Distinct Surface and Deep Soil C, N, and Microbial Responses to Long-Term Pasture Management in Two Sub-Tropical Grasslands

摘要: • Dramatic increase in grassland management intensity (fertilization, land-use conversion, vegetation shifts, etc.) have led to changes in ecosystem functioning, including C and N storage and cycling; the quantification of which is challenging because of complex environmental interactions (eg, with seasons, soil types, vegetation, grazing intensity, climate).
