In a significant stride towards sustainable agriculture, researchers have developed a novel method for producing high-purity nano-hydroxyapatite (CaP), a promising candidate for large-scale nanofertilizer production. The study, led by Thi My Anh Nguyen from the Research Laboratories of Sai Gon Hi-Tech Park, was recently published in the journal ‘Фізика і хімія твердого тіла’.
The research focuses on calcium phosphate (CaP) nanoliquid fertilizers, which have shown great potential in enhancing nutrient uptake efficiency by providing a controlled and sustained release of calcium (Ca) and phosphate (P) ions. The team successfully synthesized highly pure calcium phosphate nanoparticles with a uniform size of a few tens of nanometers using a simple and cost-effective method. This approach incorporates triethanolamine (TEA) as a complexing and stabilizing agent, significantly reducing the synthesis temperature to below 100°C. This reduction in temperature leads to lower energy consumption and production costs while maintaining excellent nanoparticle quality.
The resulting nano-hydroxyapatite (Ca₁₀(PO₄)₆(OH)₂) exhibited a high surface area, promoting gradual nutrient release and improved bioavailability for crops. This straightforward approach offers a scalable and economically viable route for producing advanced nanofertilizers tailored for sustainable agriculture.
The commercial implications of this research are substantial. Traditional fertilizers often lead to nutrient runoff and environmental degradation due to their rapid release rates. Nanofertilizers, on the other hand, provide a controlled release of nutrients, enhancing crop uptake efficiency and reducing environmental impact. The cost-effective and scalable synthesis method developed by Nguyen and her team could revolutionize the agriculture sector by making advanced nanofertilizers more accessible and affordable.
“This method not only reduces the energy required for synthesis but also ensures the production of high-quality nanoparticles,” said Thi My Anh Nguyen. “The potential for large-scale production opens up new avenues for sustainable agriculture, addressing both economic and environmental concerns.”
The research highlights the importance of innovative approaches in agritech, particularly in the realm of nanofertilizers. By optimizing the synthesis process, the team has paved the way for more efficient and eco-friendly agricultural practices. The study’s findings could shape future developments in the field, encouraging further research into low-temperature synthesis methods and the application of nanofertilizers in modern farming.
As the agriculture sector continues to evolve, the integration of nanotechnology offers promising solutions to long-standing challenges. The work of Nguyen and her team exemplifies the potential of interdisciplinary research in driving technological advancements and promoting sustainable practices. The study’s publication in ‘Фізика і хімія твердого тіла’ underscores the significance of their findings, contributing valuable insights to the scientific community and the agriculture industry at large.
