Our Products

Two Formulations,
One Natural Source

Both products are derived from our patented CaCO₃ extraction process — delivering highly bioavailable calcium carbonate with trace minerals essential for crop performance.

Foliar Application

Calcium Foliar Spray

Post-emergence · Cell wall & fruit development

A suspension of finely milled, natural calcium carbonate formulated for foliar application. Rapidly absorbed through stomata to address calcium deficiencies during critical growth stages — flowering, fruit set, and final sizing.

  • Prevents blossom end rot (BER) in tomatoes, peppers & cucurbits
  • Strengthens cell wall structure and membrane function
  • Extends post-harvest shelf life and fruit firmness
  • Improves nitrogen use efficiency
  • Resistance to heat stress and disease pressure
Produced via our patented process — non-toxic, does not burn roots or foliage.

Seed Treatment

Seed Inoculant

Pre-planting · Germination & root establishment

A natural calcium carbonate coating applied to seed prior to planting. As the inoculant breaks down in the soil, it enriches the rhizosphere with calcium and nitrogen — fuelling vigorous germination and deep root development from day one.

  • Improves germination rates and seedling uniformity
  • Stimulates vigorous root growth and nodulation
  • Naturally corrects low-pH soil at the root zone
  • Promotes early phosphorus & potassium uptake
  • Safe for transplanting — no root burn
Breaks down naturally in soil — no chemical residue, suitable for organic farming programmes.

The Science

How Calcium Carbonate
Transforms Your Crop

Calcium is a structural and signalling nutrient. Unlike mobile nutrients, it cannot be relocated within the plant — continuous uptake is required throughout the growing season.

1
Soil pH Restoration
Calcium carbonate counters the negative effect of aluminium on root growth in acidic soils, re-adjusting pH to the 6.0–7.0 range where nutrient availability is optimal. On saline soils, calcium displaces sodium to restore productivity.
2
Photosynthesis Activation
The nitrogen component within our CaCO₃ formula is a building block of chlorophyll and regulates the transcription of chloroplast proteins. Plants receiving adequate calcium-nitrogen show measurably higher photosynthetic rates and grain yield.
3
Cell Wall Architecture
Calcium is a primary component of the pectin network in plant cell walls. Strong cell walls mean better resistance to fungal penetration, reduced susceptibility to blossom end rot, and firmer, longer-lasting fruit.
4
Water Use Efficiency
Research shows 25–100% more plant-available water in calcium-treated soils vs untreated controls. This is especially significant in drought-prone regions and during high evapotranspiration periods.
5
Nutrient Uptake Synergy
Calcium increases ammonium, potassium, and phosphorus absorption efficiency — making fertiliser inputs more productive and reducing leaching losses. The result is lower total input cost per tonne of marketable yield.
Performance Data
"A calcium-deficient plant cannot compensate — the nutrient must be present at the right time, in a bioavailable form."

Agronomic Benefits

Measurable Field
Outcomes

Each benefit is underpinned by calcium's fundamental role in plant physiology — from the molecular to the marketable.

Soil pH Correction
Restores pH to the 6.0–7.0 optimal window, unlocking locked nutrients and improving microbial activity in the root zone.
Enhanced Photosynthesis
Nitrogen in the CaCO₃ formula supports chlorophyll synthesis and drives higher rates of photosynthesis across the canopy.
Vigorous Root Development
Promotes deeper, more branched root systems with better nodulation — improving anchorage and nutrient foraging volume.
BER Prevention
Prevents calcium-deficiency disorders: blossom end rot in tomatoes & peppers, tip burn in cabbage, cavity spot in carrots.
Water Use Efficiency
25–100% more available soil water in treated fields — critical during drought stress and in water-scarce production zones.
Disease Resistance
Stronger cell walls reduce fungal penetration. Calcium helps prevent powdery mildew, black spot, and heat stress damage.
Advanced Fruit Set
Calcium and potassium synergy improves flowering, fruit development, storability, and marketable shelf life.
Improved Germination
Seed inoculant supplies calcium at the root zone from day one, improving emergence rates and seedling uniformity.
Non-Burning Formula
Unlike many calcium chloride products, our CaCO₃ formula does not burn roots or foliage — safe at label rates in all conditions.
