Your Trusted Agronomy Partner
Providing products, technology, and tools to the people who grow the crops that feed the world.
How We Work
Our "Farmer First" Approach
We exist to solve agronomic problems from the ground up, ensuring every recommendation is backed by hard data and proven in the field.
1
Rigorous, High-Quality Research
We don't guess; we test. Our foundation is built on using randomized, replicated test blocks across diverse soils and climates to generate the most robust and repeatable research data possible.
2
Independent Validation
We prove our performance in the real world. Beyond our own rigorous internal vetting, our products are continually validated through third-party and university trials.
3
Best-in-Class Evaluation Technology
We measure success from the roots to the canopy. We evaluate product performance using advanced technology, including drones, satellite imagery, and RNA and DNA soil and plant testing.
We pair these modern diagnostics with traditional agronomic measurements such as biomass, weight, height, and density to get a complete picture of crop health.
4
Enhancing Tradition
We know what it takes to farm profitably, and we don’t abandon the agronomic tools that have worked for generations — we improve them every season. By bridging advanced biology with traditional chemistry, we make your standard inputs work harder and more efficiently.
Our Approach to Choosing Products For your farm
THE PLANET EARTH AGRONOMY PYRAMID
Our Agronomy Pyramid explains how we keep our decision-making tied to our ethos of helping farmers and growers retain or grow profit whilst providing better care for their soil and crops. Typically, when we are brought onto a farm, it’s because something isn’t working — yields are low, disease is present, or crops are underperforming. This is how we build solutions from the ground up.
FINANCIAL HEALTH
ROI drives adoption. Farmers will only adopt technologies that improve their bottom line. Every product or technology we bring to market must demonstrate clear economic value on the farm.
HUMAN HEALTH
Healthier crops produce better food for people and animals. We focus on enhancing the nutrient density of the harvest and improving the safety of the application process for the farmer.
PLANT HEALTH
Improving soil health leads directly to stronger, healthier plants. We identify limiting factors and push the crop through critical stress periods to improve yield and performance.
SOIL HEALTH
We begin with soil health and nutrient availability, because in over 90% of cases, the root issue behind underperforming crops is soil imbalance or poor soil health.

I like their practicality really at the end of the day, they value the implementation and they understand that it's an ROI game...[the Planet Earth Team] are a tremendous wealth of information... their information is the key, you know, and they have the experience and everything needed to guide you in a direction that's going to be synergy.

I would highly recommend Planet Earth to anybody that has questions about the biological world, the biostimulants, something that they want to add to their portfolio and be able to offer customers and be comfortable with proven products and a lot of knowledge.

We take their advice. Yes. There's a lot of good and there's a lot of bad microbiology in the industry and with the research they have here at Planet Earth Agronomy, we've never been steered in the wrong direction.

We met Larry and the guys at Planet Earth Agronomy and everything's been great. They've been awesome to us and we just hit things off right away.
[They are] more about the passion than thier bottom line.

A lot of companies, they can get a product and take it to the market and have a big year with it and they disappear off the map. They got their money, they're gone onto the next thing... and that's just not the approach with [Planet Earth Agronomy]. And so their beliefs and who they are to the core is what makes me want to work with them.
