Better soil. Bigger rebellion. Welcome to the Soil Revolution. At UUSI TERRA, we’re bringing an anti-fertilizer attitude to an industry overdue for a shake-up. Our Planting Protocol and Structure blends are your way in. But we’re selling more than products. We’re building a movement to make soil science make sense, get more hands dirty, and give everyone the know-how to leave this planet better than we found it.
MEET YOUR UNDERGROUND COMMUNITY
FIVE POWERHOUSE PRODUCTS.
EACH
WITH A JOB TO DO.
THE PLANTING PROTOCOL:
THREE IS BETTER THAN ONE. Three products. One powerful protocol. Where each plays a distinct role. Together, they maximize your soil’s potential. So much more than just another fertilizer product on the shelf—this is a soil-first movement putting nature first.
THE STRUCTURE BLENDS
THE PROTOCOL IS JUST THE BEGINNING. Meet Structure Garden Blend and Structure Turf Blend—targeted soil support for flourishing gardens and thriving lawns. More ways to grow from the ground up.
— THE LIVING PROOF
OUR WORK WORKS
Add UUSI TERRA and watch as the soil does its work quietly and the landscape gets the applause.
Explore before-and-after projects, hear from the people doing the planting, and see what a soil-first approach looks like in practice.

MEET
THE LIFE BEHIND THE REVOLUTION
Fungi. Protozoa. Nematodes. Bacteria. The underground forces that make better dirt possible—and the reason our science starts with soil.
FUNGI
Nature’s underground network. Fungi help build soil structure, while beneficial mycorrhizal fungi extend roots’ reach for water and nutrients.
PROTOZOA
Small grazers. Big recyclers. These single-celled organisms feed on bacteria, releasing nitrogen and other nutrients in forms plants can use.
NEMATODES
Microscopic worms with a major role. Beneficial nematodes recycle nutrients by feeding on microbes, while others help regulate pests within the soil food web.
BACTERIA
Tiny but mighty. These single-celled microbes break down organic matter, cycle nutrients, and help bind soil particles into structure that supports roots.
Benefits of Eco-landscaping
— IN THEIR WORDS
From backyards to bus shelters
The experience behind UUSI TERRA spans residential landscapes, municipal work, and a Boston bus-shelter green-roof . Different settings. A shared focus on the ground supporting them.
