BioBoost NPK – Reef Safe nitrogen and phosphorus solution

Reef Safe plant growth promoting blend:

  • Reef Safe – suitable for use near waterways, including the sensitive Reef Zone; may help to reduce run off by supporting lower fertiliser rates
  • Rebuild soil biota & reinvigorate soil health for better plant growth
  • Improve nutrient uptake for healthier, stronger plants
  • Supports improved resilience of plants to a variety of stressors

May reduce the need for applied Nitrogen-N and Phosphate-P fertilisers by up to two thirds.

Suitable for inclusion in IPM projects.

BioBoost NPK

A stabilised, post-fermentation, pre-mixed formulation incorporating

  • AspeN
  • RhizoPhos and
  • Squadron

with each working as per the descriptions below:


Azospirillum can convert atmospheric nitrogen into ammonium under microaerobic conditions at low nitrogen levels, through the action of the nitrogenase complex. Azospirillum brasilense also to its capacity to synthesize phytohormones, in particular indole-3-acetic acid.

The attachment of Azospirillum cells to plant roots occurs in two steps. The polar flagellum, of which the flagellin was shown to be a glycoprotein, mediates the adsorption step. Then a surface polysaccharide in the subsequent anchoring phase.

They display a versatile C- and N-metabolism, which makes them well adapted to establish in the competitive environment of the rhizosphere. They are used for leguminous as well as non-leguminous crops in symbiosis with soil rhizobial bacteria.

Nitrogen is required in the greatest amount of all nutrients transported to plants through the soil or leaf. It drives chlorophyll production in the foliage and is one of the key elements that help keep plants green and growing efficiently.

Azospirillum brasilense is a naturally occurring bacteria that are free living in the soil. tolerance of abiotic and biotic stresses promoted by inoculation of Azospirillum in plants, encompassing detoxification of oxidative stress, ISR and IST.


Bacillus amyloliquefaciens pre-emptively colonises the cytoplasmic membrane (root hairs) resulting in the subsequent formation of a protective biofilm making the plants more resilient to threats in the environment.

RhizoPhos contains gram positive endospores which are phosphate solubilising – supporting better uptake of applied Phosphate-P fertilisers as well as unlocking naturally occurring phosphorus in your soil. Its unique acceleration of the ATP – ADP function means Phosphate ions are gathered electrochemically by the bacteria and pulled into the plant, making the most applied and stored nutrients.

RhizoPhos also acts as an immunostimulant that works through the promotion of a naturally occurring salicylic acid response in plants. It is a broad spectrum root inoculant that also enhances germination and plant growth by competitively excluding diseases caused by a range of fungi and bacteria.


Squadron is a strain of Pseudomonas fluorescens, a plant growth promoting bacteria.  These bacteria live in the rhizosphere and utilise seed and root exudates to colonise and multiply.  They produce plant growth promoting substances to help enhance plant development. 

They also competitively exclude pathogens in the rhizosphere. 

Squadron helps the plant handle environmental stresses and may be used to induce frost protection through competitive exclusion.    

Works well with

  • RhizoGaurd
  • DiaSil
  • Mycorrhiza (VAM) – for improved nutrient uptake and enhanced drought tolerance

Safe for use with composts and other microbial inoculants such as Rhizobium and Trichoderma

Can be used in conjunction with

  • Nitrogen – N fertilisers
  • Phosphate – P fertilisers

Compatible with many commonly used fertilisers, pesticides and adjuvants.

AspeN contains 2 nitrogen fixating bacteria –

  • Azotobacter chroococcum
  • Azospirillum brasilense

RhizoPhos contains

  • Bacillus amyloliquefaciens (strain rm303)

Squadron contains

  • Pseudomonas flourescens

Nitrogen and Phosphorus

Assists with nitrogen fixation and phosphorus solubilisation.

Converts atmospheric nitrogen to plant-available nitrogen in the soil. The lower the available nitrogen in the soil, the greater the volume of atmospheric nitrogen it will convert.

Solubilises phosphorus, enabling greater uptake of applied and naturally occurring phosphate by the plant.

Resilience Boosting

Helps restore soil biota after continuous cropping, land overuse or other events causing a build up in the soil’s population of “bad biology”.

Promotes a Salicylic Acid Response to induce natural resistance. Pre-emptive colonisation of the cytoplasmic membrane (root hairs) results in the subsequent formation of a protective biofilm.

Pre-emptively colonises the rhizosphere to competitively exclude pathogens. 

Increased Nutrient Uptake and Utilisation

Increased uptake and utilisation of essential nutrients, such as Nitrogen, Phosphorus and Silica, and adsorption by active transport via electrochemically charged ion conduction pores.
