soil order
Fragment of a discussion from Course talk:APBI200/Archive/2014-15WT2
No, one sequence of horizons can ONLY belong to one order. The example you showed, can only be a Luvisol, since its Bt horizon is very well developed (i.e. thick) and the main soil formation process (i.e. accumulation of clay) is present in 50 cm of this soil profile. For this soil to be a Brunisol, it would not have a Bt horizon and its Btj horizon would need to be much thinner.
