Stabilized Monosilicic Acid

Dune is a stabilized form of monosilcic acid which is the most bioavailable form of silicon. This highly concentrated liquid formulation is instantly plant-available and easy to apply both as a foliar spray or as part of a typical fertigation strategy.

Dune's unique formulation offers superior stability and compatibility, resulting in better plant performance and easier handling for growers. As a free-ride compatible product, Dune mixes easily with crop protection and nutrion sprays and won't clog emiters or fall out of solution.

^{GUARANTEED ANALYSIS}

Soluble Silicon (Si) from monosilicic acid............2.5%

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

How it works

1. Apply Dune as a foliar or root drench.

2. Immediately available to the plant, monosilicic acid forms in the plant cell wals rapidly to strengthen the crop, boosting plant vigor and greenness.

3. Higher concentrations of silicon in plant tissues will result in stronger, more upright plant growth that is resistant to breakage. The plant can better tolerate abiotic stressors like salinity, heavy metals, nutrient imbalance, UV radiation, drought, heat, and frost.

Technical Sheet Label Safety Data Sheet

Dune™ x Cherry

This trial was conducted to see if adding Dune™ to standard foliar calcium fertilizers would improve calcium uptake, leaf structure, and fruit quality in Brooks variety cherries. By testing the mixture in California orchards, the grower found that Dune rapidly boosted calcium levels in leaf tissue just three days after application. The report suggests that the silica strengthens the tree's vascular system, which enhances its photosynthetic capability and helps it transport nutrients much more efficiently.

Dune™ x Riesling Grape Production

A study evaluated the foliar application of Dune™ to Riesling grapevines and found that it significantly boosted yields without negatively affecting grape quality (Brix, pH, and TA). Dune™ also outperformed calcium and standard fertilizers, increasing cluster numbers and weight.

Dune™ x Asexual Propagation of Poinsettia

A trial evaluated Dune's impact on root development in two poinsettia cultivars. Dune enhanced both root vigor and formation speed, leading to faster plug fill and quicker transplanting. These improvements can benefit growers by reducing propagation time and enhancing overall efficiency and plant health.

Dune™ x Frost Damaged Citrus Trees

A grower treated frost-damaged citrus trees with Dune monosilicic acid, Lumina amino acid fertilizer, and calcium acetate to restore canopy health. Spectrometer data over 10 days showed increased calcium and boron translocation. Results suggest these treatments aided rapid nutrient mobilization, benefiting both damaged and healthy tissues.

Dune x Continuµm x Leafy Greens

A commercial grower compared Fosphite biopesticide to a biostimulant program (Dune monosilicic acid + Continuµm microbes) to assess yield impact. Nine leafy green varieties were tested across three treatments: Fosphite, biostimulant, and untreated control. Yield (oz/plant) and percent increase in yield (*PIY) were analyzed for each variety.

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.
