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.

Planet Earth Agronomy Pyramid describing their decision-making ethos at the bottom of the pyramid:- Soil health- Up to plant health- Human healthAt the top of the pyramid: Financial health

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.

Kevin D.

- Distributor, Upper Mid-West

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.

Troy T.

- Retailer, High Plains

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.

Nelson M.

- Retailer, South Dakota

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.

Chris H.

- Grower, South Dakota

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.
