A bentonite clay based coating will help to swell upon seeding when in contact with water.

Bentonite benefits in seed coating use

For the bentonite seed coating to be effective, the coating requires calcium bentonite as this will release the seed the moment it is wetted. The moisture will force the clay plates apart.
When necessary or required the bentonite can be coloured by the seed coating manufacturer.

Bentonite mineral origin

Bentonite is derived from volcanic ash and consists predominately of smectite minerals usually Montmorillonite. Bentonite is categorised as a sedimentary deposit containing >50% Montmorillonite which is volcanic in origin. Montmorillonite is a dioctahedral layer silicate and in sodium form swells when mixed with water to form dispersed colloid-size particles. There are two common types of Bentonite for commercial use; sodium (or swelling) Bentonite and calcium Bentonite.

Bentonite toxicology

Bentonite is non-toxic and inert. LKAB Minerals do not offer Bentonite for consumption in any form.
