What does humous mean?
Humous is an adjective meaning “of or relating to humus.” Humus is the dark, complex material formed when plant remains, microorganisms, and other organic substances gradually decompose within soil. A humous soil therefore contains a significant proportion of this biologically active material, which helps retain moisture and supplies nutrients as it breaks down further. The adjective appears in descriptions of soil horizons, garden compost, and organic matter, especially in technical, agricultural, ecological, or literary writing. It should not be confused with the closely related noun humus, which names the material itself. Although sound and soil-science discussions commonly use humus, humous remains useful when a writer needs to turn the name of the substance into an attributive modifier.
