NewzA USDA-funded trial has demonstrated that utilizing cardboard as a base for garden beds significantly reduces weed coverage, reaching as low as 15% by the second growing season. The study compared these cardboard-layered beds against traditional tilled soil methods to evaluate their effectiveness in weed suppression.
Beyond the reduction in weed density, the trial indicated that the cardboard method simplifies the weeding process for farmers. By improving efficiency and reducing the labor required for weed control, this technique offers a potential alternative for managing crop yields in agricultural settings.
