The Plant / Soil / Microbial Matrix is the foundation of all dynamic and sustainable eco-systems. A healthy soil is supported by a vast world of microbes: bacteria, viruses, and fungi that live in or on the plant system. Ignoring any of the key components will ultimately compromise any regeneration project. Microbes support plant health by increasing the availability of nutrients, enhancing plant root growth, neutralizing toxic compounds in the soil, making plants more resistant to disease, heat flooding, and drought. Microbes also deter pathogens and predators that could be harmful to plant establishment and longevity. 

Perfect for urban, suburban, and agricultural soils that have been abused, AM 120 Mycorrhizal Inoculum works together with a plants root system extending it throughout the surrounding soil area and significantly improving water and nutrient absorption while reducing the need and frequency of applying outside fertilizers. AM 120 helps plants establish strong healthy root systems quicker than non-inoculated seeds. By extending the reach and efficiency of the host plants root systems, mycorrhiza greatly enhance the plant's ability to survive and even flourish in dry conditions and in nutrient-poor soils including sites with a low pH or a different chemical composition.

Mycorrhizal fungi form associations with 90% of plants and can adapt to different biological, geological, and climatic conditions. In addition, it produces miles of hyphae throughout the soil to transport moisture and nutrients back to their host and supply them with their primary food source of carbohydrates. Both spores and hyphae are capable of colonizing a host plant once they have made contact with the plants roots. Therefore, fragments that contain spores or hyphae are considered propagules or inoculating agents. It is estimated that the amount of carbon filtered from the atmosphere is increased by over 40% or more.

AM 120 is the proven standard for Mycorrhizal Inoculants in Restoration.

Seeding Rates:

  • 60lbs. Per acre (67.5 kg/ha)
  • 1.4 lbs. Per 1,000 ft²(0.7 kg / 100 m²).

Rate provides approximately 3,600,000 living propagules per acre (8,956,000 propagules /ha).

Hand Seeding: Evenly distribute across seedbed after seeding. Cover the exposed seed and inoculum by raking in. Do not leave inoculum exposed to sunlight for more than four hours.

Hydroseeding: Apply in first pass with seed. A second pass with mulch to cover exposed seed and inoculum is recommended.

Seed Drilling: Incorporate into the soil at a depth ranger at or below the seed.

Broadcast and Till: Evenly distribute across seedbed after seeding. Cover the exposed seed and inoculum by harrowing, chain dragging or applying an organic topdressing. Do not leave inoculum exposed to sunlight for more than four hours.

Row Crop Applications: Side dress seed furrows or transplants at rates of 5 to 8 lbs. per acre (5.61 kg/ha) on 30 inch to 40 inch spaced rows. Rate provides 18 to 28 living propagules per linear foot of row crop (60 to 90 living propagules per meter of row crop). Incorporate at 2 inches to 6 inches (5 to 15 cm) below soil surface.

Nursery Medium: Evenly blend at 5 lbs per yd³ (3 kg. Per m³). 1 lb. (454 grams) contains approximately 60,000 living propagules. Rate provides 300,000 living propagules per yd³ (396,000 living propagules per m³) or 6.5 living propagules per in³.


Always wear a dust mask when handling.
