Fig. 4From: Temporal changes of fine root overyielding and foraging strategies in planted monoculture and mixed forestsCumulative fine root biomass along the soil profiles and the coefficients of the rooting distribution (β) for Pinus (a) and Cinnamomum (b) in the pure and mixed stands at ages of 10, 24 and 45 years. The β value indicates the degree of fine root biomass decreases with soil depthBack to article page
