From: Soil macropore structure plays divergent roles in fresh and decomposed particulate organic matter
a Gray images. b Image was segmented into POM (red part), pores (blue part) and soil matrix (yellow part). c Representative examples of fresh POM (FPOM) and decomposed POM (DPOM). d POM was classified into fresh POM (green part) and decomposed POM (brown part). e Pores were classified into surface-connected pores (red part) and isolated pores (blue part). f Distance to pores. g Pore size distributions and the pore diameter increases with brightness. h 3D morphological reconstruction showing pore-contacting POM voxels and complete pore-contacting POM.
