In paper "Fine root vertical-seasonal distribution of Robinia pseudoacacia in relation to abiotic factors in a chronosequence in coastal saline alkali land of the Yellow River Delta, China", FRB, FRL, FRSA, SWC and soil nutrients increased, while SRL and SSC decreased with increasing stand age. Vertically, fine roots were concentrated in a 0–20 cm soil layer. SRL, SWC and SSC increased, while soil nutrients decreased with increasing soil depth. |
