Advantages and Disadvantages of Silage Pit Covers

When it comes to silage covers, there are a few things that you should look for. These include Low transmission oxygen barrier film, Airtight seal, UV resistance, and reusability. In addition, you’ll want to ensure the cover is recyclable, which is important if you plan to use it again. If you’re unsure what to look for, read on to learn more about silage pit covers.

Low transmission oxygen barrier film

silage coversAccording to embodiments of the present invention, the film is suitable for covering silage pits and provides an anaerobic atmosphere to preserve energy and nutrients in the feedstock. Specifically, it should be capable of forming an oxygen and gas barrier. Oxygen barrier properties can be measured with known standards such as DIN 53380-3 and ASTM D3985. In addition, the oxygen transmission rate should be less than 10 000 cm3/m2/24 hours.

The OTR is an important factor to consider when selecting a cover. A silage pit that contains less than 25% DM is likely to suffer dry matter losses. Using an oxygen barrier film reduces the possibility of odours in the top metre of the hay. The OTR of a silage pit cover measures the protection a film can provide. Using an oxygen barrier film is a cost-effective solution. Check out https://www.silagewrap.com.au.

Airtight seal

When purchasing silage covers for a silage pit, the most important feature is an airtight seal. It means that the pit’s edges cannot be billowed, which would cause air to be pumped into the silage and accelerate its spoilage process. Typical weights for pit covers are used tires placed close to each other and weighed down by sandbags or soil. The number of tires needed to weigh down the plastic can be calculated by dividing the silage storage area by six and ensuring that each tire touches all sides.

There are many silage sheets today, and some are branded. Some are cheaper, while others are branded. They generally fall into three categories: black plastic sheets, clear plastic sheets, and biofilms. While black plastic sheets are water-resistant, they are not airtight and can transmit large air into the pit. So, to be sure, you should never use black plastic to cover your silage pit.

UV resistance

The best silage covers are polyethylene (PE) rather than PVC. Not all types of PE have the same benefits, though. RPE offers the best chemical and UV resistance. BTL’s silage pit covers are made from LDPE and HDPE. They combine the benefits of both polymers for a better product. In most cases, RPE is preferred over PVC.

Unlike PVC, ARK Silage Tarps are made from a non-woven material that protects against UV radiation. These covers have a silver top side and dark underside. They block UV rays while still allowing air to pass through. In addition, these covers are waterproof and UV resistant and will not peel or disintegrate in the sun. Finally, they are durable, which is a great feature to protect your hay. Check out https://www.silagewrap.com.au.

Reusability

The traditional polythene and tyre method is not perfect and messy. There is also the risk of oxygen seeping through the rips and spoiling the silage, causing loss of feed and money. Several manufacturers have come up with alternative covering systems to counter this problem. But how do they work? Here are some of the advantages and disadvantages of reusable silage pit covers. Listed below are some of the most notable ones:

Cost

Adding a silage pit cover is an effective way to keep your winter feed in tip-top shape. While it may be expensive to cover a pit with plastic, there are many benefits to a reusable silage pit cover. Unlike plastic, silage pit covers are recyclable and last for years. As a result, a silage pit cover costs less than ten years of plastic covering. It also protects your feed from spoilage and waste, minimising losses.
