Highlights
Not every technology fits neatly into my TECHXponential™ model, but some innovations are too innovative to pass up on reporting.
- This is a progression from the soil microbiome conversation: MaxSil adds the mineral dimension to the relationship among microbes, roots, plants and fertilisers.
- MaxSil isn’t a microbial product: It’s a silicon-based soil amendment made from recycled lime-soda glass.
- Plant-available silicon could improve resilience: The potential benefits include stronger root systems, improved nutrient uptake and greater tolerance to salinity, drought, heat and disease.
- The commercial case extends beyond sustainability: Better nutrient availability could reduce exposure to fertiliser price volatility and supply disruption.
- The evidence is promising but incomplete: Company-reported trials require transparent, replicated, multi-location and multi-season validation.
Plant-available silicon is the focus of this follow-up to my article on The Soil Microbiome Economy. Not every technology fits neatly into my TECHXponential™ model, but some innovations are too innovative to pass up on reporting.
This isn’t a repeat of the microbiome argument. It’s the next step.
The previous article examined how biological inputs and microbial communities could reshape the farm input market. MaxSil introduces a different category of intervention. It isn’t a microbial product, a microbial inoculant or a soil microbiome treatment. It’s a mineral amendment that may influence the wider system in which microbes, minerals, roots, plants and conventional fertilisers interact. It's a distinction that matters.
From recycled glass to plant-available silicon
MaxSil says its patented Australian process converts recycled lime-soda glass into amorphous silica and plant-available silicon. Amorphous means the silica doesn’t have the rigid crystalline structure associated with some less soluble forms.
The company promotes powder and granular products for use across broadacre agriculture, horticulture, sugarcane, rice, cotton and pasture. It also highlights Australian manufacturing, NASAA certification and distribution through agricultural suppliers.
Its central proposition is straightforward. Waste glass becomes an agricultural input, and the resulting silicon is intended to become available to plant roots in a form plants can absorb.
Silicon isn’t generally classified as a primary macronutrient like nitrogen, phosphorus or potassium. However, plant-available silicon can influence root development, nutrient uptake, water relations and plant resilience.
The effect is highly context-dependent. It can vary according to crop, cultivar, soil chemistry, application rate and the presence of a particular stress. Silicon isn’t a universal replacement for fertiliser, and it shouldn’t be considered as such.
A review published in Frontiers in Plant Science describes how silicon may support plant responses to salinity and drought through improved water status, nutrient balance, root function and protection against oxidative stress.
The question is not whether silicon is magic. It isn’t.
The question is whether the right mineral input, applied to the right crop, in the right soil, under the right conditions, can help a farming system use existing resources more effectively.
What the reported trials suggest
MaxSil reports a 14 per cent barley yield improvement in saline Western Australian soils. It also reports a 47 per cent crop-yield increase in a Colombian rice trial.
Those results are commercially interesting, particularly because salinity is a major constraint on productive land and rice systems face increasing pressure from water, fertiliser and climate variability.
However, these should be understood as company-reported or reported trial outcomes. They aren’t independent industry-wide benchmarks.
That distinction is essential for Boards, agribusiness leaders and investors. A promising trial result can justify further investigation, but it doesn’t automatically establish a universal return on investment.
We still need transparent trial design, replicated controls, multi-location testing, multi-season results and complete farm economics. That means accounting for product cost, application, transport, labour, yield response, fertiliser changes and the value of improved resilience.
MaxSil’s public science resources provide useful information on its reported trials, plant uptake rationale and comparisons with other silicon sources. Its resources page also contains application documents, safety information and scientific reports.
Fertiliser resilience is a strategic issue
The Strait of Hormuz disruption has exposed how dependent global agriculture is on imported fertiliser, energy markets, shipping routes and geopolitical stability.
That disruption was a reminder that farm input security is also food security is also national security.
Reducing fertiliser requirements by improving nutrient availability or uptake won’t eliminate conventional fertiliser. Nitrogen, phosphorus and potassium will remain critical to global food production. But even a partial reduction in waste, over-application or emergency procurement could matter.
The benefit would appear in several places. Lower exposure to volatile prices. Less dependence on freight availability. More resilience during geopolitical shocks. Potentially stronger farm balance sheets.
This is why I believe the MaxSil proposition should be considered as a strategic input question, not only an environmental one.
The world is moving towards 11 billion entities, comprising 9.7 billion humans and 1.3 billion pet cats and dogs. Meeting that demand won’t be achieved by removing conventional agriculture. It will require systems that extract more value from every hectare, every unit of water and every kilogram of fertiliser.
Recycled glass + plant-available silicon + better nutrient use = greater agricultural resilience.
Biologicals and mineral amendments aren’t competitors
Biologicals work through organisms, microbial communities or biological control mechanisms. They may introduce beneficial organisms, support existing microbial activity or influence plant health through biological pathways.
MaxSil works differently. It supplies a mineral input that may alter nutrient availability and plant responses, particularly under stress.
These approaches could be complementary rather than competing systems.
A microbial community depends on its chemical and physical environment. Roots release compounds into the soil, microbes transform nutrients and minerals influence the availability of elements around the root zone. The soil is not a collection of isolated products. It’s a combined living and mineral network.
A biological input may help activate the system. A mineral addition may help make more resources accessible within it. Conventional fertiliser may still provide the nutrients required to maximise yield potential.
The future farm input program could therefore look less like a choice between biological and synthetic products, and more like a coordinated system built around soil conditions, crop genetics and measurable outcomes.
Where the wider technology stack fits
This is where agriculture connects with the broader technology landscape.
Alternative proteins and cellular agriculture will create new demand for reliable, efficient and traceable feedstocks. Their success will still depend on crops, sugars, oils, nutrients and energy. Every efficiency gain upstream will affect the economics downstream.
Genomics can identify crop varieties with stronger root systems, better silicon uptake or greater tolerance to salinity and drought.
Microbiome science can examine how mineral amendments influence root-associated organisms, nutrient cycling and plant-microbe communication.
Synthetic biology may eventually design biological systems that work alongside mineral additions, creating more targeted interactions between plant roots, microbes and available nutrients.
That’s the larger opportunity. Not a single product replacing an entire input category, but multiple technologies working together across the food system.
The leadership question
The leadership question is not whether every farm should immediately adopt MaxSil.
The better question is whether your organisation has a disciplined process for evaluating technologies that sit between established categories.
For agribusinesses, that means running properly designed local trials. For manufacturers, it means examining supply resilience and circular production. For food companies, it means understanding how upstream input innovation may influence cost, availability and sustainability claims.
I believe MaxSil is worth watching because it combines three powerful ideas. Waste recovery, mineral science and fertiliser resilience.
The evidence needs to keep developing. The opportunity deserves attention now.
