Science That Yields 

By harnessing the power of microbes, plant extracts and algae to rejuvenate the rhizosphere, our portfolio of proven biologicals transform the soil structure and optimize soil fertility and micronutrient uptake for consistent results and greater profitability.

Our technology platform has been refined across millions of acres to rapidly improve soil structure while offering alternatives and complements to traditional fertility and crop protection programs.

“I use SP-1 simply because I’ve seen fantastic results and it’s repeatable on different crops. Every single year I’ve used it, I’ve seen a good response and I’m improving the soil. Soil health and soil improvement makes a huge difference on crop productivity.”

Dr. Mike Orzolek Emeritus Plant Science, Penn State University and DPH Biologicals Agronomy Consultant

“GROWMARK started working with SP-1 a few years ago in the Northeast. The ability of this product to consistently improve soil’s physical characteristics has been phenomenal, resulting in increased profitability for our customers. We plan to expand use of this biofertilizer across all of our sales territories in the next growing season.”
