Release tied-up nutrients
Microbial activity helps make soil nutrients more available for crop uptake.
Biofertility microbial blend
Unlock nutrients that are already in your soil.
Nutri-Cycle brings a community of beneficial microbes to the root zone to help release tied-up nutrients, support deeper root growth, and build a more resilient growing environment season after season.
Application
Available in 40-acre mylar pouches for field use, with bulk drums for seed treatment professionals.
Nutrient access
Helps mobilize phosphorus, potassium, nitrogen, and trace nutrients so roots can use more of what is present.
Root support
Beneficial microbes coat roots, support deeper growth, and help crops reach water and nutrients more effectively.
pH range
Supports phosphorus solubilization across a broad pH range from 4.5 to 9.0.
Stalled growth starts underground
When soil ties up nutrients, fertilizer alone may not be enough.
Bound minerals, shallow root systems, compacted layers, chemical hardpans, and nutrient deficiencies can all limit crop performance. Nutri-Cycle is built to help biology work alongside your fertility program, especially where conventional inputs cannot fully solve the root-zone challenge.
Build deeper roots
Root-colonizing microbes help plants explore more soil for water and nutrition.
Improve soil function
Residue and organic matter cycling can support water retention and reduce compaction pressure.
The microbial advantage
Nutri-Cycle combines multiple biofertilizer strains instead of relying on a single organism. Individually, many of these organisms have been studied for their ability to support plant size, vigor, root development, and yield. Together, they create a broader microbial community around the roots.
The biology behind the benefits
- Helps dissolve phosphorus, potassium, nitrogen, and trace nutrients for better soil uptake.
- Coats roots with beneficial microbes that can deliver nutrients when the crop needs them.
- Forms biofilms that support photosynthesis, plant vigor, and resilience under stress.
- Breaks down plant residue and organic matter over the season, helping create slow-release fertility.
- Supports better soil structure by improving water retention and reducing compaction pressure.
- Contributes to organic matter gains that can compound over time.

Frequently asked questions
Frequently Asked Questions About Nutri-Cycle
How is Nutri-Cycle applied?
Nutri-Cycle comes in 40-acre mylar pouches with 55 grams of microbes for 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?
Growers may document improvements in yield and root depth in the first season, with soil and yield benefits designed to build over repeated seasons.
Can it be combined with fertilizers or other treatments?
Yes. Nutri-Cycle is intended to complement fertility programs by improving nutrient availability and helping crops access previous inputs already in the soil.
Is it safe to use Nutri-Cycle with chlorinated water?
Chlorinated rural water may harm the biology. Well water is preferred, and rural water should only be used with a suitable de-chlorinating agent according to product specifications.
