Stalled Growth Starts Underground
Bound minerals, weak root systems, chemical hardpans, compact soils and nutrient deficiencies hold back crop performance. Conventional fertilizers alone can’t always provide the nutrients your plants need—or help roots grow stronger and dig deeper.
The Microbial Advantage
Nutri-Cycle combines multiple biofertilizer strains to build a resilient, nutrient-rich growing environment from the ground up. Many of the organisms in Nutri-Cycle individually have been demonstrated in peer-reviewed journals to increase both the yield and size of plants, including stalks, leaves and root systems. However, when they are applied together as a community, that is where the real microbiological harmony begins.
Bigger root systems gives plants better access to nutrients and water resulting in better yields — proven in both research and field trials.
- What it targets
- Bound nutrients, weak roots and soil compaction.
- Where it fits
- Corn, soybeans and other crops where nutrient access limits growth.
- How it applies
- Seed treatment, in-furrow and soil applications.
Here’s the biology behind the benefits:
Discuss your application- Dissolves P, K, N and trace nutrients for better nutrient uptake in the soil
- Coats roots with beneficial microbes that deliver nutrients when needed and support deeper root growth
- Forms complex biofilms that help improve photosynthesis, plant vigor and resilience under stress
- Solubilizes phosphorus at a broad range of pH from 4.5 to 9.0. Most commercial products only solubilize phosphorus at a pH higher than 7.
- Breaks down plant residue and organic matter over the growing season, creating a slow-release fertilizer
- Improves soil structure by reducing compaction and increasing water retention
- Enhances organic matter year over year for a compounding yield effect
- Nutri-Cycle demonstrates the additive effect of combining multiple biofertilizer strains, creating a resilient, nutrient-rich growing environment that strengthens plants from the ground up.

How is Nutri-Cycle applied?
Nutri-Cycle comes in 40-acre mylar pouches (55 grams of microbes) for easy in-field use. Bulk 50 lb drums are also available for seed treatment professionals.
Which crops benefit most from Nutri-Cycle?
Nutri-Cycle is formulated for use on all row crops.
How long does it take to see results?
Farmers document improvements in crop yield and root depth from the first season, with enhanced yield compounding year over year.
Can it be combined with fertilizers or other treatments?
Yes. Nutri-Cycle is designed to complement your fertility program by improving nutrient availability and accessing previous year inputs that are paid for and are already in your soil.
Is it safe to use Nutri-Cycle with chlorinated water?
It is most likely harmful to use rural water sources that have chlorine in them with Nutri-Cycle. Well water is the preferred carrier. Rural water can be used with a suitable de-chlorinating agent in accordance with product specifications.
