Introduction

In the agriculture industry, plastic sheeting is commonly used as a tool to enhance crop growth and yield. Its purpose is to provide a layer of protection, reduce water evaporation, and control soil temperature. However, a common question remains, how does water get to plants when using plastic sheeting? In this article, we will explore the different methods used to ensure that plants receive the water they need to grow and produce a successful harvest.

Irrigation

Irrigation is the process of supplying water to plants at regular intervals. There are different methods of irrigation available, including surface irrigation, drip irrigation, and sprinkler irrigation.

In the case of plastic sheeting, drip irrigation is a popular method. Drip irrigation involves laying tubing underneath the plastic sheeting, which delivers water to a specific spot near the plant's roots. This method is preferred because it prevents unnecessary water evaporation and saves water.

Capillary Action

Capillary action is a natural phenomenon where liquid is drawn into narrow spaces or pores, such as the soil. When using plastic sheeting, the covering creates a seal that traps moisture in the soil. Over time the moisture will be drawn up by capillary action to the plant's roots, where it's absorbed and utilized by the plant.

Cutting Irrigation Holes

Another method used to deliver water to the plants is by cutting irrigation holes in the plastic sheeting itself. The holes allow water to go directly to the planting area. This is a simple yet effective solution that doesn't require special equipment or tools.

Moisture Wicking from Soil

Similar to capillary action, moisture wicking from the soil occurs when moisture is drawn up from the soil to the plant roots. The plastic sheeting itself can act as a barrier, trapping moisture in the soil, where it's available for the plants to use.

Mulching

Mulching is the process of adding a layer of material, such as straw or leaves, to the surface of the soil. The mulch helps to retain moisture, reduces evaporation, and suppresses weeds. Mulching can be used in conjunction with plastic sheeting, which creates an additional layer of protection against moisture loss.

Conclusion

Plastic sheeting is a reliable tool that can significantly improve crop growth and yield. However, ensuring that water is delivered to plants when using plastic sheeting requires additional measures. Various methods, such as drip irrigation, capillary action, cutting irrigation holes, moisture wicking, and mulching, can be used to ensure plants receive the required water. By implementing these measures, farmers can experience the benefits of using plastic sheeting while ensuring the health and growth of their crops.
