Canadian-based Lucent Bio has introduced Soileos Boron + Zinc, a new granular fertilizer designed to improve boron nutrient use efficiency by reducing losses from leaching and aligning nutrient availability with crop demand.

Soileos Boron + Zinc is a granular, water insoluble, slow-release and seed safe boron fertilizer, built on Lucent Bio’s patented cellulose delivery matrix. Soileos uses microbial mineralization to release boron and zinc steadily throughout the growing season.

Managing boron is challenging due to the nutrient’s narrow application margin, high solubility and inconsistent uptake. Highly soluble boron sources leach easily from the soil, especially in sandy or high-rainfall regions, often requiring foliar sprays, in reaction to deficiencies that have already reduced yield. Lucent Bio says that Soileos Boron + Zinc enables “a proactive approach: applied at seeding, it supplies boron gradually over time, directly in the root zone, improving ROI.”

“Boron has always been difficult to use,” said Michael Riedijk, CEO of Lucent Bio. “Soileos Boron + Zinc gives growers a smarter, safer way to manage it. One that improves nutrient efficiency, simplifies planning, and delivers consistent results across diverse soil types.”

The product is designed to replace and reduce reliance on in-season foliar sprays by offering a soil-applied solution that can be broadcast, banded or placed in-furrow at seeding. Field evaluations show strong consistency across varied soil types, including sandy and high-pH soils, where boron management has historically been unreliable.

“We developed Soileos Boron + Zinc to solve the boron delivery problem, not just reformulate it,” said Farah Nour, chief science officer at Lucent Bio. “Microbial release allows us to synchronize nutrient availability with crop demand, improving nutrient efficiency, crop performance and soil health.”

Soileos Boron + Zinc builds on Lucent Bio’s existing portfolio of climate-smart fertilizers. A recent third-party lifecycle analysis found that Soileos products can sequester up to 2.3 tonnes of CO₂e per acre, making it one of the few crop inputs to offer both agronomic performance and measurable carbon benefits.

Lucent maintains that Soileos Boron + Zinc is a “breakthrough for low-carbon canola. As the first soil-applied boron product designed to reduce emissions and nutrient loss, it unlocks a critical piece of the puzzle for carbon-positive oilseed production.”

Soileos Boron + Zinc is now available for pre-order in the U.S.
