Algae-derived agrochemical gel formulations
Innovative polysaccharide composite hydrogel formulations designed for controlled release of agrochemicals. These gels encapsulate nutrients and hormones, allowing for tunable release profiles and enhanced synchronization with plant nutrient demands.
Overview
The algae-derived agrochemical gel formulations offer a novel method for delivering nutrients, fertilizers, and plant hormones through polysaccharide composite hydrogels. This technology provides a controlled release mechanism, enabling precise synchronization with plant nutrient demands. By encapsulating hydrophobic nutrients and hormones, such as 3-indolebutyric acid, within a gel matrix, these formulations can be tailored to degrade and release their contents in response to soil microbial activity, enhancing their efficiency and reducing waste.
Technical specifications
Key features:
- Electrostatic cross-linking of polysaccharides with nutrients for stable encapsulation.
- Nano-encapsulation allows for integration into fabrication workflows like spray coating.
- Proprietary polysaccharide mixtures enable customization of degradation rates and release profiles, adapting to specific agricultural needs.
- Microparticles can be broken down by soil bacteria and fungi, gradually releasing their payloads to match plant growth cycles.
- Suitable for both water-soluble and water-insoluble nutrients, with various analytical methods planned for future validation.
Technology readiness level
Currently at Technology Readiness Level 4, the hydrogel formulations have demonstrated potential in laboratory settings and are progressing towards more extensive validation. Initial tests have shown promising results in controlled environments, and future work will focus on optimizing encapsulation and release kinetics in soil-relevant conditions.
About University of South Australia
Formerly a comprehensive public research university based in Adelaide, UniSA operated multiple city and regional campuses; operations transitioned to the new Adelaide University on January 1, 2026, with an official opening on January 29, 2026. For industry, a one‑stop Enterprise Hub streamlined access to consulting, testing and bespoke training. Co‑located facilities in Adelaide BioMed City (including the UniSA Cancer Research Institute/Bradley Building) enabled close links with hospital partners, while the Mawson Lakes campus adjoined Technology Park to anchor defence and advanced‑technology collaborations. Research was consistently supported by competitive national funding from the Australian Research Council and the National Health and Medical Research Council, often alongside matched industry support. Commercialisation was backed by a dedicated technology transfer function and the Innovation & Collaboration Centre’s incubation and acceleration programs.
