We know that in the agricultural world there are many influential variables if we seek to improve yield, quality of our crops, efficiency of the processes, the use of soils… we could mention several critical factors but on this occasion we want to focus specifically on soil disinfection.
The use of plastics to improve the efficiency in the disinfection of agricultural soils is fundamental as it reduces the amount of necessary chemicals, which turns out to be a great contribution to the environment; plastics that belong to the well-known family of mulching films, which are also used in crops to increase the quality of the harvest or to avoid the excessive use of water. When we talk about plastics for disinfection, the important questions would be: What are the options? How can I choose the most suitable plastic for my crop? Why do I need a plastic for my disinfection process?
First, it is important to mention that disinfection can be done by solarization or fumigation and different plastics are used in each case. Thermal plastics are used for solarization, and barrier-plastics are used for fumigation. In this post, we will talk about a type of plastic used for fumigation disinfection known as TIF or Totally Impermeable Films.
Totally impermeable films (TIF) are manufactured with multilayer technology to incorporate that barrier property into one of its layers and, thus, prevent the toxic gases from the disinfection processes from endangering the health of the workers or shortening the life of our cover plastics.
What advantages does a fully impermeable film (TIF) offer to my crop?
- Increase the effectiveness of the disinfection process by preventing the escape of the gases released from the application of the chemical products.
- Save costs in disinfectants, precisely because we can apply fewer doses and achieve the maximum use of these chemicals. In addition, and as we mentioned before, because the TIF films prevent these toxic gases from shortening the lifespan of greenhouse cover plastics.
- Also, from an economic point of view, by achieving a better concentration of the application of disinfectants and increasing their effectiveness, we can reduce the time necessary for the soil to be fully prepared for planting.
- Reduce environmental pollution, which is becoming increasingly important nowadays in our societies, precisely to promote the fertility of our soil, air quality, and climate control that can also affect our crops, among many other things.
To answer the question about the options available in the market, we must consider plastics manufacturers with the necessary technology to produce multilayer films and with the capacity to formulate their films to add, in addition to barrier properties to the plastic, durability, resistance, flexibility, thermicity, transmission and diffusion of UV rays. The mechanical properties are fundamental because these are plastics that must be manipulated to install them and uninstall them in crops.
A good reference to know that all the variables provided by the technical specifications of these products, whether in terms of disinfection or for any other agricultural use, are the certifications that guarantee the accuracy of the data provided.
One of the options available in the market that meets all these characteristics is:
