mg/L is equivalent to the report’s g/m³. <1 means below the reporting limit, not zero. These are total elemental results; nutrient forms, plant availability and biological activity were not established by this panel. Nitrogen, sodium, boron, cobalt, molybdenum, selenium and density were reported as tests not accredited.
Density: 1.2 g/mL. pH: not reported; testing remains pending.
Calcium, magnesium and the quantified micronutrients are present at trace concentrations. The sample results do not establish a guaranteed minimum for every batch or a micronutrient-deficiency correction rate.
Inside the formulation
NPKS nutrition plus the Carbon Boost base
- Water-soluble NPK inputs supply targeted nitrogen, phosphorus, potassium, and sulphur.
- Carbon Boost base carries charged biochar, fish hydrolysate, seaweed tonic, and molasses.
- Fish hydrolysate adds amino compounds and marine-derived nutrients for plant and soil biology.
- Biochar and seaweed support nutrient efficiency, root-zone function, and plant resilience.
Max NPKS is designed to address active plant demand while retaining the wider biological foundation of the Carbon Boost formulation.

Application approach
Eurofins sample analysisElemental nutrients (% w/v): N 9.1%, P 0.8%, K 2.3%, S 9.7%. Eurofins report AR-26-NU-112834-01, 16 October 2026. Submitted-sample results; natural batch variation applies. pH was not reported.
200 L drums and 1,000 L IBCsSupplied in a practical bulk format for commercial liquid-fertiliser application.
- Use during periods of active pasture or crop nutrient demand.
- Apply as part of a planned liquid nutrition programme.
- Match rate and frequency to crop type, growth stage, soil condition, testing, and the existing fertiliser programme.
- Use suitable application equipment and follow normal good fertiliser practice.
- Agitate thoroughly before use and maintain suitable agitation during application.
- Contact Biocharge to confirm water volume, compatibility, equipment suitability and MAX-specific grazing/harvest advice. Follow the current label and use appropriate PPE.
Important: The working analysis and programme guidance above are supplied by BioCharge. Final rate, frequency, timing, compatibility, and application method must be matched to soil and plant testing, crop or pasture demand, equipment, and qualified farm-specific advice.
