چکیده انگلیسی
After two years from compost application, the SOC stock increased in all plots, by +1.8, +2.3 and +4.9â¯Mgâ¯Câ¯haâ1 for Cp0, Cp15 and Cp30 respectively, compared to the initial stock of 36.8â¯Mgâ¯haâ1. The effect of different ASCs termination and ASCâ¯Ãâ¯compost interaction was not statistically significant. The RothC10N model was used to predict the effect of ASCs (NoASCs, FB and GMB) and Cp doses in a 20â¯years period. Predictions of the calibrated and validated RothC10N model showed that SOC change in 20â¯years was negative in the scenario with no ASCs-no compost (NoASC Cp0), where the C inputs were not sufficient to offset C losses, whereas positive values were predicted for all the other scenarios. The average values of predicted C stock change in 20â¯years were 3.8, 13.3 and 19.8â¯Mgâ¯Câ¯haâ1 for NoASC, FB, and GMB respectively and 8.2. 12.2 and 16.5â¯Mgâ¯Câ¯haâ1. for Cp0, Cp15 and Cp30. Both field experiment and model showed that the green manure of ASC and compost application represent a valid option in terms of carbon sequestration increase. RothC10N model can be used successfully as a tool to compare the C sequestration potential of alternative agronomic practices.
