Abstract-There is an increasing attention to the effects of subtropical region of China [8]. Recent studies reported that
agroforestry systems on agricultural sustainability and greenhouse contour hedgerow intercropping plays an important role in
[8]
gas emissions in recent years. We examined soil CO2 fluxes under preventing soil erosion and sustaining soil fertility .
different hedgerow pruning management practices (removed from However, not much is known about the impact of different
plots (AR), incorporated into soil (AI) and applied as mulch (AM)) in
hedgerow pruning managements on soil CO emissions, in
Vetiver-wheat intercropping system on a loamy clay soil, in 2
addition to the study of Guo et al. on characteristics of CO2
subtropical China. Some potential factors such as soil temperature, [9]
rainfall, water-filled pore space (WFPS) and crop biomass were also and N2O emissions . An improved understanding of the
