| Figure 4 Effects of soil fauna on microbial respiration of horse manure (a, c) and cow manure (b, d) during one year of manure decomposition. CK, soil only, without manure; T0, manure addition + 0.425 mm isolation net (excluding dung beetles (dung dwelling and burrowing types) and medium-sized soil animals); T1, manure addition + 1 mm isolation net (excluding Dung beetles only); T2, dung addition + 2 mm screen (excluding burrowing dung beetles); T3, only dung addition (soil animals were not excluded). Post-hoc comparisons were performed using the Duncan test, and * indicates significant differences among different treatments (P < 0.05). |
| Fig. 4 Microbial respiration (μmol·m?2·s?1) from the mesocosms that contain dung and soil (a: horse, b: cattle) and soil only [after horse dung (c) and cattle dung (d) is removed] under different soil fauna treatments over a 1-year period. CK, Soil only, no dung nor soil fauna; T0, Dung pat covered with a wire-mesh-cage of 0.425 mm holes (excluding dung beetles and soil meso-fauna); T1, Dung pat covered with a wire-mesh-cage of 1 mm holes (excluding dung beetles); T2, Dung pat covered with a wire-mesh-cage of 2 mm holes (excluding tunneler dung beetle); T3, Exposed dung (with no exclusion of soil fauna). The significant differences between treatments at P < 0.05 are denoted using * (one-way ANOVA with Duncan’s multiple-range tests for post hoc comparisons). |
