In 2012 Silicon was categorized as a “beneficial substance” by the Association of American Plant Food Control Officials (AAPFCO).  Prior to AAPFCO approval, all silicon products were listed on fertilizer labels as a “non-plant food ingredient”.

With the new designation, manufacturers can now identify qualifying formulations of silicon as a “plant beneficial substance” – an important distinction.

Dr. Joseph Heckman published an article in 2013 for Better Crops with Plant Food that gives an excellent overview of the element silicon and why it is worthy of being a "plant beneficial substance".

Silicon Literature


See how researchers have found applications of MontanaGrow increases biomass and essential nutrient uptake in Wheat more than Wollastonite or lime.

From lab studies at LSU and MSU to USDA Hops field trials and a first-of-its-kind Montana organic dryland crop research center. MontanaGrow continues to expand organic crop research on new species.


The amorphous structure and cation exchange capacity (CEC) of MontanaGrow allows the soil to increase moisture storage and nutrient uptake, much like a sponge. Derived from a deposit known in French as a Nuee-Ardent  - glowing rock  or in Latin as an Ignimbrite  - Fire Cloud Rock.

Learn more about the science of Silicon and variety of research projects MontanaGrow is involved in below.



Silicon comes in many forms as it cycles through the earth.  The science of silicon in agriculture is relatively new in America.  Silicon is commonly overlooked as a significant contributor to plant science. 

Understanding MontanaGrow amorphous silicon on a geologic level requires specialized tools to see the porosity and non crystalline nature of the source rock.


For a better understanding of the diverse role silicon plays in promoting plant health and soil productivity, reading the following books are a must:


  • "Silicon in Agriculture" by L.E. Datnoff, G.H. Snyder and G.H. Korndorfer is the first book to focus on the importance of silicon for plant health and soil productivity and on our current understanding of this element as it relates to agriculture.
  • "Silicon Solutions - Helping Plants Help Themselves"  by Edward Bent takes a holistic look at silicon's influence on soil structure, soil microorganisms and in the context of plant stress.
