“…Clay, <0.002 mm; silt, 0.002-0.053 mm; CS, coarse sand (>0.20-2.00 mm); FS, fine sand (>0.053-0.20 mm); TS, total sand (>0.053-2.00 mm); PD, particle density; Cc, compression index; s p , pre-consolidation pressure; BD max , maximum bulk density; WC crit , critical water content; BD sp , BD in the preconsolidation pressure; e, void ratio; BD i and BD f ,: BD at the beginning and end of the uniaxial compaction test; DCpt, degree of compactness; WC i , soil moisture at the beginning of the uniaxial compaction test; GM, gravimetric moisture; Def., soil deformation after load application of 1200 kPa; St TOC , total organic carbon stock; St LOM , light organic matter stock; St NLOM , nitrogen in LOM stock; St CLOM , carbon in LOM stock; d.f., degrees of freedom t-test Maia et al 2008;Rangel Vasconcelos et al 2012). Degree of compactness (DCpt) expresses BD in relation to a reference density, in this case BD max , which is a more useful parameter than BD because it eliminates the effects of differences in texture and organic matter.…”
