Stabilized Monosilicic Acid

Silicon is an underappreciated nutrient that is critical to thriving and yielding plants. Dune's monosilicic acid (Si(OH)4) liquid formulation is instantly plant-available and easy to apply both as a foliar spray or as part of a typical fertigation strategy.

Often left out of traditional liquid biofertilizers, this highly available form of silicon means greater and more immediate benefits to plants, and the stable formula won't clog up irrigation systems which means fewer headaches for the grower.

^{GUARANTEED ANALYSIS}

Soluble Silicon (Si) from monosilicic acid............2.2%

*Note: Orthosilicic acid (OSA) is chemically synonymous with monosilicic acid (MSA)

How it works

1. Apply Dune as a foliar or root drench.

2. The monosilicic acid is immediately available for plant uptake via root or other plant tissues.

3. When plants have higher concentrations of silicon in their tissues, they are stronger, more upright, and more resistant to breakage. They are also more tolerant of biotic stressors like herbivores and pathogens, and more resistant to abiotic stressors like chemical pesticides and climate variation.

Frequently Asked Questions

What is Dune?

Dune is a monosilicic acid product designed to support plant strength, stress tolerance, and physiological resilience through plant-available silicon. Silicon has recently been classified as an essential nutrient, indicating that it is a critical component of optimal plant function.

Why does Impello sell Dune?

We sell Dune because silicon is a powerful tool for helping plants withstand environmental pressure, improve structural integrity, and better tolerate stress.

How does Dune work?

Dune supplies plant-available silicon, which can support tissue strength, water relations, antioxidant function, and resilience under heat, drought, salinity, and other stress conditions.

Why does Dune matter to growers?

Dune matters because crop performance often depends on whether plants can maintain function under stress. Silicon helps plants build strength before pressure becomes visible, and improvements in vasculature and tissue strength translate across seasonal pressures.

What makes Dune different from other silicon products?

Dune provides silicon in the form of monosilicic acid, which is the only bioavailable form of silicon to plants. Traditional silica products require a long breakdown process in the soil before plants can absorb them, whereas Dune delivers rapid absorption via the roots or foliage.

How do I use Dune?

Dune can be applied both as a foliar spray or mixed directly into your irrigation water for root uptake. Because monosilicic acid is highly concentrated, always add Dune to your water reservoir first and mix thoroughly before adding other nutrients to prevent polymerization.

Dune is compatible with most nutrients, inputs, and crop protection. Notable incompatibilities are Calcium-Magnesium, kelp, depending on concentration of Calcium-crosslinks in the alginate.

Note: if you have questions on the compatibility of Dune with your current nutrient program, please contact us at info@impellobio.com.

When should I use Dune?

Dune is most effective when used proactively as part of a standard nutrition program. Begin applications during the early vegetative stage and continue through active growth and development to build cell wall strength before environmental stressors occur.

Note: Application strategies change based on your specific crop, location, substrate, goals and challenges. Contact an Impello advisor at info@impellobio.com to develop a program right for your operation.

How much should I apply and how frequently?

The general rule of thumb for Dune is a maintenance rate of 0.5 mL per gallon of water, applied 1 to 2 times a week. For foliar applications, a rate of 1 to 2 mL per gallon applied weekly is a standard starting point.
