Une \u00e9tude men\u00e9e dans des h\u00eatraies du sud de l’Italie \u00e9value l’impact du trafic des engins d’exploitation sur les propri\u00e9t\u00e9s physiques du sol et la biodiversit\u00e9 des microarthropodes, avec un suivi de la restauration sur 5 ans. Trois types de sites ont \u00e9t\u00e9 compar\u00e9s : r\u00e9cemment exploit\u00e9s (2021), exploit\u00e9s 5\u00a0ans auparavant (2017) et t\u00e9moins non perturb\u00e9s depuis plus de 40\u00a0ans. Les pr\u00e9l\u00e8vements distinguent syst\u00e9matiquement les cloisonnements d’exploitation des zones adjacentes non soumises au trafic des engins.<\/p>\n

Les r\u00e9sultats sont sans \u00e9quivoque\u00a0: imm\u00e9diatement apr\u00e8s exploitation, la densit\u00e9 apparente augmente de 19 % et la r\u00e9sistance \u00e0 la p\u00e9n\u00e9tration triple. L’indice de qualit\u00e9 biologique du sol par les microarthropodes (QBS-ar) chute de 50\u00a0% par rapport aux t\u00e9moins, ce qui t\u00e9moigne d\u2019une d\u00e9gradation \u00e9cologique significative de l’horizon superficiel.<\/p>\n

Toutefois, 5 ans apr\u00e8s les travaux, une r\u00e9cup\u00e9ration partielle est observ\u00e9e : densit\u00e9 apparente et r\u00e9sistance \u00e0 la p\u00e9n\u00e9tration diminuent respectivement de 13 et 8\u00a0%. Ces valeurs demeurent n\u00e9anmoins sup\u00e9rieures \u00e0 celles des sites t\u00e9moins, confirmant que la r\u00e9silience du sol reste incompl\u00e8te \u00e0 l’\u00e9chelle de la d\u00e9cennie.<\/p>\n

Sur le plan op\u00e9rationnel, l’\u00e9tude recommande la planification de cloisonnements permanents pour concentrer et limiter l’emprise du trafic, ainsi que l’usage de tapis de portance pour r\u00e9duire la pression au sol.<\/p>","protected":false},"excerpt":{"rendered":"
