Analysis of Soil Structure Turnover with Garnet Particles and X-Ray Microtomography
Fig 2
3D rendering of a sample at a bulk density of (a) ρ = 1.1 g/cm3, (b) ρ = 1.3 g/cm3 and (c) ρ = 1.5 g/cm3.
The green circles highlight aggregates which are strongly (#1) or weakly (#2) covered with particles or pores in which detached particles gather (#3). The yellow circles highlight that photon absorption in garnet (#1) is higher than in iron-free minerals like quartz (#2). The red circles highlight in the incorporation of particles into the soil matrix in the course of compaction.
