Oath® Soil Life regenerates soil by replenishing the soil microbiome.

Compacted and degraded soil disrupts nature's carbon and nutrient cycles, causing trees to struggle and lose their resiliency.

Oath Soil Life is a probiotic + nutrient system that puts back the missing microbial life to reengage these beneficial cycles and restore soil structure.

How it works

The beneficial microbes in the Oath Soil Life system play a crucial role in metabolizing complex carbon compounds in the soil, originating from various sources, including the plants. A significant portion of this carbon derives from atmospheric carbon dioxide, which plants transform into sugar and transport via their roots into the soil, making it accessible to the soil microbes. The soil microbes transform the carbon and other compounds into metabolites that support the vitality of the plants.

The key to the consortium is its diversity. With a community teeming with life, the microbes fill missing niches and customize themselves to the specific needs of each situation. Without this diversity, wide swathes of unfilled niches would be missed.



A healthy soil microbial community helps to release nutrients trapped in the soil, making them accessible to plants.

Oath Soil Life has been tested in over 200 trials across a broad range of tree and plant types with thousands of repeat customers.
      We saw a huge boost in nutrient density. Our gardens have never looked healthier or more lush.
