However, no study of the long-term effect of rubber plantations on soil biodiversity has been carried out yet. This study aimed to assess the long-term impact of continuous rubber monocropping on soil biodiversity, focusing on soil macrofauna and nematode diversity. Three successive rubber rotations at young and old ages were compared with the adjacent forest in Suratthani province, Thailand. Soil biodiversity quality index was calculated from a set of indicators which were combined into a single score to present a functional assessment of the gradient of disturbance. The results showed three negative effects on soil biodiversity (i) the biodiversity quality index immediately declined after deforestation (ii) the old age rubber plantations had a lower soil biodiversity as the nematodes were a main driver of diversity in the young plantation, and (iii) similarly, for the soil chemical properties, the long-term effect of rubber chronosequence evidenced deterioration in the third rotation. Therefore, two rotations of rubber plantation (around 50 years) seemed to be the maximum length of rubber monocropping in terms of soil biodiversity recovery. specialized Rubber (Hevea brasiliensis) monocropping soil biodiversity macrofauna nematode THAILANDE 074 076 72 1 612-622 2022 0906-4710 https://www.documentation.ird.fr/hor/fdi:010084339 10.1080/09064710.2022.2034930 0906-4710 [F B010084339] https://www.documentation.ird.fr/hor/fdi:010084339 https://www.documentation.ird.fr/intranet/publi/2022-04/010084339.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-04-06 2025-02-24 fdi:010084339 fre
