What You'll Learn
Plastic mulch films are used to control weeds and pathogens
Plastic mulch films are extensively used in agricultural practices, including strawberry production. These plastic films are placed at the base of plants and offer several benefits. Firstly, they act as a barrier to control weeds, preventing their growth and limiting their access to sunlight. This weed suppression helps maintain high-yielding strawberry plants that do not require renovation, making it easier to till and restart the soil.
Secondly, plastic mulch films are effective in managing pathogens. By providing a physical barrier, the plastic films reduce the risk of soil-borne pathogens infecting the strawberry plants. This protective layer helps prevent the spread of diseases, promoting healthier plant growth.
Additionally, plastic mulch films offer further advantages to strawberry cultivation. They help reduce water evaporation from the soil, conserving moisture and supporting plant hydration. The films also prevent soil splashing onto the strawberries, keeping the fruit clean and reducing potential contamination.
However, despite these benefits, the use of plastic mulch films has come under scrutiny due to environmental concerns. Studies have found that plastic mulch contributes to long-term pollution and soil degradation. As the plastic breaks down, it releases microplastic and macroplastic particles into the soil, negatively impacting soil quality. These plastic fragments can remain in the soil for decades, affecting soil moisture content, microbial respiration, and plant-available nitrogen.
To address these environmental issues, alternatives to polyethylene-based mulches are being explored, such as biodegradable plastic mulches or natural mulches like straw. While these options provide similar benefits, their higher cost makes them less popular among farmers. Nonetheless, ongoing research aims to improve sustainable agriculture practices and mitigate the environmental costs associated with plastic mulch use in strawberry production.

Plastic helps reduce water evaporation
Plastic is commonly used in agricultural practices to enhance strawberry production. One of the primary benefits of using plastic mulch films around strawberry plants is that it helps reduce water evaporation from the soil.
Water is essential for plant growth and development, and strawberries are no exception. By covering the soil with plastic, farmers can minimize water loss due to evaporation, ensuring that the strawberry plants have access to sufficient moisture. This practice is especially beneficial in regions with limited water resources or during periods of drought, as it helps conserve water and maintain optimal soil moisture levels for plant growth.
The plastic mulch acts as a barrier between the soil and the atmosphere, preventing water vapor from escaping. It traps moisture in the soil, creating a more humid environment for the strawberry plants. This is particularly advantageous for strawberries, as they are shallow-rooted and highly dependent on the immediate surrounding soil for their water needs.
Additionally, the plastic mulch helps control weeds and pathogens, further reducing competition for water. By suppressing weed growth, the plastic ensures that the strawberry plants have access to the available water without having to compete with unwanted vegetation. This, in turn, can lead to higher yields and better-quality strawberries.
While the use of plastic mulch in strawberry production offers these benefits, it is important to consider its environmental impact. Plastic mulch is a form of non-biodegradable waste, and fragments can shed into the soil, leading to long-term soil degradation and pollution. To mitigate these negative effects, some farmers opt for biodegradable mulches or natural alternatives like straw. However, these methods often come with additional costs, making them less popular among farmers.

Plastic prevents soil splashing on strawberries
Plastic is used in strawberry production to support the growth of strawberries. This method is called plasticulture, and it involves covering cultivated and fertilized land with black plastic mulch. The plastic mulch is used to control weeds and pathogens, reduce water evaporation, and prevent soil splashing on the fruit.
Preventing soil splashing on strawberries is important for several reasons. Firstly, soil splashing can spread pathogens from the soil to the fruit, causing disease and reducing the yield of harvestable strawberries. Secondly, soil splashing can cause the fruit to become dirty and less appealing to consumers. By preventing soil splashing, plastic mulch helps ensure that the strawberries remain clean and visually appealing.
In addition to preventing soil splashing, plastic mulch provides other benefits for strawberry cultivation. It helps to suppress weeds, which reduces competition for nutrients and water, and it also acts as a barrier that prevents the spread of pathogens from the soil to the plants. Furthermore, the plastic mulch can help to conserve water by reducing evaporation from the soil, which is particularly important in drought-prone or water-scarce regions.
However, despite these benefits, the use of plastic mulch in strawberry production has come under scrutiny due to its negative environmental impact. Studies have shown that plastic mulch sheds large quantities of plastic fragments that contaminate the soil and persist for decades or longer. These plastic particles, mainly composed of polyethylene, degrade soil quality by reducing soil moisture content, microbial respiration, and plant-available nitrogen. The accumulation of plastic fragments in the soil leads to long-term soil degradation and environmental pollution.
To mitigate the environmental impact of plastic mulch, some farmers and gardeners have adopted biodegradable mulches. These alternatives provide similar benefits to plastic mulch but break down over time, reducing waste and soil degradation. However, biodegradable options are often more costly, making them less popular among farmers. As a result, the search for sustainable and cost-effective alternatives to plastic mulch in strawberry production continues, aiming to balance agricultural needs with environmental conservation.

Plastic is used to automate the picking process
Plastic is used in strawberry farming to automate the picking process and increase yield. The Southeastern plasticulture method, for example, involves covering mounded rows of fertilized and cultivated land with black plastic mulch. A thin hose, or drip tape, is laid under the mulch to provide irrigation and fertilization as the strawberries grow. The plastic prevents the plants from spreading by runners and forming matted rows, keeping them in high production without the need for renovation. This makes it easier to till and restart the process, keeping weeds down.
The use of plastic mulch in strawberry production has several benefits. It can help control weeds and pathogens, reduce water evaporation, and prevent soil splashing on the fruit. However, it is important to note that plastic mulch is also associated with several drawbacks. As a form of non-biodegradable waste, it contributes to environmental pollution and soil degradation over time due to reduced organic matter decomposition and soil biodiversity.
According to a study by California Polytechnic State University, the plastic mulch used in strawberry production sheds large quantities of plastic fragments that negatively impact soil quality. These fragments, mainly composed of polyethylene, can remain in the soil for decades or longer. As the levels of microplastic pollution increase, soil moisture content, microbial respiration, and plant-available nitrogen decrease.
To address the environmental concerns associated with plastic mulch, some farmers and gardeners have adopted biodegradable mulches, which provide similar benefits but break down over time to reduce waste and soil degradation. While these alternatives are more expensive, they offer a more sustainable approach to strawberry farming.
