Summary:
Sheep wool presents growing management and disposal challenges, particularly as landfill regulations become more stringent. However, sheep wool is a biodegradable fibrous matrix, rich in nutrients and capable of retaining significant amounts of moisture. These properties make sheep wool a promising candidate as a renewable soil amendment, with the potential to improve soil physio-chemical properties, enhance crop productivity, and increase water-use efficiency. To explore these benefits, different rates of wool will be used as a soil amendment under various irrigation scenarios. The study will measure the effect of wool application on crop growth and development, soil health, and water-use efficiency. These metrics will be used to evaluate the sustainability and long-term viability of integrating wool into agricultural production systems.
