A boron-zinc carrier on a pyridoxine base, designed to feed crops more safely and help them withstand abiotic stress.
A Sanitrum patent application (2025/014197), advanced in collaboration with Olimpum as the commercial channel. Presented here in the light of established plant science; field application is still ahead.
Feeding crops under stress, without over-dosing
Boron is unforgiving
Boron has the narrowest safe range of any plant nutrient: the gap between deficiency and toxicity is very small, so conventional boron carries real over-dose risk.
Total ≠ available
Not all zinc in tissue is active. Zinc bound in synthetic chelates is pH-sensitive, so total zinc can read high while the available fraction runs low.
Drought, salinity, cold, heat
These are among the largest pre-harvest causes of yield loss, delaying germination and damaging flowering and fruit set.
Natural-origin, multi-directional
A dedicated, natural-origin carrier that addresses nutrition and stress together is a rare open gap in the market.
Established, peer-reviewed plant science
Two well-documented facts frame this work. First, boron is essential for pollination and fertilization, required for pollen germination and pollen-tube growth, and so for fruit set. Second, vitamin B6 (pyridoxine) is a proven plant antioxidant and abiotic-stress protectant. A third, documented signal ties them together: under drought, the fluid in a plant's xylem becomes more alkaline (a rise in pH), which changes how pH-sensitive chelates behave.

A carrier that stays available through pH shifts
On this foundation we designed a boron-zinc complex on a pyridoxine carrier. The hypothesis: keep boron and zinc bioavailable to the plant through the pH shifts of abiotic stress, with less of the energy cost a plant spends cleaving synthetic chelators, so nutrition and stress protection are delivered together. The molecule and its use, as plant nutrition, a biostimulant, and an anti-abiotic-stress agent, are covered by patent application 2025/014197.
Stated honestly: the established science above is settled and peer-reviewed. The carrier-delivery advantage over synthetic chelates is our design hypothesis, still under validation. There is no field application yet; the project is at the science and patent stage.
In the light of agriculture
The intended applications span crop nutrition and stress resilience, from cereals to fruit trees, where safe boron delivery and abiotic-stress tolerance matter most. Two routes to value are envisaged: a standalone product and a value-add component for existing fertilizers, alongside licensing, in step with Green-Deal and Farm-to-Fork directions. Commercialization is planned through Olimpum, a Bursa crop-nutrition manufacturer with 125+ products exporting to 60+ countries.
Grounded in science. Built for the field ahead.
A patented, natural-origin carrier concept for safer boron nutrition and abiotic-stress resilience, ready to move from the bench toward validation with the right partners.
