“…The classification also enables us to recognize vertical and horizontal transitions, or mosaics between the above cited sets of humipedons (Figure 2).

It was time to take stock. We modified the humipedon classification key published in 2018 to make it easier and more practical. This morpho-functional taxonomy of the topsoil (humipedon) was only available in English; we also translated it into French and Italian. A standardized morpho-functional classification of humipedons (roughly the top 30–40 cm of soil: organic and organomineral surface horizons) would allow for a better understanding of the functioning of the soil ecosystem. This paper provides the founding principles of the classification of humipedon into humus systems and forms. With the recognition of a few diagnostic horizons, all humus systems can be determined. The humus forms that make up these humus systems are revealed by measuring the thicknesses of the diagnostic horizons. In the final part of the article, several figures represent the screenshots of a mobile phone or tablet application that allows for a fast recall of the diagnostic elements of the classification in the field. The article attempts to promote a standardized classification of humipedons for a global and shared management of soil at planet level.

“…Against all odds, however, the group remained united, but encountered very often many other difficulties, for example when the various humus forms were arranged on a global scale (Zanella et al, 2018f, 2018h). It was then necessary to introduce the concept of “humus system”, comprising ecologically and functionally similar humus forms as well as creating new systems for collecting strange, unusual or never surveyed humus forms (Zanella et al, 2018f) or for those in water (Zanella et al, 2018b, 2018c, 2018d) and in strongly anthropogenics‐shaped environments (Zanella et al, 2018l).…”

Core Ideas A common humus classification system improves communication among soil scientists. A cellular phone application can be used for global soil mapping and monitoring purposes. The humus classification can be combined with different soil classification systems. The name TerrHum is an abbreviation of the words “Terrestrial” (not hydromorphic, not submerged) and “Humipedon” (organic and organic‐mineral humus horizons). With this application, it is possible to describe and classify terrestrial forest and grassland topsoils in a system published as a Special Issue entitled “Humusica 1– Terrestrial Natural Humipedons” in the journal Applied Soil Ecology. The iOS application TerrHum allows the storage of the main content of Humusica 1 on a cellular phone. Images, diagrams and simplified tables of classification may be recalled with a few touches on the screen. Humus forms, representing five humus systems, are classified based on the vertical arrangement of diagnostic horizons and their attributes. TerrHum allows accessing specific figures that are stored in a virtual cloud and can be downloaded the first time the user recalls them. Once all figures have been opened in the device, the application is ready to use, without any further internet connection. The application is in continuous evolution.
