Soil C input–emission balanced with different FOM and water addition treatments during study period. Data are in contrast to the controls (F0P0).

Other abbreviations are same as Table 1.
C lost as CO2 (g/m2)  =  mean soil respiration of the whole period (µmol CO2 m–2 s–1) ×12 g × 1E−6 × time (s); Additional C lost as CO2 (g/m2)  =  (C lost as CO2 in other treatments) – (C lost as CO2 in F0P0); Soil C input–emission balance (g/m2)  =  (addition C lost as CO2) – (C added).
