Description
Rapid Soil Regeneration, Nutrient Unlocking, Carbon-Rich Input for Professional Growers
Quantum H is a premium liquid humic acid soil conditioner engineered for large-scale turf, horticulture, and agricultural operations requiring fast, measurable improvements in soil structure, nutrient efficiency, and biological performance. Sourced from high-grade Leonardite, its concentrated short-chain humic and fulvic acids deliver rapid nutrient release, improved moisture infiltration, and enhanced microbial activity, making it a high-value input for soil repair, fertility building, and regenerative farming programs. Ideal for commercial environments where soil performance directly impacts yield, turf quality, labour efficiency, and input ROI.
Use Quantum H when your soil shows signs of organic carbon deficiency, poor nutrient uptake, or symptoms of “nutrient lock-up.” It’s especially valuable for rehabilitating soils affected by chemical residues such as herbicides, pesticides, or heavy metals. In hydrophobic or compacted soils, it helps improve moisture infiltration and microbial activity. It’s also an essential input for growers transitioning to regenerative or organic farming systems, where building long-term soil health and fertility is key.
Why commercial growers choose Quantum H:
- Rebuilds depleted, compacted, or chemically stressed soils
- Increases water retention, porosity, and infiltration
- Enhances fertiliser efficiency (especially P, N, and trace elements)
- Binds and neutralises salts, herbicide residues, heavy metals, and contaminants
- Pushes nutrient availability through strong chelation and CEC enhancement
- Stimulates beneficial microbes and accelerates humus formation
- Boosts root development and plant resilience
- Clean, low-sludge formulation suitable for fertigation and large-scale spraying
- Compatible with most fertilisers and biological inputs (avoid iron-based products)
Nutrient Profile:
- Humic substances: liquid potassium humate concentrate
- Contains organic carbon complexes and naturally occurring trace minerals
- Designed to improve soil chemistry, nutrient availability, and biological efficiency
Quantum H's low sludge formulation makes it easy to handle and ideal for various application methods. Rich in bioavailable organic carbon, it supports soil biology and long-term fertility. Quantum H is compatible with most crop inputs including fertilisers, pesticides, fungicides, and biologicals, except iron-based products, which should be applied separately. It can be used year-round and is particularly effective when applied during seedling, transplanting, fertigation, or pre-planting to activate soils and boost early plant development.
If your soil is compacted, tired, chemically stressed or nutrient-poor, Quantum H is your reset button. With every drop, you’re restoring balance, feeding life back into the ground, and giving your plants the foundation they need to thrive. Use Quantum H when your soil shows signs of organic carbon deficiency, poor nutrient uptake, or symptoms of “nutrient lock-up.” It’s especially valuable for rehabilitating soils affected by chemical residues such as herbicides, pesticides, or heavy metals. In hydrophobic or compacted soils, it helps improve moisture infiltration and microbial activity. It’s also an essential input for growers transitioning to regenerative or organic farming systems, where building long-term soil health and fertility is key.

Features
Quantum-H functions as a soil performance and nutrient efficiency catalyst, not a nutrient source. Quantum H has the following benefits:
Chelation & Nutrient Release
Breaks bonds that lock nutrients in the soil, making them available to plants
Water Retention & Soil Structure
Improves porosity and reduces runoff, helping roots access more water
Microbial Activation
Feeds soil microbes that break down organic matter and cycle nutrients
Soil Detoxification
Binds and neutralises heavy metals, herbicide residues, and excess salts
Carbon Source
Supplies organic carbon critical for soil biology and humus formation
Root Support
Encourages deeper, more fibrous root growth for better drought resilience
In summary:
- Improves soil cation exchange capacity (CEC)
- Enhances nutrient retention in the root zone
- Chelates and unlocks tied-up minerals in soil
- Stimulates microbial population activity
- Improves soil structure, aggregation, and moisture dynamics
- Increases fertiliser efficiency across all inputs
How it Works
Quantum H is more than a soil conditioner; it's a soil activator that changes the way your soil functions at a biological and chemical level. Powered by short-chain humic and fulvic acids extracted from high-grade Leonardite ore, it enhances the soil’s cation exchange capacity (CEC), buffers pH, stimulates microbial life, and unlocks bound nutrients in the soil matrix. Humic substances are the most active component of organic matter in soil, formed through the natural breakdown of ancient plant and animal materials. Within this group are three key compounds:
- Humic acids – large, complex molecules that improve soil structure and nutrient retention
- Fulvic acids – smaller, water-soluble molecules that chelate nutrients and facilitate their rapid absorption by plant roots
- Humin – the least active, most stable fraction of organic matter
Quantum H contains a high concentration of short-chain humic and fulvic acids, which are more biologically active and effective than longer-chain forms. This makes it a fast-acting, high-performance input.
