Tangelhumus in the Alps / Baier, R., E. Kolb How to place Tangel in the scheme of humus forms? • Tangel is characterized by shallow/lacking Ah horizons. • Tangel is dominated by arthropodes. Lumbricides participation is of minor importance. In an Amphi arthropodes (Oh) and Lumbricides (Ah) are important. From: Katzensteiner, K., H. Hager, M. Englisch, 2005. Main humus forms: stages of high probability in the continuum of organic matter decay. Conclusion: Tangel is no Amphi due to lacking „twin“ characteristics.
