Modified Phosphorous Containing Particles (RFT-700)
Invention Summary
Traditional fertilizers often suffer from low nutrient use efficiency, leading to significant environmental challenges such as eutrophication and greenhouse gas production. This invention addresses these issues by introducing a more efficient delivery system for fertilizer components, primarily phosphorus. This technology revolves around a novel multi-layered particle design, utilizing a core-and-shell configuration that optimizes nutrient delivery. Each particle comprises a core that can include essential fertilizing elements like phosphorus, nitrogen, or potassium, surrounded by multiple layers made from various materials including polysaccharides like chitosan and polyanionic polymers like poly(citric acid). These layers can be tailored to control nutrient release rates, enhancing efficiency and reducing environmental impact.
Benefits
- Enhanced Nutrient Efficiency-the layered design allows for a slow and controlled release of nutrients, which increases absorption by plants and reduces waste.
- Environmental Protection-by mitigating runoff and leaching of fertilizers, this technology helps prevent eutrophication and pollution of water bodies.
- Versatility-the particle's design is adaptable to include various nutrients based on specific crop needs and soil conditions
- Reduced Usage Rates-higher efficiency allows for lower quantities of fertilizers to be used, reducing costs and environmental impact
Applications
- Agricultural Crop Production
- Gardening and Landscaping
