Coir-based geocomposite mulch sheet with desired porosity is an innovative agricultural solution made using coir (coconut husk fiber) and bio-based binder. They offer as an environmentally sustainable substitute for synthetic plastic mulch sheets in mitigating carbon footprints. These sheets promote soil health and productivity of crops while contributing to waste management and reducing plastic pollution. Their biodegradability and ability to release fertilizer/water judiciously make them ideal for agricultural applications. The coir-based sheets could effectively retain soil moisture, regulate soil temperature, suppress weed growth and, promoting better plant growth. Their environmental sustainability makes them a desirable choice for farmers seeking to implement advanced organic agriculture practices.
