Plastic is cheaper and easier to assemble than glass
Farmers use plastic covers to improve crop quality, increase production levels, and obtain better results to meet the world's food demand. Plastic covers are used in greenhouses to establish crops in seasons and areas where it was previously impossible to cultivate, by creating microclimates within the structures that enhance the production of fruits, flowers, and vegetables.
Before the use of plastic, glass structures were used in greenhouses, which were expensive, difficult to assemble, and inefficient for crops. Glass structures often caused burns on plant leaves and fruits and quickly lost temperature at night. Plastic covers, on the other hand, are cheaper and easier to assemble. They also have protective qualities for crops, plants, and soils, especially from external climatic agents.
The use of plastic covers in greenhouses allows farmers to control the temperature and create optimal conditions for plant growth. The plastic traps the heat inside, making it beneficial in colder climates. Additionally, the type and color of plastic used can be chosen to optimize the passage of light through the greenhouse, affecting the accumulation of certain compounds in the plants and influencing their aesthetics. For example, specific covering materials are designed for commercialized flowers like red roses to achieve the desired color and growth.
The use of plastic mulches, which are spread over the fields, has additional benefits. Plastic mulch suppresses weeds, conserves water, and aids plant growth. It acts as a barrier to keep methyl bromide in the soil and prevents the crusting effect of rain and sunlight, maintaining loose and well-aerated soil. Plastic mulch also brings on early fruiting and restricts weed infestation, leading to improved overall growth.
While plastic has its advantages, it also comes with challenges. The disposal of plastic mulch is an environmental concern, and the large amounts of plastic used in agriculture contribute to waste. Biodegradable plastic could be a solution, but there are worries about its long-term effects on soil health and the environment. Additionally, the use of plastic mulch requires specialized equipment for installation and removal, adding to the costs.

Plastic protects crops, plants, and soil from external climatic agents
Plastic is used by farmers as a protective covering for crops, plants, and soil. It is used as a mulch and in greenhouses and poly tunnels.
Plastic mulch is a product used in a similar fashion to traditional mulch to suppress weeds and conserve water in crop production and landscaping. Plastic mulch is often used in conjunction with drip irrigation. It is spread over fields and held down with soil, blocking sunlight from hitting the ground and stimulating weed growth. This allows plants to grow unimpeded. It also decreases the crusting effect of rain and sunlight, keeping the soil underneath loose and well-aerated, and protecting it from erosion.
The use of plastic mulch can lead to an improvement in the overall growth of plants. It promotes growth, conserves moisture, brings on early fruiting, and restricts weed infestation. It is also used to retain a few extra degrees of heat at night, allowing crops to be established in seasons and areas where it was previously unthinkable to cultivate.
However, plastic mulch has disadvantages. It is expensive, and the removal and correct disposal of plastic mulch are technically and economically burdensome. It is also unsustainable as it is a petroleum-based product and difficult to recycle. Biodegradable plastic is a possible solution, but some worry about its long-term effects on soil health and the environment.

Plastic mulch suppresses weeds, conserves water, and aids plant growth
Plastic mulch is a product used in agriculture to suppress weeds, conserve water, and aid plant growth. It is a form of plasticulture, similar to traditional mulch, and is often used in conjunction with drip irrigation. Plastic mulch is predominantly used in large-scale vegetable farming, with millions of acres cultivated under plastic mulch each year.
Plastic mulch suppresses weeds by blocking sunlight from hitting the ground and stimulating weed growth. This creates a practically weed-free area around the plant, removing the need for cultivation except between the rows of plastic. The soil underneath the plastic stays loose and well-aerated, and the mulch protects it from erosion. Weed control between beds of plastic can be achieved using directly applied herbicides and through mechanical means.
Plastic mulch conserves water by decreasing the crusting effect of rain and sunlight. It also promotes plant growth by conserving moisture, bringing on early fruiting, and restricting weed infestation. Certain plastic mulches also act as a barrier to keep methyl bromide, a powerful fumigant and ozone depleter, in the soil.
The use of plastic mulch can lead to improved plant growth overall. However, there are also disadvantages to using plastic mulches in crop production. The benefits come at a higher cost than planting in bare soil, and the disposal of plastic mulch can be an environmental problem. While biodegradable plastic could be a solution, some farmers worry about its long-term effects on soil health and the environment.

Plastic creates a microclimate that enhances the production of fruits, flowers, and vegetables
Plastic covers have been used for decades by farmers worldwide to improve crop quality and increase production levels. One of the primary benefits of using plastic covers is the creation of a microclimate that enhances the production of fruits, flowers, and vegetables.
Plastic agricultural covers, typically used in greenhouses or tunnels, help establish crops in seasons and regions where cultivation was previously impossible. They achieve this by creating a microclimate within the structure that promotes the optimal growth of various crops. The microclimate is influenced by factors such as temperature, light, and humidity, which can be regulated by the plastic cover.
The plastic covers retain a few additional degrees of heat at night, providing a warmer environment for the crops. This is especially beneficial in colder climates, as the plastic traps the heat inside, aiding in the growth of temperature-sensitive crops. Additionally, the plastic covers can be designed with specific optical properties to optimize light transmission. For example, in flower crops, the right colour and properties of plastic can enhance the accumulation of anthocyanins and flavonoids, resulting in more vibrant and aesthetically pleasing flowers.
The use of plastic covers also helps conserve moisture, promoting the growth of crops and bringing forward the fruiting season. By covering the soil, plastic mulch decreases the crusting effect of rain and sunlight, keeping the soil underneath loose and well-aerated. This also creates a weed-free area around the plant, reducing the need for mechanical cultivation and herbicide use.
While plastic covers offer significant advantages in crop production, there are also challenges associated with their use. The accumulation of plastic waste in soils and the environment is a significant concern, and the disposal and recycling of plastic mulch can be technically and economically demanding. Additionally, the cost of plastic covers and the specialized equipment needed for their installation and removal contribute to higher expenses for farmers. Despite these drawbacks, plastic covers continue to play a crucial role in agriculture by creating favourable microclimates that enhance the production of fruits, flowers, and vegetables.
