EarthMAX® Tech Specs

EarthMAX® is used in intensive plant management to help increase root development and stress conditioning.

EarthMAX® has a concentrated photosynthetic biological package containing, but not limited to:

  • Bacillus amyloliquefaciens: Naturally occurring bacteria that is a growth enhancer through the enzymes it produces.
  • Bacillus megaterium: Used as a soil additive in agriculture and horticulture. Produces a large variation of enzymes and recycles organic matter in soil. Plays a significant role in the carbon and nitrogen cycle and breaks down rock phosphate.
  • Bacillus subtilis: Also known as the grass Bacillus. Naturally found in soil. Reduces nitrate and supports plant growth. Forms biofilms in the root zones. Bacillus subtilis has been identified as inducing plant’s systemic response against disease.
  • •Bacillus licheniformis: Is a saprophytic bacteria that degrades thatch.

Other Bacillus present in EarthMAX® cycle nutrients and reduce ammonia, nitrites, and nitrates. This process produces cytokinins and a wide variety of enzymes that enhance the natural biological processes in the soil to expedite nutrient transfer to the root zone.

EarthMAX® also contains ecto-mycorrhizal fungal spores.

EarthMAX® contains humic and fulvic acid. Unlike all other Leonardite humates, the patented cold-water extraction process of EarthMAX® ensures that the biology present in the product survives in the production of EarthMAX® and is stable in a highly concentrated form.

EarthMAX® comes from one of the highest fixed carbon deposits on earth. The carbon in EarthMAX® helps the soil hold on to nutrients and moisture. Soil high in carbon stays moist longer after rains and irrigation, has better structure for the growth of roots and exchanges nutrients more efficiently than soil with less carbon.

EarthMAX®’s 16 essential nutrients help provide complete fertilization, complementing standard N, P, K and micronutrient programs.

Our ascophyllum nodosum, cold-processed Seaplant Extract contains elements known to be essential for turfgrass health and growth
