English to German Science Agriculture Bodenkunde

This is from a PPP on soil surfactants. The slide has the title "Consequences of soil hydrophobicity on soil water management" and this is one of the bullet points:

Non-homogenous moisture infiltration and distribution in the soil (Fingering, Tongues)

From what I could find on the internet, this relates to how the water distributes itself in the soil, i.e. it forms fingers or tongues, but I have problems finding the German equivalents. Would it be alright to simply say "Bildung von Fingern oder Zungen" or are there any more specialized terms in German?

Thanks for your help, as always!
