How Mulching Sheet is Used to Control Weeds in Fields?

Everything You Need To Know About Mulching Sheet

There are many options available for farming in order to control weeds in the fields. Of course, many follow different procedures. But the question is whether all those procedures can be effective for all conditions, especially in bad weather and weeds. The answer is No. Growing vegetables commercially on farms requires intensive management. Among the challenges, the weather is the major constraint, as mentioned above and the weeds.
So, in this blog, let’s find an interesting way to control weeds in fields and also a lifesaver in bad weather – an AGRICULTURE MULCHING SHEET.
The complete guide to choosing the best mulching sheet for your agricultural and garden requirements. Let’s get started.
Mulching Sheet Used to Control Weeds

What is Mulching Sheet?

Agriculture mulching sheet, also known as plastic mulch or ground cover, is a polyethene material used to cover the soil surface in agricultural fields. It is commonly used in farming to suppress weed growth, conserve moisture, and increase soil temperature.
The mulching sheet is spread over the soil and secured with soil anchors or weights to prevent it from blowing away. It comes in different colors, such as black, white, and transparent, and can be either opaque or perforated. Black mulching sheets are preferred in most cases because they absorb more sunlight, which helps to warm the soil and promote plant growth.

Some Benefits of Using Mulching Sheet in Agricultural Farming

Weed Suppression:

Mulching sheets help prevent weed growth by eliminating sunlight and inhibiting photosynthesis. This helps reduce competition for nutrients, water, and sunlight between crops and weeds, improving crop yields and quality.
Moisture Conservation:
Mulching sheets help to reduce water loss from the soil surface by reducing evaporation and runoff. This helps to conserve moisture and improve soil water availability for crops. Additionally, the reduced weed growth helps to reduce the demand for water in the field, as weeds can consume a significant amount of water.
Soil Temperature Regulation:
Mulching sheets can help to regulate soil temperature by absorbing and retaining solar radiation. This can help warm the soil, accelerating plant growth and crop maturity.
Reduced Herbicide Use:
By suppressing weeds, mulching sheets can help to reduce the need for herbicides, which can be costly and have negative environmental impacts.
Improved Soil Health:
Mulching sheets can help to improve soil health by reducing soil erosion, maintaining soil structure, and reducing the risk of soil-borne diseases and pests.
Overall, using mulching sheets in farming can provide several benefits for weed control and crop production, while also reducing the environmental impact of farming practices.
Black Plastic Film
Many medium- to large-scale conventional and organic vegetable farms prefer to utilize black plastic film mulch in conjunction with in-row drip irrigation for weed control. The opaque coating can improve crop growth by preserving soil moisture, encouraging soil warming, and accelerating the mineralization of nutrients from soil organic matter.
It also decreases the germination of light-responsive weed seeds, shadows out and physically stop the emergence of most weeds. The benefits of crop growth aid in weed management by improving the crop’s capacity to tolerate and outcompete weeds.
The most affordable and extensively used synthetic mulches are plain or embossed black polyethene films, which are available in rolls up to 2,500 feet in length and a variety of widths (4 feet is the most typical) and thicknesses (0.8-1.25 mil). Typically, a tractor-drawn mulch layer is used to spread the plastic evenly across crop rows or raised beds, securing the mulch’s borders with soil.
Warm season crops like tomatoes, peppers, eggplant, melons, sweet potatoes and okra are frequently planted on raised beds mulched with black plastic. This method is occasionally employed for early plantings of cool season crops like lettuce, onions, brassicas, and onions. In order to transfer moisture and nutrients (liquid organic fertilizer) directly to the crop without watering and feeding between-row weeds, drip pipes are typically put under the film (either on or below the soil surface).

Difference Between Black Plastic Film Vs Plastic Mulching Sheet

Black Plastic Mulching Sheet  
  • Can be mechanically applied to multi-acre fields with widely available equipment.
  • Eliminates the light stimulus for weed seed germination over most of the planting bed.
  • Blocks emergence of most weeds.
  • Conserves soil moisture present at the time of installation or provided by drip lines under the mulch.
  • Reduces nutrient leaching by letting rainwater run off too much.
  • Increases soil temperature by a few degrees, fostering crop growth and maturation in the early growing season.
  • Maintains the cleanliness of vegetable crops’ edible parts, particularly pumpkins and other fruiting vegetables.
Plastic Mulching Sheet  
  • It is manufactured from petroleum, a non-renewable resource.
  • It does not provide organic matter to feed the soil.
  • Does not provide a good habitat for ground beetles, earthworms, and other beneficial organic mulches.
  • It does not breathe, excludes rainfall, and requires drip irrigation to ensure adequate moisture.
  • Weeds that appear via planting holes may need to be manually removed.
  • It can be broken down by nutsedges and a few other weeds with hard, sharp growth points.
  • calls for cultivation or other weed-control measures in alleys.
  • On sloped fields, it can channel water and exacerbate between-bed erosion.
  • At the conclusion of the season, it must be collected and disposed of (200–300 lb/ac) produces a lot of plastic garbage.

Types of Other Plastic & Other Agricultural Mulching Sheet Materials Available

There are numerous varieties of mulch material. Wider options are available, with typical widths ranging from 36 inches to 60 inches. There are thickness ranges from 0.6 mil and 2 mil or more. The material’s surface texture might be shiny or embossed. Plastic that has been embossed seems wrinkled because of the surface’s visible patterns.
Comparatively speaking, this mulch is more resilient to damage brought on by cracking, wind stress, and punctures than non-embossed mulches. A different kind of mulch called linear low density has a smooth surface appearance but may also have what appear to be parallel lines running through it. These parallel lines intersect to create diamond-shaped patterns.
Black, white, and white on black are the most typical agricultural mulches, which can be applied with either side facing upward, depending on the situation. When soil needs to warm up quickly, clear mulch is utilized; however, because weeds can grow underneath it, its utility is constrained. When soil cooling is desirable, such as when planting autumn crops in the sweltering summer, reflecting mulch made of white or aluminum is utilized.
