Full-Spectrum Mineral Nutrition

STONE-AGE is formulated to provide a much broader mineral profile than a conventional calcium, magnesium or PK supplement.

Its mineral matrix supplies important elements including:

• Calcium
• Magnesium
• Potassium
• Phosphorus
• Silica
• Sulphur
• Iron
• Trace minerals

Providing a diverse mineral profile helps support the many structural, metabolic and enzymatic processes plants require throughout their life cycle.

Rather than focusing on only one or two nutrients, STONE-AGE is designed as a complete soil remineralisation amendment.

Geological & Volcanic Mineral Sources

STONE-AGE incorporates a diverse range of naturally occurring mineral materials selected for their complementary properties.

These include materials such as:

• Wollastonite
• Montmorillonite
• Leonardite
• Basalt
• Azomite-type mineral deposits
• Natural shell-based lime
• Sulphur-bearing materials
• Volcanic mineral sources

Using multiple geological sources provides a wider mineral spectrum while creating different nutrient release characteristics within the soil.

Calcium & Magnesium Support

Calcium and magnesium are critical secondary nutrients required throughout plant development.

STONE-AGE provides multiple natural mineral sources of these elements.

Calcium Supports

• Cell-wall development
• Strong plant structure
• Healthy new growth
• Root development
• Enzyme activity
• Nutrient transport

Magnesium Supports

• Chlorophyll production
• Photosynthesis
• Enzyme activation
• Plant metabolism
• Efficient energy production

The balanced mineral profile makes STONE-AGE useful for replenishing calcium and magnesium within depleted or repeatedly used growing media.

Silica for Structural Strength

STONE-AGE contains naturally derived silica-rich mineral sources.

Silica is widely valued in horticulture for supporting:

• Strong stems and branches
• Cell-wall integrity
• Plant structure
• Environmental resilience
• Resistance to physical stress
• Overall crop durability

Silica can be particularly valuable during periods of rapid vegetative development and heavy flowering when plants are supporting greater biomass.

Phosphorus & Potassium

STONE-AGE also provides natural sources of phosphorus and potassium.

Phosphorus Supports

• Root development
• Plant energy transfer
• Photosynthesis
• Flower development
• Plant metabolism

Potassium Supports

• Water regulation
• Nutrient movement
• Enzyme activity
• Structural development
• Flowering performance

These minerals are released as part of the wider soil biological and mineral cycle rather than acting like an aggressive soluble PK booster.

Sulphur, Iron & Trace Minerals

A healthy soil system requires more than NPK, calcium and magnesium.

STONE-AGE contributes sulphur, iron and a broad suite of trace minerals that support enzyme systems, chlorophyll production and wider plant metabolism.

Trace minerals may only be required in small quantities, but deficiencies can still negatively affect plant performance.

STONE-AGE helps restore mineral diversity to soils that have been repeatedly cropped or poorly remineralised.

Humic & Fulvic Compounds

STONE-AGE incorporates raw Australian humic and fulvic compounds.

These natural organic materials help minerals interact more effectively with the soil environment.

They can contribute to:

• Nutrient availability
• Mineral retention
• Cation exchange
• Microbial activity
• Soil structure
• Moisture retention
• Root-zone nutrient transport

This makes STONE-AGE particularly well suited to biologically active soils.

Helps Improve Cation Exchange Capacity

Cation Exchange Capacity, or CEC, describes a soil's ability to hold positively charged nutrient ions and make them available within the root zone.

STONE-AGE's combination of mineral clays, humic compounds and geological materials helps support the nutrient-holding characteristics of soil.

Improved CEC can contribute to better retention of nutrients such as:

• Calcium
• Magnesium
• Potassium
• Ammonium
• Important trace elements

This is particularly valuable when rebuilding depleted soil for repeated crop cycles.

Soil Remineralisation

Each crop removes mineral nutrition from the growing medium.

If that soil is reused without replenishment, mineral reserves can gradually become depleted.

STONE-AGE is specifically designed to help recharge and remineralise used soil, making it highly useful for:

• Recycled potting mixes
• Living-soil beds
• No-till containers
• Raised beds
• Re-amended GRO-DIRT
• Long-term organic systems

By replacing removed minerals, growers can maintain soil productivity across repeated cycles.

Soil Building Application

STONE-AGE can be incorporated when constructing new organic or living-soil mixes.

Use up to approximately 3.5% of total soil volume, depending on the overall recipe.

For example:

For complete soil building, thoroughly mix the amendment through moist growing media.

Allowing the soil to rest before planting gives biological processes time to begin interacting with the amendments.

Soil Recharging Application

For previously used growing media, apply up to approximately 2.5% of the total soil volume, depending on nutrient depletion and the wider amendment program.

Example:

Thoroughly incorporate the minerals through the growing medium and allow the re-amended soil time to biologically stabilise before intensive planting where practical.

Top Dressing

STONE-AGE can also be applied directly to established containers as a dry top dressing.

Apply evenly around the root zone or drip line rather than placing a concentrated pile directly against the main stem.

Lightly work into the upper soil surface where appropriate, cover with mulch if used, and water thoroughly.

Planting Hole Application

STONE-AGE can be incorporated directly into planting-hole backfill soil.

Use up to approximately 2% of the backfill volume.

For larger established transplants, a generous handful incorporated evenly into the surrounding soil can provide additional mineral support during establishment.

Avoid allowing concentrated amendment to sit directly against delicate bare roots.

Compost Tea Application

STONE-AGE can also be incorporated into aerated compost teas.

Use approximately:

0.5–1 teaspoon per 20L of compost tea

Aerate for approximately 24 hours under appropriate oxygenated brewing conditions and apply promptly after brewing.

The mineral addition provides additional surfaces and nutrients for interaction within the biological tea.

STONE-AGE + HERB-SUPERB

STONE-AGE is particularly complementary to High Powered Organics HERB-SUPERB.

The two products perform different roles.

STONE-AGE

Provides:

• Minerals

Ideal for GRO-DIRT

STONE-AGE contains many of the same types of mineral inputs used within the High Powered Organics GRO-DIRT range.

It is therefore particularly useful when recharging GRO-DIRT between crop cycles or providing additional mineral support during long-term cultivation.

STONE-AGE can replenish mineral reserves without replacing the biological framework already established within the soil.

Suitable for No-Till Growing

STONE-AGE is well suited to no-till and reusable living-soil systems.

Because the amendment consists of slow-release geological and organic mineral components, it contributes to long-term soil fertility rather than simply delivering a short burst of soluble nutrients.

In no-till systems it can be:

• Top dressed
• Incorporated during soil reset
• Used with organic amendments
• Applied beneath mulch
• Added during bed re-amendment
• Included in compost teas

Suitable Applications

STONE-AGE is ideal for:

• Living soil
• Organic soil
• GRO-DIRT
• Recycled potting mixes
• No-till beds
• Raised beds
• Fabric pots
• Outdoor gardens
• Greenhouses
• Indoor cultivation
• New soil construction
• Soil re-amendment
• Top dressing
