Humusica 2, article 10: Histic humus systems and forms – Key of classification

In: Applied Soil Ecology, 2018, 122(Part 2), 154-161. This paper corresponds to an illustrated field key of classification of Histic humipedon. Vocabulary and diagnostic horizon definitions are in Humusica 2, article 9. The process of classification can follow a step by step way or simply be realised choosing the right diagnostic horizon on a table and composing the whole profile as in a game of construction. Examples of real profiles are given for comparison with the ones people can find in the field.
