Mighty green, Mighty good.

Contamination of inland waterways with nutrient run-off is a global problem with dire consequences.

Like people, plants need nutrients, but too much of a good thing can be a problem.

Nutrients are essential for plant growth, but the overabundance of nutrients in water can have many harmful health and environmental effects. An overabundance of nutrients—primarily nitrogen and phosphorus—in water starts a process called eutrophication.

Algae feed on the nutrients, growing, spreading, and turning the water green. Algae blooms can produce offensive odours, block sunlight, and even release toxins in some cases.

Here's the problem:

Algae feed on the nutrients in the water.
The algae blooms, growing and spreading.
The water turns green and smells.
It blocks sunlight and can even release toxins.
Waterways affected by eutrophication are taken over by rapidly growing invasive plants which leads to reduced biodiversity and impacts some bird habitats.

Plants known as aquatic macrophytes can thrive under these conditions. Plants such as the Common Reed and Cumbungi dominate waterways affected by eutrophication. These plants restrict waterflow and grow rapidly, growing 3-5 metres during a season, and may spread up to 5 metres laterally through underground roots.

These plants are very efficient at using excess nutrients found in waterways, releasing allelopathic chemicals to suppress other vegetation. These dense monoculture stands reduce biodiversity and habitat for some birdlife.

Our solution:

Tasked with controlling an invasive aquatic plant, our company knew that there was a better way to utilise green waste than for it to end up in landfill.

Through theoretical and applied research, our company developed a microbial process to produce two beneficial products from waste – a liquid biostimulant and high carbon biopellets.

We named this PhragMighty™, from the botanical term for the common reed – Phragmites australis.

It is mighty green, and it is mighty good.

The benefit to you:

PhragMighty -

Aquatic vegetation is routinely cleared from Australian waterways – but the waste is dumped or sent to landfill.

PhragMighty -

Diverting this waste from landfill reduces methane emissions and produces a product that benefits you – the grower.

PhragMighty -

PhragMighty™ contains trace elements and beneficial microbes, has been observed to increase drought and disease resistance, and improve root and shoot growth.

PhragMighty -

Contribute to our waterway health, and the health of your garden.

Mighty green. Mighty good.

These benefits are all available, knowing that your use of PhragMighty™ is diverting tonnes of carbon rich green waste - from landfill methane emissions, to a product that is beneficial to the environment.

Liquid Biostimulant

PhragMighty™ will be available as a liquid biostimulant, containing trace elements, beneficial microbes, and carbon.

The biostimulant has been independently laboratory tested for both nutrient and contaminant levels and has been plant tested on tomatoes, citrus, ornamentals and turf grasses.

Plants treated with PhragMighty™ were found to be more drought-resistant, disease resistant and show increased root and shoot mass compared to controls.

High carbon biopellets

PhragMighty™ is now available as a high carbon biopellet, benefiting soil microbiology, improving soil structure, and aiding in nutrient and water buffering.

The benefits of adding PhragMighty™ biopellets to soil include; a reduction in soil surface temperature, a habitat for beneficial microbes, increased nutrient buffering, improved drainage and the addition of complex carbons to the soil.
