Bentonite is of interest to gardeners due to its water holding ability.

Use at a minimum rate of 1 - 4kg per m2 on coarse sandy soils, the general rule being the poorer the soil, the more Bentonite to use, up to a volume of 3 - 5%. It needs to be worked into at least the top 10 - 20cms. (We always recommend incorporating organic matter in addition to water holding minerals, as part of a complete soil improvement process.)  Our product is Calcium Bentonite, sourced from WA.

*Note - we recommend 'Sand Remedy', which is a pre-mixed product ready to use on your garden in place of soil wetting agents. It has a range of other minerals added, as well as trace elements, beneficial microbes, and a food source for them. It is designed for maximum efficiency and performance, and is easier to use than bentonite on its own.
