WebThe PyC:SOC ratio provided the best predictor of increases in CO 2 production after PyOM addition to soil. This meta-analysis highlights the importance of taking into account the amount of applied PyC in relation to SOC for designing future decomposition experiments. WebJul 15, 2024 · More frequent but lower intensity prescribed fires stimulated production of PyC contributing to a spike in soil at about 8% of SOC at 5-yearly interval of prescribed fire. PyC declined to 2% of SOC if fires were infrequent, due to decomposition and lower input of PyC from fires (Fig. 5, see Supplementary Figure S2 for absolute values).
