Translation guide
Humus refers to the dark organic material in soil formed by the decomposition of plant and animal matter. In Japanese, the most common equivalent is 腐植 (ふしょく), a technical term used in soil science and agriculture. For everyday contexts, descriptive phrases like 腐葉土 (ふようど, leaf mold) or 堆肥 (たいひ, compost) may be more appropriate depending on the specific meaning.
The dark, stable organic component of soil resulting from decomposition.
The standard scientific and agricultural term for humus. Used in textbooks, research, and technical discussions.
Humus increases soil fertility.
この地域の土壌には腐植が豊富に含まれている。

Refers to humic substances or humus content. Often used in compound terms like 腐植質土壌 (humus-rich soil).
腐植質土壌は保水性が高い。
Humus-rich soil has high water retention.
Partially or fully decomposed plant material added to soil to improve its quality.
Leaf mold; decomposed leaves used as a soil conditioner. Very common in gardening contexts. While not exactly the same as humus, it is often the closest practical equivalent when referring to adding organic matter to soil.
腐葉土を混ぜて土を改良する。
Mix in leaf mold to improve the soil.
この腐葉土は自家製です。

Compost; decomposed organic matter used as fertilizer. More general than humus, but often used when English speakers might say 'humus' in a gardening context.
Organic compost; emphasizes the organic nature, sometimes used to distinguish from chemical fertilizers.
有機堆肥を使った野菜は味が濃い。

The standard loanword for the food hummus. Note the spelling difference: English 'humus' for the food is usually spelled 'hummus', but the Japanese loanword is フムス.

This hummus is delicious with a lemony flavor.

In English, 'humus' (soil) and 'hummus' (food) are distinct, but the Japanese loanword for the food is フムス. The soil term is 腐植. Using フムス for soil would cause confusion.
In casual gardening conversations, Japanese speakers rarely use 腐植. Instead, they refer to specific materials like 腐葉土 (leaf mold), 堆肥 (compost), or バーク堆肥 (bark compost). Use 腐植 only in scientific or formal agricultural contexts.
