In the present study, we used sugarcane biomass derived mulch
(0.5% w/w, a relatively labile source of C compared to native SOM)
in combination with lime (0.46 and 0.92% w/w) to determine the
priming effects on organic C in an acidic soil. SOM in coarse-textured
soils is more vulnerable to environmental disturbances due to the reduced
potential for SOC stabilization in aggregates or organo-mineral
complexes (Creamer et al., 2013).
