When to use SI-Pro™
Silicon plays a key role in strengthening plant structure and helping crops handle stress. When silicon is available, plants are better able to maintain growth, regulate nutrients, and stay productive under pressure.
If your SFA report or field conditions indicate compaction, poor soil structure, or increased stress risk, SI-Pro helps reinforce both the soil and your crops.
Growers often use SI-Pro in fields with drought risk, heavy soils, salinity concerns, or where maintaining crop strength and consistency is critical.

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.

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.

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.
