Like perlite, vermiculite is an effective soil conditioner that can loosen compacted soil, provide drainage, and hold three to four times its weight in water. But—and this is an important but —vermiculite is more compressible and less porous than perlite, giving vermiculite higher water-holding capacity when it's used as a planting medium.
Vermiculite is used for moisture retention and is often found in soil mixes made for vegetables (even root crops), tropical plants, or in those that offer moisture control. Unless a plant needs dry soil, you can assume that most plants will …

When vermiculite is heated to very high temperatures, it expands into long strands resembling small worms. Vermiculite is lightweight, non-toxic and sterile and does not deteriorate over time. It has a neutral pH. It's used in the building industry, the car industry and in packaging. For use in horticulture, it's sold as lightweight, absorbent ...
Figure 11.28-1 is a process flow diagram for vermiculite processing. Crude ore from open-pit mines is brought to the mill by truck and is loaded onto outdoor stockpiles. Primary processing consists of screening the raw material to remove the waste rock greater than 1.6 centimeters (cm) (5/8 inch [in.]) and returning the raw ore to stockpiles.
Key Takeaways: – Vermiculite is a hydrous phyllosilicate mineral that expands when heated. – It is commonly used as an insulating material, in gardening, and in construction. – Vermiculite improves insulation efficiency, retains moisture in soil, and reduces the weight of construction materials.
Last updated on May 11, 2023. Vermiculite is the mineralogical name given to hydrated laminar magnesium-aluminum-iron silicate that resembles mica in appearance. All …
Vermiculite is a lesser-known product that was typically used as attic insulation in homes built between the 1940s-1980s. It is a naturally occurring compound, with light-weight and fire-resistant characteristics. …

Vermiculite pot trial on selected bacterial strains in three different vegetable crops. We used eight bacterial strains with high IAA production abilities to test growth changes in pak choy and sweet pepper planted in vermiculite (size 2) pots. To simplify the growth environment, we used vermiculite and not the soil sampled from the onion field.
2015:174:Millette. Microscope, Vol 63:2 p.59-75. Millette, Compton. Abstract: There is general agreement that a negative finding using the usual bulk microscope analysis for building materials without any pre-treatment of the vermiculite is not reliable.
Mix Vermiculite with your lawn seed for newly seeded lawns to promote seed germination at a ratio of 3 cubic feet of Vermiculite to 100 square feet of lawn seed. Follow with an additional ¼ inch coverage of Vermiculite and water the area lightly. Overwinter your root crops and bulbs in Vermiculite.
Fill in with a mix of vermiculite and the removed topsoil.
