Question

soil layer where leaf litter decays​

Answer 1

Answer:

Humus composes the bulk of organic matter in the lower soil profile. The decline of nutrient ratios is also a function of decomposition of litterfall (i.e. as litterfall decomposes, more nutrients enter the soil below and the litter will have a lower nutrient ratio).
