This International Day of Zero Waste, we discover the transformative practice of mulching in agriculture, spotlighting its pivotal role in achieving zero-waste farming. Mulching, by utilising organic materials like crop residues or compost, not only enriches soil health and conserves moisture but also reduces waste generation significantly. We explore how this technique minimises the need for synthetic inputs, mitigates erosion, and fosters biodiversity, ultimately illustrating how mulching serves as a cornerstone for sustainable, waste-free agricultural systems.
