Title : Long-term influence of biochar on native organic carbon mineralisation in a low-carbon clayey soil
Journal : Scientific Reports
Comment : They estimate that biochar-stimulated SOC mineralisation (‘‘positive priming’’) caused a loss of 4 to 44 mgC g-1 SOC over 2.3 years in a clayey, unplanted soil (0.42% OC). They conclude that biochar stimulates native SOC mineralisation in the low-C clayey soil but that this effect decreases with time.
