Vermicompost vs. Vermiculite — What's the Difference?
By Tayyaba Rehman — Updated on January 11, 2024
Vermicompost is organic compost made through earthworm digestion, rich in nutrients for soil. Vermiculite is a mineral used for aeration and water retention in soil.

Key Differences
Vermicompost is a type of compost produced by earthworms digesting organic matter, resulting in a nutrient-rich soil amendment. In contrast, Vermiculite is a naturally occurring mineral, expanded through heating, used to improve soil aeration and moisture retention.
While Vermicompost enhances soil fertility by adding beneficial microorganisms and nutrients, Vermiculite, being inorganic, does not contribute nutrients but aids in root growth by creating air channels.
Vermicompost is beneficial for improving soil structure and enhancing microbial activity, thus boosting plant growth. Conversely, Vermiculite is non-nutritive but helps in maintaining consistent soil moisture levels and temperature.
The application of Vermicompost is primarily for nutrient supply and enhancing soil organic matter. In contrast, Vermiculite is used for seed germination and transplanting, providing a sterile medium that prevents fungal infections.
Vermicompost is best suited for organic gardening, enriching the soil with essential elements. Vermiculite, on the other hand, is ideal for hydroponic systems and as a soil amendment to prevent compaction.

Vermicompost
Vermicompost (vermi-compost) is the product of the decomposition process using various species of worms, usually red wigglers, white worms, and other earthworms, to create a mixture of decomposing vegetable or food waste, bedding materials, and vermicast. This process is called vermicomposting, while the rearing of worms for this purpose is called vermiculture.
Vermiculite
Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect.
Vermicompost
To make compost by providing organic waste as a food source to earthworms and then collecting their excrement.
Vermiculite
Any of a group of micaceous hydrated silicate minerals related to the chlorites and used in heat-expanded form as insulation and as a planting medium.
Vermicompost
Compost created in this manner.
Vermiculite
(mineral) A hydrated silicate mineral which expands on heating; it is used in insulation and as a medium for planting.
Vermicompost
To employ worms to break down organic waste into soil or humus
Vermiculite
A group of minerals having, a micaceous structure. They are hydrous silicates, derived generally from the alteration of some kind of mica. So called because the scales, when heated, open out into wormlike forms.
Vermicompost
The product of worm composting; worm castings
