There are many types of silage covers. The two most common types of NetWrap silage covers are the pergola cover and the stand-pipe silage cover. Pergolas and stand-pipe silage covers are easy to construct. In fact, it is likely that you already have the materials and tools for these types of silage covers. Stand-pipe silage covers are more difficult to build.
Silage preparation begins with a thorough cleaning of the area used for the silage making process. The area must be completely free of all debris. This includes leaves, twigs, sticks, needles, and any other type of debris that might be floating around in the ambient air. This is also the time to remove all rubbish from the area. This will ensure good circulation of air throughout the silage making chambers while it is being made. You will also want to check for leaks, which could lead to oxygen deprivation and possibly the start of some disease.
Once the area has been cleaned up and any debris removed, you can begin to constructing your silage covers. These sheets are made of high quality, wicking cotton that is woven tightly. Most silage covers consist of ten or twelve sheets, but depending on the number of materials you are using, you can use as few as six.
A layer of this cotton will be placed inside the silage making chamber to present the airtight covering. This is usually done on the inside of the cover. The constructed cover will help the silage retain moisture while allowing the natural air circulation to keep the moisture levels within the silage covers relatively low. However, if the amount of moisture in the covering piles up to an unhealthy level, the silage can become damp. This is not always the case, and some farmers find that dampness can increase losses.
When you have your NetWrap silage covers constructed and ready to install, you should test the installation by putting the cloth through the opening several times. If it shrinks in size when it comes out, it is time to reinforce the corners with staples. However, if the drying period hasn’t yet started, and the film still doesn’t seem to be expanding, then you may need to wait a few days before it is ready to be installed. Besides, when you are making your own silage films, you should check the manual to see if you need to preheat the chamber. This can reduce the drying time significantly.
Silage film is an advantageous product that can be made at home. Its unique properties allow it to absorb moisture quickly, provide excellent protection from insects and reduce losses due to dampness. However, when making your own, you should consider the factors mentioned above, especially the ventilation. You can add this dimension to your own system to ensure that silage covers provide a completely airtight seal to the soil and that no moisture can escape. The added benefit of using this kind of system is that it is completely green. Using natural materials instead of plastic or other synthetic materials will make your system more environmentally friendly.
