translate English to French: On dry to fresh sites, a decrease in the forest floor weight (−55%) accounted for significant reductions in exchangeable Ca (−55%), total Ca (−61%), and exchangeable K (−40%) pools in this layer, while reserves of both mineral layers were not affected.
Sur les stations mésiques, la coupe n'a pas eu d'impact sur les pools du sol minéral, mais la diminution de la masse de la couverture morte (− 55%) expliquait les réductions significatives des pools en Ca échangeable (−55%), Ca total (−61%) et K échangeable (−40%) de cet horizon.
