Liquid Fertilisers


1 Litre — Order Code: GDF003

10 Litre — Order Code: GDF022

20 Litre — Order Code: GDF023

An amino acid based biostimulant or “vitamin pill” for plants and the soil.

Aminogro is produced through a proprietary industrial digestion process of crustacean shells and other marine wastes from the Australian seafood industry. The final liquefied “broth” is fortified with trace minerals and Vitamin C to produce a naturally complex plant and soil food containing free amino acids, polypeptides and proteins.

Nutrients are rapidly absorbed into plants in the presence of Aminogro. This significantly improves fertiliser efficiency and plant response times, particularly when the plant is under physiological or environmental stresses.

  • Improves Brix, Specific Gravity and Baumé levels in plants and fruit
  • Improves fruit and flower colour, uniformity and size
  • Improves post harvest storage life of vegetables and fruit
  • Improves the stress tolerance levels of plants
  • Assists the plants natural pest and diseases resistance
  • Enhances the uptake and assimilation of trace mineral to rapidly correct minor micronutrient deficiencies
  • Improves soil structure, water holding capacity and CEC levels
  • Supplies organic nitrogen (glutamic acid) to the plant and soil

Vegetable Crops and Tomatoes:

10ml/L every 10–14 days.

Berry Crops:

10ml/L every 10–14 days during cropping phase.

Wine Grape Vines:

5L/ha every 10–14 days from bud swell up to pea size berries stage. Further sprays may be required after veraison if hot weather (over 300°C average daily temperature) persist into grape maturity. Two post harvest sprays are also advised to improve carbohydrate reserves for next seasons crop.

Tree Crops (nuts, pome fruit, stone fruit, mangoes and exotic tree crops):

10ml/L every 20–30 days.

Nursery, Seedlings, Cut Flowers, Herbs, Bananas, Sugarcane:

5ml/L every 10–14 days. Seedlings should be sprayed approx. 5 days before emergence. After emergence apply twice weekly for 2 weeks then every 10–14 days. Treat sugarcane sets with a 20ml/L solution in the dip.


5ml/m² every month.

Citrus, Ferns, Orchids, Carnations and Other Known Sensitive Species:

4ml/L every 10–14 days.

Soil Applications

Application of Aminogro® should be applied or injected into the irrigation system towards the end of watering. It is necessary to apply enough water to carry Aminogro® into the top 20cm of the soil profile.

Annual Crops

Apply to soil before planting @ 40L/ha with Synertrol® Horti Oil @ 1L/ha. Good results are to be achieved also if Aminogro® is sprayed with pre-emergent or other non-selective herbicides prior to ground preparation. Aminogro® will assist in speeding up the breakdown of trash and weed residue.

Perennial Crops

Apply at 40L/ha just prior to budswell, fruit set, and vegetative flushing.

20 Litre — Order Code: GDF026

A natural plant growth promoter which includes fish protein, high analysis kelp, polysaccharides, natural chelating agents, humic acid, fulvic acid, liquid vermicast and a plant extract called triacontanol. Triacontanol has been found to provide a profound response in a variety of crops. University trials have produced crop yield increases ranging from 9–121 % using this remarkable substance. Black Gold can be used for both foliar and fertigation applications and helps to build brix levels, increase stress and frost resistance, chelates minerals and promotes soil life.


  • Excellent all-rounder for broad spectrum nutrition and plant growth promotion
  • Triacontanol is a photosynthesis-enhancer, which is the most important of plant functions
  • Can be used frequently as it is not overloaded with N.P.K.
  • Ideal as a rescue remedy following periods of stress ie transplants, heat frost or storm damage
  • A completely natural product
