"Using several hundred more kilograms of urea per hectare, but the yield still doesn't increase?" — This is the confusion of many farmers. In China, the traditional urea utilization rate is only 30%-35%, with a large amount of nitrogen lost through ammonia volatilization, leaching, and other forms, which not only wastes costs but also pollutes the environment. How can we make every grain of urea "work to its full potential"? Seaweed-enhanced urea provides the answer!
Role of Seaweed in Urea Enhancement
Seaweed polysaccharides contain a large number of ammonium ion adsorption functional groups, such as hydroxyl and carboxyl groups, which increase the ammonium ion saturation in the soil and reduce volatilization losses.
Seawin seaweed extract products are sourced from the exclusive raw material—Enteromorpha, which is rich in natural seaweed polysaccharides. It is this unique raw material that enables us to deliver significant enhancement to urea, achieving more efficient nitrogen utilization and reducing environmental impact.
Seawinner Seaweed extract is not a simple "additive," but rather reshapes the value of urea through three major mechanisms:
"Navigation" Effect: Seaweed polysaccharides form a protective film, slowing down the decomposition of urea, ensuring that nitrogen release aligns with the crop’s needs (fertilizer effectiveness extended by 15-20 days).
"Acceleration" of Absorption: Bioactive substances from seaweed stimulate root growth, increasing root surface area by 40%↑ and improving nitrogen absorption efficiency by 28%↑ (5 years of trial data).
"Defense" Barrier: Inhibits urease activity, reducing ammonia volatilization by 52%↓; the network structure of seaweed polysaccharides locks in nitrogen, reducing leaching losses by 37%↓ (field monitoring data).

Conclusion
The integration of seaweed polysaccharides into urea is proving to be a game-changer in modern fertilization. By enhancing nitrogen use efficiency, promoting root development, and reducing environmental losses, seaweed-enhanced urea offers farmers a smarter, more sustainable way to boost crop performance. For celery and beyond, this innovation helps maximize yield, improve quality, and increase return on investment — making every kilogram of urea count.
