Silage wraps have been around for centuries and have proven to be an effective and cost-effective baler. They are generally made from a combination of resins and a binder, typically a silica resin or binder. The resin is mixed with a binding agent like lime, clay, or sand, which helps to hold the shape of the plant cell walls in place. When heated, the liquid binder is released, and the sheet becomes a tight sheath.
The silage wrap can be rolled into various shapes to create a variety of designs and colours. The design is rolled onto a bale and tightly wrapped around the plant cells, where the bale is then burned to burn away. The thermal energy released during the burning process heats the air inside the bale to oxygen levels, making it easier to breathe. The closed-cell foam allows this airflow to penetrate deeper into the root system while keeping in fresh oxygen.
As the plant cells absorb oxygen, silage wrap provides a rich source of nutrition for the crop through the complete digestive process. During this process, silica produces long chains of amino acids that feed the crop through transpiration. The longer the length of the chain, the higher the concentration of these necessary nutrients in the crop.
The silage-wrap also provides a medium in which vital nutrients can penetrate the crop through peristalsis, the process by which plant cells discharge water and other elements into the air. The wrap provides a continuous pathway of air and moisture to the root system during the drying process.
The silage wrap also reduces the amount of moisture present in the soil. It does this by restricting the permeability of the soil to reduce moisture exchange between the soil and the crop. This prevents the moisture from evaporating into the air or seeping in through the soil’s surface. Also, during transportation, hay is often wrapped or packed for protection against pests and disease. Also,the wrapping provides a low-tech way to contain the wet material during storage without adding any additional moisture to the soil. This prevents the bales from blowing away in high winds or being damaged by exposure to too much rain or snow.
There are several ways to prepare the plant material before using silage-wrap layers. Most farmers use old-fashioned irrigation systems that include a water sprayer attached to a pipe with a long hose. This spray, called hydro-spray, applies fertilizer by compressing the air directly to the soil.
Old-fashioned irrigation systems didn’t have valves, so a slow drip of the water applied to the soil would wash out some fertilizer. Modern systems can control the application of fertilizer by controlling the speed of the spray or simply by changing the nozzle and spraying no more than a precise amount at a time.
Another method farmers use to prepare silage wrap for use in modern farms is the net wrap system. The net wrap system makes use of two plastic film layers placed over a pre-prepared silage layer. The second plastic film layer is placed on top of the first, trapping moisture within the first plastic film layer. Then the moist plastic film is stretched tightly over the top of the initial layer. Silage is then ready to be sprayed when needed.
