Tangel<strong>humus</strong> in the Alps / Baier, R., E. Kolb<br />

How to place Tangel in the scheme of<br />

<strong>humus</strong> forms?<br />

• Tangel is characterized by shallow/lacking Ah horizons.<br />

• Tangel is dominated by arthropodes. Lumbricides participation is of<br />

minor importance.<br />

In an Amphi arthropodes (Oh) and Lumbricides (Ah) are important.<br />

From: Katzensteiner, K., H. Hager, M. Englisch, 2005.<br />

Main <strong>humus</strong> forms: stages of<br />

high probability in the continuum<br />

of organic matter decay.<br />

Conclusion: Tangel is no Amphi due to lacking „twin“ characteristics.
