The mulching technique started in the 50’s and due to its durability, started to be performed with the use of plastic films. It consists of applying the film to the soil surface creating a physical barrier to the transfer of heat and water vapor between the soil and the atmosphere.
Functions

Among the advantages of using plastic tarps in mulching, the following stand out:

Weed control and prevention
Reduction of soil water loss
Micro climate control
Reduction of pests and various infestations
Soil temperature control
Protection of the soil against frost or other climatic agents
Protection from direct contact of fruits with soil
Efficiency in the use of water for irrigation
