Can agricultural plastic mulch be used to protect crops from frost damage?

Yes, agricultural plastic mulch can be used to protect crops from frost damage. It functions by reducing heat loss from the soil, creating a microclimate that retains warmth around the plants. This insulation effect can help maintain soil temperature above freezing levels, thus protecting the crops from frost. Additionally, plastic mulch can also help to reduce soil moisture evaporation, which can further contribute to frost protection by maintaining soil temperature. It's an effective method in frost-prone areas to safeguard crops and improve yield stability.
