Microbial Power to Unlock Phosphorus & Maximize Plant Performance

Mammoth P® Active Microbials by Mammoth Ag is a cutting-edge microbial enhancer engineered to dramatically improve nutrient efficiency, plant health, and crop yields. Powered by a proprietary consortium of beneficial bacteria, Mammoth P increases the bioavailability of phosphorus and essential micronutrients throughout every stage of plant growth.

Unlike traditional phosphorus additives, Mammoth P works biologically—converting unavailable nutrients already present in your medium into plant-accessible forms. The result is stronger root development, healthier plants, and improved overall performance without excess nutrient buildup.

With a near-neutral pH and a clean-running liquid formulation, Mammoth P integrates effortlessly into soil, coco, hydroponic, and soilless systems. It’s compatible with virtually all nutrient programs and is trusted by both commercial cultivators and home growers worldwide.
