Urea–nanocellulose hydrogel for enhanced nitrogen use efficiency
Innovative urea–nanocellulose hydrogel formulation boosts nitrogen use efficiency, reducing fertilizer loss and improving plant growth through controlled release and enhanced uptake.
Overview
The urea–nanocellulose hydrogel is an innovative solution designed to enhance nitrogen use efficiency in plants. By integrating urea into a methyl nanocellulose hydrogel, this technology offers a sustainable method to minimize fertilizer losses and improve plant growth. Traditional urea dissolves quickly, often leading to significant leaching and volatilization. In contrast, this hydrogel formulation allows for controlled release, moisture retention, and better foliar adhesion, promoting enhanced nutrient uptake and reduced environmental impact.
Technical specifications
The hydrogel is formed by combining urea with methyl nanocellulose (MCA), an amphiphilic carrier synthesized through a cost-efficient catalytic oxidation process. MCA is biocompatible and does not exhibit antimicrobial activity, making it suitable for use in living systems. The resulting nano-urea hydrogel offers controlled nutrient release and superior water retention. When applied via foliar spray, it modulates urea release kinetics, reduces environmental losses, and promotes nutrient assimilation. Preliminary studies have demonstrated increased carotenoid levels in plants, indicating improved nutrient uptake.
Technology readiness level
This technology is currently at TRL 4, having been validated in laboratory settings with plans for further validation through proof-of-concept experiments. The research focuses on demonstrating improved release kinetics, plant uptake, and physiological responses compared to conventional urea application.
