Here RVNC and SYNC are the runoff volume (L) and sediment yield
(g) under NC, while RVct and SYct are the runoff volume (L) and sediment
yield (g) under the calculated SM treatment.
The leaf area index (LAI) of each soil bin at different growth stage
was measured by the ACCUPAR LP-80 ceptometer (Decagon Devices,
Inc., Pullman, WA, USA).
