Plant Doctor Quantum-H helps improve, build & repair soil structure. It helps detox the soil from any heavy metals/pesticides/herbicides etc and is a great microbe food.
Quantum-H is a premium humic acid solution extracted from Agri-Plus, a high-grade leonardite ore. It has a high concentration of short-chain humic acid and fulvic acid molecules, and in addition is a very plant active liquid humic acid extract. It is manufactured using proprietary methods of extraction, settling, and handling, offering a lower sludge content and is easier to handle than other humic acid products - making it the industry benchmark.
DETOXIFIES VARIOUS POLLUTANTS
STRONGER HEALTHIER PLANTS
FEED BENEFICIAL MICROBES
Humics are the most natural and organic way to provide plants and soil with a concentrated dose of essential nutrients, vitamins and trace elements. They are complex molecules that exist naturally in soils, peats, oceans and fresh waters. The best and most concentrated sources of humic acids are derived from a compressed organic compound known as Leonardite derived from fresh water deposits. Leonardite is the completely decomposed remnants of living organisms derived from 70 million years of humification. Like manures and other organic compounds are used to build richly fertile compost, so too Leonardite is the end result of nature’s own composting derived at a time when the earth had minimal pollutants. As a comparison, Peat is derived from only a few thousand years of decomposed organic matter. Plant Dr Humic will help you grow plants like never before.

Can be mixed with almost all liquid fertilisers and liquid nutrients, including seeding, pre-planting, side dress and water runs.
SEED SOAK SOLUTIONS
Many research papers validate the benefit of applying humic acids to seeds or seed pieces. Soaking seeds with Quantum-H may lead to increased yields for potatoes, tomatoes, cabbages, rice, eggplants, cucumbers, and other field crops as well as greenhouse crops. Add 2 litres of Quantum-H per 76 litres of seed-soak solution.
REDUCING THE SALT INDEX
An added benefit of applying Quantum-H with liquid fertilizer is an ability to buffer the salinity and toxicity of fertilizers. Most phosphate fertilizers are formulated with ammonia, and seedlings are sensitive to ammonia toxicity as well as salt burn from applied fertilizers. By adsorbing ammonium and sodium cations, Quantum-H can reduce the toxicity of these fertilizers.
An excellent way to ensure improved emergence and early growth is by applying phosphate fertilizers with Quantum-H as a pop-up starter fertilizer. Add 1460ml. per hectare of Quantum-H to pop-up fertilizer solutions.
The most widely accepted use for liquid humic acid products is in pre-plant and starter bands. Quantum-H can greatly improve phosphate availability and stimulate the respiration rate of seedlings, which leads to quicker germination, faster root and shoot growth, and higher chlorophyll density. Apply 1460ml. or more per hectare of Quantum-H with all banded liquid nutrient solutions. Quantum-H also may improve the uptake of phosphates from banded fertilizers in two ways. First, humic acids sequester (chelate) soluble calcium and protect the phosphates from the calcium-phosphate interaction. Second, the amine functional groups on humic acids can absorb the phosphate anions, improving its availability for plant uptake.
Many researchers correlate plant growth with varying concentrations of humic and fulvic acids in the soil-water solution. For most crops, the greatest plant response to humic and fulvic acids runs anywhere from 10 to 100ppm. Adding Quantum-H to in-season water-run liquid fertilizers will provide ample humic and fulvic acids to stimulate plant growth. Quantum-H will also complex all plant nutrients and keep them plant available. In addition, it will reduce nitrate leaching and act as a nitrogen regulator to limit the "luxury consumption" of nitrogen. Quantum-H should be mixed with all banded, soil-applied and water-run liquid fertilizers. Application rates of 2 to 4 litres of Quantum-H per 38 litres of fertilizer will assure the proper concentration of humic and fulvic acids will be reached.
The use of small quantities of humic acid has demonstrated an incredible ability to flocculate the soil, increase water penetration, and reduce water run-off. Adding Quantum-H to your water-run liquid fertilizer will enhance water penetration. Additional applications of 1460ml. of Quantum-H per hectare several times during the growing season will reduce puddling, sealing, and run off. In addition to Quantum-H, a seasonal application of Agri-Plus® - a 70% granular leonardite blend – will provide you with an abundant supply of humic acids to improve soil structure throughout the growing season.
GENERAL DIRECTIONS FOR USE
3-6 litres per hectare in enough water to provide thorough coverage or 1000 litres of water, reapplying 2-6 times during the growing season
Apply 6-10 litres of Quantum-H per Hectare. (preferably apply over multiple applications). It may be water run, side dressed, mixed with soil applied liquid nutrients or sprayed directly on the soil.
ADDED WITH NUTRIENTS:
Apply 2-4 litres of Quantum-H per Hectare mixed with the liquid nutrients. Add Quantum-H to a partially filled tank. Include Quantum-H with every application.
SPRINKLER OR DRIP IRRIGATION:
Smaller amounts of Quantum-H may be applied in every irrigation instead of only one application. Quantum-H is not corrosive to pipes or nozzles and will not plug them.

I have been using Quantum H on my lawn since my lawn reno. I cannot recommend this product enough - it has definitely helped improve the root system of my buffalo.
Very happy with the results
By: Chris on 12 November 2020
I received this as part of the Ben Sims mix and wasn't exactly sure on what it did. But when I used the mix as described the soil health improved immensely. I have very poor drainage and horrible soil and this, along with the rest of the Ben Sims mix has turned it around. Lush soil full of the right microbes and a near perfect PH. Very happy indeed!

By: Geoff on 3 September 2020
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. Soil quality has dramatically improved and the plants have never looked better. I recently had to dig up some irrigation for repair when I noticed how rich the soil looked, it even smelled rich. A game changer.

Easy application, full confidence
By: Tracey Pate on 15 May 2020
This is the perfect solution for me to use with a sprayer. I was undecided about whether to granules or liquid, but am so pleased I went with this one. It's great that it comes in a range of sizes. Now that I've tried the 1L and know that it works for my application (vegetable beds - 100sqm) I can go up to the next size next time.

Easier than mixing powder!
By: Jacob on 18 May 2019
I was using a powder humic acid in the past with a paint mixer attached to my drill. This worked but required a bit of extra work. Thought I'd give this liquid a chance and I'm glad I did.

Great for lawn health
By: Matthew on 23 March 2019
This stuff is awesome, really noticed the difference to lawn health since I started applying it. Highly recommended! Delivery was lightening quick..
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.
By: Ashley on 13 November 2018
Been using on both garden and lawn with great results. Both lawn and garden have never looked so healthy. I highly recommend this product, you won't be disappointed.
By: Mathew on 4 November 2018

First time owning lawn. Gave the team at plant doctor a ring and they supplied me with a wealth of information. Products turned up quickly.
Will definitely be getting more 8 weeks difference been using stimulizer, activ8mate, soil wetter, seaweed secrets and champion fertiliser. Was super fast delivery.
Amazing products!! The results are excellent and the prices are even better! Postage was only 2 days as well. Highly recommended!
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!
