Abstract<\/h2>\n
\n

A growing demand for renewable carbon (C) has led to intensified forest management resulting in the use of forest residues (e.g. canopy<\/a>, bark or litter<\/a> layer) as energy sources with potential modifications of soil properties<\/a> and tree productivity. Because microbes<\/a> mediate the recycling<\/a> of C and nutrients sequestered in organic matter, we investigated the effects of organic matter (OM) removal on soil properties, root surfaces, microbial functions and abundance using a new observational forest network. We compared leaf litter<\/a> and logging residue removal plots to reference plots in six beech<\/a> forests located in the northern half of France. After three consecutive years of OM removal, C and nitrogen (N) pools were not affected, but OM exportation decreased the cation exchange capacity<\/a> and available phosphorus (P) pool by respectively 12% and 30% in the topsoil<\/a> (0\u20135\u202fcm depth). Fine root<\/a> surface area significantly increased by 21% in the subsoil<\/a> (5\u201310\u202fcm depth) in response to OM removal. Enzymatic activities<\/a> involved in N and P mobilisation decreased from 12 to 38% with the manipulation of OM. Community-level profiling (CLPP) based on BIOLOG approach revealed that the metabolic potential of the microbial community<\/a> strongly decreased in response to OM removal. Our results indicated that intensive forestry could affect microbial functions implicated in nutrients mobilisation. We demonstrated that soil organic matter<\/a> (SOM) content is a predictor of microbial functions resistance to forest residue removal. We recommend that intensive forestry should be reduced or limited in beech forests characterised by low soil OM contents.<\/span><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
