Humic acid is a natural, organic compound that provides plants and soil with a concentrated dose of essential nutrients, vitamins, and trace elements. Derived from Leonardite, a natural, organic compound formed over 70 million years, humic acids are among the most concentrated sources of plant nutrition. Unlike peat, which comes from a few thousand years of decomposed organic matter, Leonardite is the end product of nature's composting process, rich in vital elements for healthy soil and plants.

Humic acid granuies
By: Michelle on 2 April 2023
As an independent agronomist I was given some Humic acid granules to try. I applied them to an area where I sowed new seed for lawn. I didn’t have enough to do all of it but thought great I may see a difference. A year layer and preparing the preparing the area for seed again I could see the difference. The soil was darker, better structure and had better water moisture holding ability. Highly recommend this product for establishment whist the liquid Quantum H is great for ongoing improvement.
Humic acid is a MUST
By: Zac on 15 March 2023
Humate is a great way to get humic acid into the soil at an affordable price, application is a breeze and results speak for themselves, cant recommend this enough.
By far the best thing I’ve done this season
By: Andrew on 11 February 2022
I’ve long used liquid humic acid for my turf, but incorporating this granular formation has made a huge difference to this season. Seems to “magnify” the effects of other products.
Chelating agent
By: Colin-John on 11 January 2022
In the last year I have had success with liquid Quantum H so thought I would put down a longer term slow release granular humate. I am hoping at maximum label rates the detoxifying and chelating effect will reduce dog urine burns on the lawn which is the only thing holding my turf back now.
Extra soil supplement
By: Anferny on 11 June 2021
Having used the Quantum H product as the humic acid in liquid form which acts very fast but for short period of time.
Then decided to try in a granular form of the product and cant be more happier and can see result after few application as the lawn still staying lush and green compare to last winter was getting lots of purple blade due to sudden dropped in temperature.
Another product would recommend people to try on their lawn or even garden plant.
Great value

Great product and cost effective
Love this stuff
By: Aaron on 21 June 2020
Used this product when seeding a couch lawn in summer. After previously seeding without it, the results were significant. Germination was great, and the lawn was quick to fill in and is still going strong into winter.
Great for healthy roots
By: Kris on 24 August 2019
Used when seeding ryegrass. Created a really strong root system in no time at all.
HuMATE!!
By: robert on 2 August 2019
Added to my lawn and around plants. Soil is much richer after using 3 months ago with lots of worm activity. Very easy to use.
Black Gold!!

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!
