N Protect™ Range
Enhanced Efficiency Fertilizer Additives
What’s the biggest challenge for Nitrogen Fertilizer? Most is lost before it reaches the target
Nitrogen is the most important crop nutrient. It is critical to the plant growth and quality. However, only a fraction of the Nitrogen applied in the field is absorbed by the plants at the expense of the environment.
Nitrogen fertilizers suffer from volatilization above ground as well as leaching into groundwater leading to significant Nitrogen loss.
AgRHO® N Protect™ Range addresses this challenge
AgRHO® N Protect™ is a patented range of eco-friendly Nitrogen stabilizers leveraging Solvay’s expertise in Green Solvent technology and Agrochemical formulations.
N Protect™ range increases farmer’s return on investment
Nitrogen stabilizers such as urease and nitrification inhibitors help to protect farmer’s investment in Nitrogen fertilizers. They increase the amount and the time that Nitrogen remains in the soil, available for the plant absorption.
Solvay has the global footprint to deliver world-class services
AgRHO® N50 Protect™ is a revolutionary, patented urease inhibitor formulation that delivers a 50% load of NBPT (N-(n-butyl)thiophosphoric triamide) reducing ammonia volatilization once applied to urea based fertilizers in a non-toxic solvent formulation, whereas the benchmark in the market is having up to 30% NBPT concentration in the liquid. Thanks to this achievement our customers spend less, and consequently, save more money.

On the soil, above ground, urease enzyme degrades urea into volatile ammonia. Up to 40% of urea can be lost through ammonia volatilization. NBPT inhibits the urease enzyme by competitive inhibition: NBPT which resembles urea, binds to the active site of the urease enzyme and prevents the urea from binding.
Below ground bacterias turn ammonium into nitrate. Up to 30% of Nitrogen can be lost through nitrification. DCD is a bacteriostatic. It prevents the multiplication of the bacterias which participate to the nitrification.
DCD is more gentle to the environment. It is not a bactericide; it doesn’t kill the bacterias. It is a bacteriostatic. It prevents for multiplication for a while. Moreover Solvay invented the solubilized DCD which is more efficient than conventional powder DCD. It delivers the same performance with 5 times less DCD. This is why AgRHO® NH4 Protect™ is the single Nitrification Inhibitor approved by the French authority ANSES with the AMM n° 1170075.
Solubilized NBPT / DCD in a liquid formulation is safer to use, easier to use and more efficient. Safer to use because there is no risk of inhalation. Easier to use because it’s easier to apply a liquid rather than a powder on fertilizer. More efficient because the liquid formulation achieves an homogeneous coating and penetrates deep into the granule.
Price depends on the grade and the ordered quantities. The ballpark premium charged to the grower at farmgate is 10% to 20% of the conventional fertilizer value.
Use rate depends on the grade and on the Nitrogen content of the fertilizer. It can go from 1 kg to 6 kg per metric ton of fertilizer.
NBPT based solutions such as AgRHO® N Protect™, AgRHO® N50 Protect™ and AgRHO® N-Dual Protect™ are relevant for urea and UAN. They can also be applied on some blends of urea with other nutrients. Your Solvay representative can advise you in that matter. DCD based solution AgRHO® NH4 Protect™ can be applied on any fertilizer containing either urea or ammonium.
