Fig. 4

Responses of net ammonification (NAR), nitrification (NNR) and mineralization rates (NMR) to throughfall reduction treatment (TRT). Soil depths of 0–10 cm (a, c, e) and 10–20 cm (b, d, f). Different lowercase letters indicate significant differences between the TRT and the control for the same soil depth and sampling period (p < 0.05). Values are mean (n = 3) ± SE
