A new LandscapeDNDC biogeochemical module to predict CH4 and N2O emissions from lowland rice and upland cropping systems

Nitrous oxide and methane emissions from a subtropical rice–rapeseed rotation system in China: A 3-year field case study

“…3a). Such seasonal patterns of CH 4 emission have been well explained by the fluctuations of soil oxidationreduction conditions regulated by floodwater depth (Kraus et al, 2015;Minamikawa and Sakai, 2005;Towprayoon et al, 2005;Zou et al, 2005a), which was also determinedin our current study (Table 2). For example, during mid-season drainage, CH 4 emissions hardly rebounded to the high level observed at continuous flooding before mid-season drainage (Fig.…”

Comparison of the DNDC, LandscapeDNDC and IAP-N-GAS models for simulating nitrous oxide and nitric oxide emissions from the winter wheat–summer maize rotation system

“…A variety of process-oriented biogeochemical models have been developed, such as DNDC (Li, 1992a(Li, ,b, 2007, DAYCENT (Del Grosso et al, 2005), LandscapeDNDC (Haas et al, 2012;Kraus et al, 2014) and IAP-N-GAS (Zhou et al, 2010). Different models in the DNDC family have been extensively used to simulate the release of GHGs and nitrogenous pollutants from croplands (e.g., Beheydt et al, 2007;Cui et al, 2014;Li et al, 2006), grasslands (e.g., Frolking et al, 1998;Saggar et al, 2007) and other terrestrial ecosystems (e.g., Lamers et al, 2007;Miehle et al, 2006;Stange et al, 2000).…”

“…LandscapeDNDC (hereinafter referred to as LDNDC) is a new ecosystem model that generalizes the biogeochemical processes of the cropland and grassland DNDC version (Li, 1992a(Li, ,b, 2007 and Forest-DNDC (Kesik et al, 2005;Kiese et al, 2011;Li et al, 2000;Miehle et al, 2006;Stange et al, 2000). LDNDC has been used to simulate soil GHGs emissions from croplands, grasslands and forests at local and regional scales (e.g., Chirinda et al, 2011;de Bruijn et al, 2009;Grote et al, 2009b;Haas et al, 2012;Kraus et al, 2014;Miehle et al, 2010). IAP-N-GAS is a simpler model for simulating N 2 O emissions from croplands, which performed robustly in East China (Zhou et al, 2010).…”

Estimation and mitigation of N2O emission and nitrate leaching from intensive crop cultivation in the Haean catchment, South Korea

“…The capability for simulating of biogeochemical C and N turnover and associated losses such as N 2 O and nitrate is further supported by more studies of successful LandscapeDNDC applications and earlier model versions for other arable (Chirinda et al, 2011;Haas et al, 2013;Kim et al, 2014;Kracher, 2010;Kraus et al, 2015) and forest ecosystems worldwide (Cui et al, 2014;Haas et al, 2013;Kiese et al, 2011;Werner et al, 2007), indicating that LandscapeDNDC is generally capable to be used also in the framework of up-scaling procedures from site to regional/catchment scale like the Haean catchment.…”
