LFH Presence

Fragment of a discussion from Course talk:APBI200

LFH horizons are ONLY present in forest ecosystems. Hence, soils that form in other type of ecosystems (eg grasslands, wetlands, tundra) will not have LFH horizons.
In real-life, on substantially disturbed forest sites, LFH horizons might not be present due to that disturbance. But we do not include those examples in the questions that are on our assignments or exams.

Why are LFH horizons only present in forest ecosystems? Is there insufficient litter for LFH horizons to form in non-forest ecosystems?

In forest ecosystems litter input is high and decomposition < input, thus litter accumulates forming LFH horizons

That makes sense, thank you!
