The main characteristic of this category of fertilizers is longer retention of the applied Nitrogen in the soil and less runoffs to the deeper layers of the ground, which have significant agronomic and environmental benefits.
Stabilized fertilizers significantly reduce Nitrogen losses, allow plants to utilize it more, minimize its leaching to underground waters, and prevent the contamination of groundwater and basins.
The stabilization of Nitrogen in the soil is achieved through absorption during the process of production of special nitrification inhibitors, in both Nitrogen and compound fertilizers.
Nitrification inhibitors are organic molecules of enzyme activity, which slow down the process of nitrification, reduce the speed of Nitrogen splitting, preventing a fast conversion of the Ammoniacal form into Nitric, and prevent its leaching outside the zone of the roots.
One of the most widely known nitrification inhibitors is Dicyandiamide (DCD), which is included in the Stabilized Nitrogen Fertilizers of HELLAGROLIP with the trade name NutrActive®.
NutrActive® fertilizers, through the DCD nitrification inhibitor, stabilize the Ammoniacal Nitrogen in them, protect it from microbial oxidation, and prolong the time it remains in the soil up to 6 to 10 weeks.
By slowing down the conversion rate of Ammoniacal Nitrogen to Nitric, they adjust the supply of Nitrogen based on the needs of the plants, minimize losses due to leaching and vaporization, and maximize the efficiency of fertilization.
Having an ideal ratio between “stabilized” Ammoniacal and Nitric Nitrogen, NutrActive® fertilizers fully cover both the short- and long-term needs of the plants. This way, they manage a prolonged nutrition of the crops with these two absorbable forms of Nitrogen and they protect both underground and surface waters from the risk of Nitropollution.
