Activ8EXTRA is a premium, biologically boosted liquid fertiliser designed for professional growers, turf managers, nurseries, landscapers, and agricultural operations seeking reliable nitrogen performance with added soil health benefits. The formulation combines a high-analysis NPK base with organic inputs including fish hydrolysate, seaweed extract, humic substances, blood & bone, and fulvic acid, creating a balanced liquid nutrition source that supports both plant growth and soil microbial activity. With rapid nitrogen availability, improved nutrient mobility, and enhanced soil biological stimulation, Activ8EXTRA provides consistent results across turf, ornamentals, broadacre crops, horticulture, nurseries, vineyards, and large green spaces.

For best results, apply fortnightly during the warmer months. During cooler months, apply less often and/or at lower strength. Best applied all-year round to continue improving soil and feeding microbes.
Agitate well before use.
As there are many conditions that affect the exact amount needed and the frequency of application for each product, there is no one-size-fits-all solution.
| Application Method | Instructions |
|---|---|
| Watering Can | Mix the amount suggested (typically 10‐30ml) per 9 litres of water. Spread evenly across the area to fertilise. |
| Hose‐on Bottle (Seasol/weed ‘n feed etc.) or Hortex 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 or Activ8EXTRA, 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. |
| Pressure/Knapsack Sprayer | You need about 15 litres (a little more or less won’t hurt) of water to be applied per 100m², so take that into consideration when applying. If you have a smaller sprayer, either do several smaller applications (i.e., covering 50m² at a time and repeat until the entire area is covered), or over a larger area spray with the required amount. If you haven’t used 15 litres/100m², 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. |
Activ8EXTRA is a high-performance liquid fertiliser designed for professional turf, landscape, and horticultural programs. It delivers fast-acting nitrogen combined with seaweed, fish hydrolysate, humates, and blood and bone to support vigorous growth, root development, and soil microbial activity across large-scale operations.
Both products support soil biology and plant performance, but Activ8EXTRA provides a higher nitrogen load, making it ideal for commercial turf, sports fields, broadacre greenspace, and any site requiring strong, leafy growth. Activ8MATE offers a more balanced nutrient profile suited to soil conditioning, year-round plant health programs, or rehabilitation of depleted soils.
Application frequency varies depending on crop type, turf demands, soil conditions, and seasonal growth cycles. Most commercial programs use Activ8EXTRA as part of a regular feeding rotation during periods of active growth.
Rates depend on the turf or crop type, environmental conditions, and specific agronomic objectives. Always follow your program guidelines and conduct small-scale testing when adjusting volumes or blends.
Yes, Activ8EXTRA is used nationally on buffalo, couch, kikuyu, zoysia, and professional sports turf surfaces including stadium fields, golf course fairways, and turf farm production areas.
Yes, it is suitable for leafy crops, ornamentals, trees, shrubs, turf, and general landscape applications. For phosphorus-sensitive Australian natives, trial first to assess compatibility.
For turf, application after mowing allows optimal foliar contact and prevents removal of product with clippings. For commercial crops or landscapes, apply according to your standard operational timing.
Light irrigation or rainfall after application helps move nutrients into the soil profile and supports biological activation, especially on large commercial turf or horticultural sites.
Yes, Activ8EXTRA is compatible with most liquid fertilisers and biological inputs. Avoid mixing with iron-based products and always perform a jar test before large-scale tank mixing.
Yes, once the product has dried. Restrict access to treated areas until surfaces are fully dry to prevent unintended contact with active ingredients.
Activ8EXTRA contains nitrogen, phosphorus, potassium, essential trace elements, seaweed extract, fish hydrolysate, blood and bone, and high-quality humates including fulvic acid to support both plant and soil performance.
Yes, but apply during cooler parts of the day and ensure adequate irrigation to prevent stress. Many commercial operators use it strategically to maintain colour and growth during challenging conditions.

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.
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!
