Mammoth® P – Unlock More Phosphorus. Grow Stronger Plants. Harvest Higher Yields.

Mammoth® P is a premium microbial inoculant that boosts phosphorus and micronutrient availability, helping plants thrive from seedling through bloom. Developed by leading Colorado State University scientists using a patented trait-selection platform, it features a specialized consortium of beneficial bacteria screened from millions of soil microbes. These microbes are more than 30× more effective at cycling phosphorus than typical agricultural or natural soil communities.

How It Works

Phosphorus often binds quickly in growing media—up to 70% can become unavailable—limiting root development, energy transfer, flowering, and overall yield. Mammoth P’s beneficial bacteria act as living micro-bioreactors. They continuously produce enzymes that convert bound phosphorus and micronutrients into plant-available forms, improving uptake efficiency without adding excess nutrients or raising EC/PPM.

Key active microbes include:

Pseudomonas putida
Comamonas testosteroni
Citrobacter freundii
Enterobacter cloacae

Key Benefits

Increased nutrient bioavailability — Unlocks phosphorus and micronutrients already present in your medium for better uptake.
Higher yields and quality — Supports denser flowers, stronger stems, shorter internodes, improved vigor, and documented yield gains (including peer-reviewed results showing significant boosts in plant performance).
Healthier root zone — Helps protect the rhizosphere by outcompeting potentially harmful microbes.
Clean-running formula — Near-neutral pH; won’t clog lines or leave residue.
Universal compatibility — Works seamlessly in soil, coco, hydroponics, and soilless systems. Use as a supplement to any fertility program (not a replacement).
Sustainable edge — Optimizes (and in some cases can help reduce) synthetic phosphorus inputs while maximizing returns.

Ideal Use

Mammoth P shines during high-demand periods (bloom/fruiting) but benefits plants from clone or seedling stage onward. Apply consistently for best results throughout the crop cycle.

Directions (typical):
Shake well before use. Mix approximately 0.6 mL per gallon of water and apply twice weekly. Follow specific rates for your medium and growth stage as needed. Best used within 6 months of opening for optimal microbial activity. Colour variation or sediment is normal and indicates high microbial activity.

Why Choose Mammoth® P?

Backed by university research and independent testing, Mammoth P delivers science-driven performance trusted by commercial and home growers alike. Pair it with your existing nutrient program to cultivate stronger, higher-yielding plants more efficiently and sustainably.
