1. but under our specific conditions of nanoparticle addition in biochar-blended compost, a larger proportion of biochar could be susceptible to mineralization in the short term. Figure 6. Estimated carbon contents relative to solid-state 13 C CPMAS-NMR spectral region before and after the 60-day incubation. C3 PRE: carbon contents relative to the C3 (compost-derived) fraction before the incubation. C4 PRE: carbon contents relative to the C4 (soil-derived) fraction before the incubation. C3 SIM: simulated carbon contents relative to the C3 (compost-derived) fraction after the 60-day incubation. C4 SIM: simulated carbon contents relative to the C4 (soil-derived) fraction after the 60-day incubation. POST: Estimated carbon contents measured after the 60-day incubation.
