Fig. 4. Average evolution of the total organic matter (TOM) distribution in the Van
Soest fractions for the six composting replicates (C1–C6), expressed in g 100 g1 of
initial total organic matter (TOM). The proportion of mineralised OM was calculated
from the mass balance during composting (W100, hot water soluble fraction; SOL,
soluble fraction in neutral detergent; HEM, hemicellulose-like fraction; CEL,
cellulose-like fraction; LIC, lignin-like fraction). Error bars represent the standard
deviation.
