The document discusses the role of mulching and solarization in weed management. Mulching involves spreading a material over the soil to suppress weeds and retain moisture. It can reduce sun damage, provide nutrients, and encourage microorganisms. Solarization uses plastic sheeting to trap heat from the sun and increase soil temperatures, killing weed seeds and soilborne pests. Together, mulching and solarization are effective non-chemical methods of controlling weeds through blocking sunlight from seeds and heating the soil to terminate seeds and pests.
