Nitrogen Fixers
Convert atmospheric nitrogen into plant-available forms to support crop growth and improve nitrogen efficiency.
Activ8
Reduce Fertilizer Waste
Active8™ opens the biological pathways in your soil by stimulating the microbial activity that fixes nitrogen and other key nutrients into plant-available forms.
Fixes atmospheric nitrogen into plant-available forms.
Stimulates microbial activity in the soil that drives nutrient cycling.
Improves the availability and movement of essential nutrients in the root zone.
What it Does
Primary Function
Activates Soil Biology and Opens Nutrient Pathways
- Biological nitrogen conversion
- Rhizosphere colonization
- Enzyme-driven nutrient transformation
- Nutrient availability pathways
Pathways Opened
- Nitrogen conversion
- Nutrient cycling
- Root zone activity
- Mineral release pathways
Field Impact
- Captures atmospheric nitrogen and improves nitrogen efficiency
- Helps open blocked nutrient pathways identified through SFA analysis
- Enhances nutrient availability and biological activity in the rhizosphere
- Improves nutrient flow and crop performance
When to Use Activ8™
You want your inputs and nutrients to grow your crop, not stay locked in the soil or become lost through volatilization or leeching.
When your plant-available nutrient levels are low compared to total nutrient levels, you need help to open up the biological pathways that allow your crop to access key nutrients.
Activ8 is designed for fields where you want to improve nitrogen availability and stimulate biological activity in the root zone. By strengthening the microbial community, Activ8 helps open nutrient pathways and improve access to key elements like nitrogen, carbon, phosphorus, potassium, and calcium.

Primary Biology Groups
Nutrient Cycling Biology
Help break down and recycle nutrients already present in the soil, making them easier for crops to access.
Root Colonizers
Establish beneficial biology around the root system to support nutrient uptake and early plant development.
Multi-Nutrient Mobilizers
Help unlock and move key nutrients through the soil so they can flow more efficiently to the plants.

Customer Reviews
BTI products are easy to use. They’re tank mix compatible, so our customers aren’t making separate passes to use the products. This has made BTI easy to incorporate into their businesses.
Nathan M.

BTI has really changed the way we think about the crop in general—whether that’s below-ground soil fertility, soil health, or above-ground plant health.
Zach M.

We couldn’t keep competing the same way. We needed a whole new hand of cards. When you think microbial, that resets the whole paradigm for you.
