The Science Behind Acitv8mate

Activ8mate is a high-performance liquid fertiliser and microbial soil conditioner, delivering both short- and long-term benefits.

Nutrient Profile: 

  • NPK: 8-1-4 + micronutrients
  • Fish hydrolysate, providing amino acids and natural growth enhancers
  • Blood & bone, for a balanced release of nitrogen and phosphorus
  • 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

Mode of Action:

  • Encourages microbial conversion of nutrients to plant-available forms
  • Enhances nutrient retention and soil aggregation, reducing leaching
  • Buffers salt levels and improves root zone aeration
  • Stimulates rhizosphere activity, enhancing root growth and long-term resilience

Application Notes:

  • Compatible with most foliar sprayers and fertigation setups
  • Ideal post-mow, during establishment, or integrated into IPM programs
  • Safe for environmentally sensitive zones (SGA-assessed)
  • Naturally variable—slight variation in analysis may occur due to mineral base

Applications

Method Details

Watering Can

10‐30ml per 9 litres of water.

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, for my front yard, using an old weed n feed hose‐on bottle I 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 (I add about 600ml water), then evenly hose‐on.

Hortex/Pressure/Knapsack Sprayer

You need about 15 litres (a little more or less won’t hurt) 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 at a time and repeat until the entire area is covered), or over a larger area spray with the required amount and if you haven’t used 15 litres/100sqm, give a light water‐in. 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 download Application Rates Document or please refer to the rear label for application rates.

I am using it with Bens special mix and alternate with Iron. Ordered my product and had them delivered within 48 hours (for free!!) Very helpful team and support to finding the right solution for my needs. Great experience as well as value for money and can’t wait to see the results of the products.

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!
