Specifications

Technical Information
NPK: 8-1-4 + micronutrients
Contains
  • Fish hydrolysate, providing amino acids and natural growth enhancers
  • Seaweed (Ascophyllum nodosum), rich in cytokinins, auxins, and anti-stress compounds
  • Humic and fulvic acids (USA-sourced), for increased nutrient chelation, improved soil CEC, and microbial stimulation
  • A blend of trace elements that address common deficiencies in Australian soils

How it Works

The Science Behind Activ8mate:

Activ8mate is a combined nutrient input and biological soil amendment designed to improve nutrient use efficiency (NUE), soil structure, and rhizosphere activity. It stimulates microbial processes responsible for nutrient cycling and mineralisation, enhancing root–microbe interactions within the rhizosphere. This results in improved nutrient availability through microbial conversion and chelation, while also supporting nutrient retention via better soil structure and cation exchange interactions.

In addition, Activ8mate contributes to improved soil aggregation, aeration, and water-holding capacity, while assisting in buffering salts and maintaining balanced root zone conditions. The overall effect is stronger root development, more consistent plant growth, and improved resilience to environmental stresses. Suitable for use in fertigation, foliar, and soil-based programs, Activ8mate integrates well with conventional fertiliser inputs, with performance influenced by soil type and growing conditions.

Application

Type Application Rate  
Minimum dilution rate: 1:100 Apply fortnightly or when feeding is required

 

General application:

1ml per 1 sqm

100ml/100m2

10L/ha

Lawns and Gardens: 

100ml/100m2

10L/ha

*Can be increased to 120ml/100sqm for boosted feeds.

Watering Can:

10-30ml/9L

*Apply to natives, orchids, African violets, and ferns at half-rate.

Hose‐on Bottle or sprayer:

Mix the minimum amount of water with the product/s to allow you to cover the required area/s.

*For example, on 10x10m space, add 100ml of each Seaweed Secrets, Activ8mate, and Nature's Soil Wetter, then top up with enough water to allow you to evenly cover it using the hose‐on bottle , then evenly hose‐on.

Hortex/Pressure/Knapsack Sprayer: You need about 10 litres of water to be applied per 100sqm, so take that into consideration when applying. If you have a smaller sprayer, either do several smaller applications (i.e., covering 50sqm using 50ml of product at a time and repeat until the entire area is covered). If using a Hortex sprayer on setting 2 without the restrictor, you shouldn’t need to add water, but if you do, just add as little amount to cover the required area.

 

  • For more information, please check out Resources tab on the top menu or refer to the rear label for application rates.
  • During warmer months, for best results, apply less but more often (i.e., weekly or fortnightly).
  • Apply all year-round to continue improving soil and feeding microbes.
  • During cooler months, apply less often or at a lower strength.
  • Shake well before use.

Great Product and service!

Loved watching our plants and lawn grow since using Activ8mate. The economy is great compared to other products on the market, and has extra other benefits. Awesome!

Far better fertiliser than anything from the Big G

By: Peter on 14 January 2019
Over the last few years, I have tried a number of different fertilisers for my Buffalo lawn and surrounding gardens, from Scotts, Yates, Seasol, and Neutrog. Compared to these, Active8Mate has made a drastic improvement to the appearance of the lawn. My Buffalo is far more hardy, healthy and lush, and my hedges are growing a lot faster and fuller (I can finally box hedge!). Although I invested in a backpack sprayer to get the best of the liquid fertiliser, it was a worthwhile investment especially considering how cost effective and economical Active8Mate is compared to other liquid fertilisers (e.g. Gogo Juice). All up, Active8Mate is Highly Recommended.

Excellent results and value.

By: Joshua on 17 January 2019
I’ve been using Activ8mate for the past 8 weeks and have noticed a considerable improvement in the growth and health of my lawn. Combined with Natures Soil Wetter and Seaweed secrets, it’s a winning combo at very affordable rates.

Fantastic results for growth, health & remedial wo

By: Jake on 31 January 2019
Incredible value for money per use. Turf is going ballistic growth wise, thickening up nicely and maintaining a deeper green. Used this product with PD soil wetter & PD seaweed to bring back a large part of turf that was poisoned 3 weeks ago. Today, everything is back to normal, growing at the same rate and just as healthy as everywhere else!

Great Value

By: Dane on 7 February 2019
Noticed improved growth after the first week and a half of use. Excellent bang for your buck, definitely will be using again.

Balanced liquid fert

By: jason on 12 February 2019
Got this with some stimuliser. Added together and sprayed the other week and can see that it’s helped soil health and maintained good leaf growth and health, nice even colour and growth. Great stuff!! Also have to mention I love the smell, reminds me of healthy organic material haha!

Elixir of plant life

By: Leo on 19 February 2019
Loved the 1 Litre bottles. But now ive discovered the 5 Litres. Ill be bathing in this as my lawns have dramatically improved, as ive demonstrated for years that i had a shocking lawn. After the first few apps you could see that Activ8mate was the cpr and now i can cut my lawn with confidence.

By: Saran on 7 March 2019
I’m very much happy with the product. My lawn was almost dead as it started to show black patches. Few applications of Acti8mate has done a great job, it’s green and pushy now after 6 weeks since first spraying. I recommend the product highly.

Perfect soil perfect lawn! I still can’t believe how complete this product is, it makes it almost too easy to take care of my lawn!

Thriving

By: Shayne on 11 April 2019
Using this in between granular ferts has given my lawn that extra boost it needed, over the growing season

Super Boost!!!

By: robert on 16 April 2019
Activ8mate has really taken my LaPrima Couch to the next level. Great growth even in Autumn.

Great for a boost

By: Rebecca on 25 April 2019
Great product for use on a regular basis in between granular fertiliser. Keeps the lawn ticking along nicely.

Wonder juice

By: Sean on 30 April 2019
Great product, had just finished up with a run of a rival product and switched to this after running with a bundle pack. Results seen within days. Incredibly fast results but didn't result in a surge in leaf but more a uniformed dense growth across the lawn. Post grubs and mites and this combined with a bundle pack has seen what was nearly a dead lawn , thick lush and most importantly healthy. A must buy

Great for in between granular runs

By: Jacob on 18 May 2019
I’ve been swapping between a granular fertiliser and Activ8mate and the results have been outstanding! Being a liquid fertiliser, it is easy to get great even coverage and has a lower risk of burning the leaf as it doesn’t sit or clump on it. Highly recommend on it’s own or as compliment to your existing lawn care.

Great product

By: Shannon on 3 June 2019
Been using it for a few weeks now. Seems like it’s working great. Can’t wait to use it in the growing season

Great product

By: Teena on 4 June 2019

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!
