Ah horizons and Chernozemic order
Fragment of a discussion from Course talk:APBI200/Archive/2015-16WT2
Yes, it has to be thicker than 10 cm and they also have to specify characteristics such as base saturation higher than 80% for it to be a chernozemic Ah and therefore a Chernozem, because that is not specified, the soil in this example is a Brunisol.
Cool, thanks for the answer
