Abstract:Organic amendments and nitrogen fertilization are common practices in agriculture, which have complex influences on the carbon cycle. To evaluate the effects of nitrogen‐organic carbon combination on CO2 efflux, we conducted a field incubation experiment with control, N fertilization without and with straw/biochar amendments for 20 months in a typical soil of North China Plain. CO2 efflux was measured every ~3–4 weeks, and water‐extractable organic carbon and soil microbial biomass carbon were analyzed in spri… Show more
