The Oath Microbial Discovery Engine

460 million years ago, plants developed roots in the soil and co-evolved functional relationships with the microbes surrounding their roots to enhance each other’s ability to survive storms, droughts, floods, fires, and freezes.

460 million years ago, plants developed roots in the soil and co-evolved functional relationships with the microbes surrounding their roots to enhance each other’s ability to survive storms, droughts, floods, fires, and freezes.

Recently, advanced genomic technologies enable us to sequence the DNA of the soil microbiome to uncover the specific roles these microbes play. Still, humans have characterized fewer than 1% of soil microbes.

This is our science at Oath:

Our microbiologists and data scientists sequence the DNA of the soil microbiome, characterizing these microbes to uncover their specific soil functions, such as:

Carbon Cycling
Nitrogen Fixation
Water Holding Capacity
Soil Structure

This is our science at Oath:

We compose diverse, targeted microbial communities to replenish the soil microbiome for all applications, rigorously testing each consortium in vitro and in planta.

Proven by performance

We have more than 20 years of data from over 220 pilot studies, demonstrating clear efficacy and replicable results.

Increased Yield by 160% & Provided an Additional Lift with Fertilizers

Average of 2 potato trials – Locations: Nyamagabe and Muzanze; Rwanda, Season A 2024/2025

Organic Fertilizer = animal dung and plant residue compost, NPK (1-0.2-1) 10 t/ha = NPK 100-20-100

Inorganic Fertilizer = NPK (17/17/17) 300kg/ha = NPK 51-51-51

Fully Fertilized = organic and inorganic fertilizer

Replenishing the soil microbiome.

Oath Soil Life is a fully characterized diverse microbial consortium backed by decades of research and demonstrated efficacy.

The Oath Microbial Discovery Engine

Soil microbes evolved 1 billion years ago. Without them, there would be no plants.
