The phrase "accumulation of humus" is correct and usable in written English.
It can be used in discussions related to soil science, ecology, or agriculture, particularly when describing the buildup of organic matter in soil.
Example: "The accumulation of humus in the forest floor plays a crucial role in maintaining soil fertility and supporting plant growth."
Alternatives: "build-up of humus" or "collection of humus".
Mollisols are characterized by a significant accumulation of humus in the surface horizon, or uppermost layer, which is almost always formed under native grass vegetation.
Luvisols are technically characterized by a surface accumulation of humus overlying an extensively leached layer that is nearly devoid of clay and iron-bearing minerals.
This is a weathered layer that contains an accumulation of humus (decomposed, dark-coloured, carbon-rich matter) and microbial biomass that is mixed with small-grained minerals to form aggregate structures.
The most common of these suffixes are applied to B horizons: g to denote mottling caused by waterlogging, h to denote the illuvial accumulation of humus, k to denote carbonate mineral precipitates, o to denote residual metal oxides, s to denote the illuvial accumulation of metal oxides and humus, and t to denote the accumulation of clay.
Below the surface horizon, Mollisols do not show major accumulations of humus or translocated (migrated) aluminum- and iron-bearing minerals.
A recent chronosequential study on the succession of vegetation, profile morphology, and soil properties of post-agrogenic sandy soils under self-restoration of the southern taiga zone in the European part of Russia showed that the vegetation developed towards spruce forest and the soils towards natural Podzols with an accumulation of thick raw humus layers [4].

That means, for the amount of finished compost, 20% substitution of peat and 80% agricultural use, thereof 20% of humus accumulation and 80% of humus reproduction was assumed.
Accumulation of atmospheric particles and dead microorganisms (algae) constitutes the major portion of humus.
Soil science began with the formulation of the theory of humus in 1809.
The ground surface is bare, except for a thin layer of humus and fallen leaves.
