Biofunctool® indicators was created.•The Biofunctool® index was applied in rubber tree-based cropping systems.•The Biofunctool® index proved to be sensitive to land uses and management practices.•The Biofunctool® index proved to be robust against various pedo-climatic contexts.•The Biofunctool® index allows to characterize a gradient of soil disturbance.
