Founded in Innovation
As many of you know, we are entering an exciting new chapter at Midwestern BioAg. We’re returning to our roots – refocusing the business around what sets us apart: our unique, science-backed solutions that improve soil health, nutrient use efficiency, and farm profitability.
When Gary Zimmer and our other founders started this company, their mission was clear: deliver products and insights that couldn’t be found anywhere else. This mission remains at the core of everything we do.
Over the years, many of our fertilizers we helped pioneer became widely available. While we’re proud to have sparked that change, our next chapter is about focus – on our differentiated offerings, our proven products, and our commitment to partnering with those who believe in what we do. That means shifting our retail operations back to trusted channel partners and doubling down on what we do best.
Our Mission:
To empower growers and channel partners with solutions to enhance soil health, nutrient use efficiency, and farm profitability.
Our Vision:
Transform the food system by demonstrating that soil health-driven farming is the most profitable, sustainable, and responsible approach to feeding the world.
The ag industry talks a lot about ROI – and rightly so. Yield is critical. But yield alone doesn’t tell the full story. Agronomy is like a team sport. You can apply more nitrogen, but if potassium levels are low, that nitrogen might not deliver. That’s why context is key – and it’s what we specialize in.
One of the things I’ve come to appreciate most is this: we don’t just fix soil problems; we fix the problems others ignore. Because they can’t solve them, they assume they can’t be solved. As our Director of Research put it well: most growers are forced to “farm around the problem.”
Take Bio-Cal® as an example. Traditional agronomy says you can’t balance soil calcium-to-magnesium ratios – it’s not feasible. But we’ve been doing just that, with clear, repeatable results over the past three years. Our recent partnership with EarthOptics and their Tru-Till™ technology has further validated Bio-Cal’s role as the leading non-tillage solution to compaction. Even better, we can now show where it works best and measure ROI – on your fields.
We are staying grounded in practical innovations that being measurable, long-term results while delivering value in one year. And we’re doing it by working closely with partners like you – those who believe in improving farming from the soil up. We’re grateful for your trust and partnership. Thank you for being part of this mission. The best is yet to come.
