TSN: Maximize Nitrogen Efficiency & Protect Your Fertility Investment
Nitrogen is one of the most important drivers of crop yield — but also one of the most vulnerable. Every year, millions of dollars’ worth of nitrogen fertilizer is lost to volatilization, leaching, and denitrification before plants ever have a chance to use it. Unprotected nitrogen doesn’t just hurt your bottom line. It reduces efficiency, weakens plant health, contributes to greenhouse gas emissions, and erodes long-term soil fertility. That’s why Taurus, The Fertility Company, offers TSN: a field-ready stabilized nitrogen solution designed to protect every tonne you apply.
Keep the nitrogen you paid for.
Untreated urea can lose 20–50% of its nitrogen to volatilization, leaching, and denitrification before your crop ever uses it. TSN is field-ready 46-0-0 with a dual-action stabilizer built in — so more of every tonne stays in the ground, available, and working.
across all soils
1 Agronomics
Nitrogen you apply is worthless if it never reaches the crop.
After urea hits the soil it starts breaking down immediately. Unprotected, it gasses off as ammonia, leaches below the roots, or denitrifies into the air. TSN’s dual-action system protects it above and below ground.
Stops the gas-off at the surface
NBPT (N-(n-butyl) thiophosphoric triamide) inhibits the urease enzyme, slowing urea conversion and giving rain time to move nitrogen into the soil. More N stays put instead of venting as ammonia.
Holds N in the stable form longer
DMPP (3,4-dimethylpyrazole phosphate) slows nitrification, keeping nitrogen in the ammonium form. Less nitrate means less leaching on sandy soils and less denitrification on heavy ground.
On average, TSN delivers about 66 lbs/ha more nitrogen into the soil bank than untreated urea — and held twice as much nitrogen in stable urea form in a 21-day University of Manitoba incubation study.

Soil type doesn’t save you. Broadcast losses were nearly identical on sand and loam (131.9 vs 129.9 lbs/ha). The application method drives the loss — and TSN closes it on every soil.
2 Economics
Stop paying for nitrogen that gasses off the field.
At a ~$10/acre investment, TSN protects the most expensive input on most farms. Retained nitrogen shows up as retained yield — here is what the numbers say, and a calculator to run your own acres.
| Per acre | Investment | Yield saved | Revenue saved | Net profit |
|---|---|---|---|---|
| Wheat ($6/bu) | −$10.00 | 6.6 bu | +$39.00 | $29.00 |
| Canola ($13/bu) | −$10.00 | 5.7 bu | +$74.00 | $64.00 |
Your nitrogen, protected

3 Logistics
Field-ready out of the truck. No blending. No guesswork.
TSN is a finished 46-0-0 with both inhibitors built in — load it, spread it, seed it. You handle it like any urea; it works like a smart nitrogen system.
Dual inhibitor, factory-built
NBPT and DMPP are pre-treated on every prill. No in-shed impregnation, no on-the-go injection, no mixing errors at the spreader.
Broadcast, banded, or incorporated
Even protection holds across application methods and across cold or warm soils — urease and nitrification stay active well below the temperatures most growers expect.
Drops into your existing program
Compatible with standard seeding and fertilizer equipment. Same calibration, same storage, no extra passes.
Buys you a weather window
By slowing volatilization, TSN gives rain time to move nitrogen into the soil — widening the gap between application and the rainfall you can’t control.
The placement rule · every cm shallower costs money
| Placement depth | Risk | Potential N loss | Loss with TSN |
|---|---|---|---|
| 0 cm (surface) | Extreme | 50% | < 5% |
| 2.5 cm (1″) | High | 25% | < 3% |
| 5.0 cm (2″) | Moderate | 10% | < 1% |
| 7.5 cm (3″) | Safe zone | < 5% | 0% |
Every centimeter of shallower placement raises nitrogen loss by roughly 7–10%. TSN protects the application you can actually make — not the perfect one.
Protect your nitrogen. Protect your profits.

After urea is applied, it immediately begins breaking down in the soil. Without protection, nitrogen is lost through: Ammonia Volatilization (Gaseous nitrogen (NH₃) escapes into the atmosphere), Leaching (Nitrogen moves downward with water beyond the root zone), Denitrification (Nitrate (NO₃⁻) is converted into nitrous oxide (N₂O) and lost to the atmosphere). Depending on soil type, temperature, and moisture, nitrogen losses can reach 20–50% or more. Unprotected nitrogen means unpredictable performance, wasted investment, and lost yield potential in your fertility program.
How TSN Protects Your Nitrogen
TSN uses a dual-action protection system combining two proven technologies: NBPT (N-(n-butyl) thiophosphoric triamide) (Inhibits the enzyme urease, reducing ammonia volatilization losses) and DMPP (3,4-dimethylpyrazole phosphate) (Slows nitrification, reducing nitrate leaching and denitrification losses). Together, NBPT and DMPP stabilize nitrogen both above and below ground. You get more nitrogen staying in the ammonium form — stable, available, and plant-usable when your crops need it most, enhancing nitrogen use efficiency.
Proven Agronomic Advantages
Up to 79% Reduction in Ammonia Volatilization (Compared to untreated urea), Up to 18% Reduction in Nitrous Oxide Emissions (Compared to untreated urea), Higher Plant-Available Nitrogen (Less loss means stronger vegetative growth, better tillering, greener canopies, and higher yield potential), Superior Nutrient Use Efficiency (More nitrogen goes into your crop — not the air or groundwater), Best ROI in Nitrogen Management (Protect your investment, maximize your return).
Field-Ready Advantages
TSN is a 46-0-0 urea product built with NBPT and DMPP, ready to be loaded, spread, and seeded with no additional handling or mixing steps. Built with even protection, Works in banded, broadcast, or shallow incorporated applications, Compatible with standard seeding and fertilizer equipment.
