Rubber, rubber and rubber: How 75 years of successive rubber plantation rotations affect topsoil quality?

open access: yesLand Degradation & Development, 2022
AbstractRubber tree plantations (Hevea brasiliensis) cover large areas in the tropics. In historical producing regions like South Thailand, rubber has been planted by smallholders for three successive rotations lasting a total of 75 years. Despite possible consequences on topsoil, the long‐term impacts of repeated rubber plantations on soil quality ...
