Fig. 1From: Organic mulching promotes soil organic carbon accumulation to deep soil layer in an urban plantation forestEffects of organic mulching on soil organic carbon fractions in the rhizosphere and bulk soil over time. Values are means ± the standard error (n = 5). SOC: soil organic carbon; DOC: dissolved organic carbon; EOC: easily-oxidised organic carbon; MBC: microbial biomass carbon; OM0: control (no mulch); OM5: 5 cm mulch; OM10: 10 cm mulch; OM20: 20 cm mulchBack to article page
