In some areas, for cultivating shallow roots such as strawberries, Soil Solarization (passive solar heating) or soil disinfection is carried out using chemicals such as methyl bromide.
Plastic sheets are used to protect the disinfectant and prevent its evaporation from the soil. The purpose of using these films is to preserve disinfectants in the soil against pests, diseases, viruses and harmful bacteria.
These films usually last for 2 months and contain UV stabilizer. If the customer needs to improve the product (film) durability, the amount of this additive will be increased.
If the film is used during solarization, an Anti-Drip additive may also be applied to prevent droplets formation on the surface of the film and increase heat transfer to the soil.
