2024 ProGro BIO Rhizol National Trial: Large-Scale Testing and Proven Results
For the second consecutive year, ProGro BIO has completed a large-scale field trial of its Rhizol microbial soil inoculant, reinforcing the product’s effectiveness in improving crop health, yields, and soil resilience. The 2024 program followed the success of the 2023 trials, maintaining its position as one of the largest independently sponsored and third-party monitored agricultural product programs in recent history.
The 2024 in-field program covered:
- 26 states across multiple agricultural regions
- Over 370 independent test plots
- Thousands of acres of crops treated with Rhizol
- Third-party monitoring and verification of results
“The 2024 Rhizol In-Field Trial Program was a resounding success in all aspects. Our soil inoculant demonstrated superior performance across a wide range of crop targets. Results included impressive yield increases, improved soil health, and enhanced plant resilience against pathogens.” — Zach Lancaster, Director of Field Research, ProGro BIO
Field Trial Results: Yield & Soil Health Improvements
Rhizol’s natural microbial formulation delivered consistent and measurable benefits, as reported by third-party consultants:
- Higher crop yields, providing economic benefits for growers
- Improved soil health and microbial diversity, enhancing long-term farm productivity
- Greater pathogen resistance, reducing the need for chemical treatments
- Increased soil resilience, allowing better adaptation to variable growing conditions
The Rhizol product line, tested in multiple forms—including dry dissolvable, seed treatment, and microbially-infused agricultural planter talc—showed effectiveness across varied soil types, climates, and agricultural practices.
“The 2024 results validate Rhizol’s ability to enhance soil health while delivering measurable yield improvements. Our all-natural, OMRI-certified microbial inoculant provides an efficient and organic solution for modern agriculture.” — Barry Roberts, Chief Operating Officer, ProGro BIO
