Environmental concerns in the long run have led the public to develop alternative materials that could be used in agriculture. The development and application of carrageenan and wheat straw biodegradable composite in agriculture is the main focus of this study. This composite is crafted to tackle the environmental repercussions linked with traditional agricultural materials. The manufacturing procedure encompasses the extraction and treatment of wheat straw fibres, which are then merged with carrageenan, a naturally occurring polysaccharide sourced from red seaweed Furcellaria Lumbricalis. The resultant bio composite displays encouraging mechanical traits, rendering it suitable for a variety of agricultural applications. The employment of wheat straw not only offers an environmentally conscious substitute but also addresses the predicament of disposing of agricultural waste. Regarding its application, the biodegradable composite can serve as a material for seedling trays. Due to the composite natural propensity to break down over time, long-term environmental pollution is prevented. Additionally, the material biodegradability is improved by its contact with soil microbes, enhancing the overall sustainability of agricultural methods. The outcomes of this study underscore the potential of the biodegradable wheat straw and carrageenan composite as a sustainable substitute for diverse agricultural applications. The development and assimilation of such environmentally friendly materials contribute to the ongoing endeavours to promote sustainable practices in agriculture, addressing both ecological apprehensions and the necessity for pioneering solutions in the field.
