Features

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

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.

Review of Liquid Fulvic Acid Lawn & Garden Biostimulant, Premium Soil Nutrient Chelator - 1L

Seed Germination

I have tried the fulvic acid on seed germination with fantastic results. Soaked Adenium seeds overnight in diluted fulvic acid.. the results were amazing, once the seeds were planted they germinated a lot quicker than normal with nearly 100 % germination. Very happy with this product and can totally recommend to others.

Review of MSM Capsules – High-Purity Organic Sulphur 460mg

MSM Supplement 460mg

This MSM Supplement has made a significant difference to my recovery from a serious Lis Franc foot injury after months of little to no improvement. Less pain and more elasticity in the badly injured area of the foot. Could not be happier.

Review of Quantum H® Liquid Humic Acid Lawn & Garden Soil Conditioner - 1L

Brilliant

I have been using Quantum H on my Santa Anna lawn now for years in conjunction with other PD products and the results have been consistently brilliant.

Review of PREMIUM Fossil Shell Flour®: Food Grade DE Diatomaceous Earth - Organic - 800g

Organic Diatomaceous Earth Powder (Food Grade Foss

I’m really impressed with Plant Doctor's PREMIUM Fossil Shell Flour. The powder is finely milled, so smooth it mixes easily into water, smoothies or morning coffee without any grittiness. It’s simple to use, and appreciate that it has no taste or smell. The 800g bag is great value and will last a long time when using a teaspoon daily. Have observed improvements in my digestion and energy levels, and general skin feel too. Delivery was super quick, and the packaging is resealable and well-labeled. The quality is outstanding, and I know exactly where I’ll be getting my next supply, definitely sticking with Plant Doctor. Many thanks to the team!
