Ash and silts provide the same array of nutrients and micro-nutrients for plants as the clays do, but without the binder properties of clay. This organic soil amendment just did not get the pressure-cooker treatment to convert this to clay.

Our ashen silt has been tested and tried. We have analytical lab reports similar to our bentonite reports showing the mineral, nutrient and micronutrient content.


Here is a Trace Mineral analysis for this resource:

Calcium and iron are essential for strong plants. Strong plants are more pest and disease resistant. Our ashen silt has good levels of bio-available calcium and iron.

The array of major, minor and trace minerals in our clay and ashen silt provides the necessary nutrients for all plants, throughout their growing cycle.


Still in Development.
