Abstract

Hydrogel technology has become increasingly important in agricultural applications, addressing critical challenges such as water scarcity, nutrient management, and crop sustainability. This research focuses on developing hydrogel seed coatings, emphasising polysaccharides like carrageenan and alginate combined with oligo-chitosan for cross-linking. The study also examines the preparation and swelling properties of carrageenan-alginate hydrogels. Hydrogels offer promising solutions for improving water retention and moisture management, which are key factors in combating the growing problem of water scarcity. Moreover, hydrogels can be designed for controlled nutrient release, enhancing plant nutrient absorption and supporting more efficient agricultural nutrient management. This research seeks to contribute to developing innovative seed coatings that optimise resource use and promote crop growth. The study provides a comprehensive analysis of the preparation process for carrageenan-alginate hydrogels, focusing on the critical role of oligo-chitosan cross-linking in achieving optimal hydrogel properties. The swelling behaviour and characteristics of the hydrogels are thoroughly explored to assess their responsiveness to environmental conditions and suitability for specific agricultural applications. The outcomes of this research can substantially impact agricultural practices by improving crop establishment, yield, and sustainability. By leveraging the advantages of hydrogel seed coatings, this study supports the development of environmentally sustainable and resource-efficient agricultural methods, aligning with the growing demand for resilient and eco-friendly agricultural practices.
