Premium Liquid Humic Acid Soil Conditioner for Healthier, Fertile Soil
Quantum H isn’t just another soil additive—it’s a powerful organic soil conditioner made to repair tired, nutrient-starved, or contaminated soils and turn them into rich, living ecosystems that support healthy plant growth. Formulated from premium Leonardite ore, Quantum H delivers short-chain humic and fulvic acids that work fast to unlock nutrients, detoxify chemicals, and feed soil microbes—restoring balance and fertility from the ground up.
Why Choose Quantum H?
Rebuilds damaged or depleted soils
Boosts water retention & soil structure
Feeds beneficial microbes and unlocks nutrients
Binds harmful residues (salts, pesticides, herbicides, heavy metals)
Improves root development and nutrient uptake
Compatible with most fertilisers and crop inputs
Organic, clean, and easy to apply
Who It's For & How to Use It:
Lawns (Buffalo, Couch, Kikuyu & More)
Helps recover from poor soil, drought, or compacted turf
Boosts nutrient efficiency when combined with fertilisers
Improves root development and water penetration
Apply after scarifying, aeration, or topdressing
Use with seaweed or wetting agents for a complete soil program
Gardens (Veggies, Flowers, Trees, Pots)
Detoxifies urban garden beds from chemical residues
Recharges depleted potting mix and garden soil
Enhances water-holding capacity—especially important in raised beds and sandy soil
Mix with compost tea, fish hydrolysate, or seaweed for added biological benefits
Farms & Larger Properties
Ideal during pre-planting, side dressing, or fertigation runs
Helps buffer pH, reduce nutrient lock-up, and bind salinity
Improves performance of applied fertilisers (especially phosphorus and trace elements)
Stimulates beneficial microbe populations and humus formation
Useful in regenerative agriculture and carbon farming programs
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.
The Science Behind Quantum H
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.
Function
How It Helps
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
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.

I have been using Quantum H for about 12 months now and the difference is striking. Initially I was using it on my lawns with other Plant Doctor products but I now use it on the gardens also.

By: Jacob on 18 May 2019

A+
By: Emma on 13 December 2018
I have been using this product with Natures Soil Wetter. Have achieved great results!
Great product, highly concentrated
By: Tony on 30 November 2018
I chose to use the Quantum H as a complimentary measure to Seaweed Secrets. I understood the need for soil conditioning, but also the need to have plant nutrition available on demand and without leeching. Humic and Fulvic Acids help regulate soil ph, bind elements that are not desirable such as by products of synthetic applications/products and provide valuable carbon as well. As a novice, do research into the proven scientific and peer reviewed benefits of Humic and Fulvic Acid.
Well worth investing in.

Only have great things to say about Plant Doctor. Organic products and a competitive price, fast shipping and easy to contact with questions. Have had great results with the special mix for lawns, and my plants (indoor and outdoor) love the seaweed secrets. I am excited to test out some of the animal products soon!
