Calcium Bentonite added to soil or water, disperses into tiny sub-micron particles.
These mix with sand other soil components. The calcium bentonites are reactive materials and when dispersed have a massive surface area which is also reactive.
This chemical reactivity of the calcium bentonites gives soil many of the properties we understand as being typical of good, productive soils.
Soil structure from binding of sand grains into aggregates has the capacity to hold water and the ability to hold and release nutrients. Additionally, it has the ability to support diverse and healthy bacterial populations and produce healthy vigorous plant growth.
