🌾 Silage Bag Capacity Calculator
Calculate tons capacity, dry matter, and days of feed for ag bags and silage bags by diameter and length
| Silage Type | Typical Density (lbs/cu ft) | Typical DM% | Tons per 1,000 cu ft |
|---|---|---|---|
| Corn silage | 40-45 | 28-35% | 20-22.5 tons |
| Grass / haylage | 35-42 | 35-50% | 17.5-21 tons |
| Alfalfa silage | 38-45 | 35-45% | 19-22.5 tons |
| Sorghum silage | 38-44 | 28-35% | 19-22 tons |
| Small grain silage | 35-42 | 30-40% | 17.5-21 tons |
| Bag Length (ft) | 9 ft Bag Volume (cu ft) | Corn Silage Tons | Haylage Tons |
|---|---|---|---|
| 100 ft | 5,726 | ~103 tons | ~81 tons |
| 150 ft | 8,590 | ~154 tons | ~122 tons |
| 200 ft | 11,453 | ~206 tons | ~163 tons |
| 250 ft | 14,316 | ~257 tons | ~204 tons |
| 300 ft | 17,180 | ~309 tons | ~244 tons |
| 400 ft | 22,906 | ~412 tons | ~326 tons |
| 500 ft | 28,633 | ~515 tons | ~407 tons |
Silage bags give practical ways to store forage on the farm without need to build bunkers. Some of them store around 200 tons or even more each bag and they seal the content so that outside it stays clean. Many farmers wonder how much silage genuinely entered in bag.
To estimate the capacity of silage bags, you can count the volume of the bag and multiply it by the density. The amount of dry matter in it matches the volume multiplied by the density of dry matter. This density ranges according to the machine and settings of every bag, depending on the kind of forage.
How Much Silage Fits in a Bag
Its standard range are between 11 and 15 pounds of dry matter for cubic foot.
The real capacity adjusts according to the moisture of the content, the length of the cut and the density during filling. In 100-foot bag of 8 feet of diameter with 65 percent corn silage, you estimate around 100 wet tons in 14 pounds for cubci foot. That coincides with the experiences of many farmers.
Average big bag size stores 100 to 150 tons according to wet base, although the internal density of the silage affect the total amount. For haylage in 12-foot bag, some farmers use the number of around 0.9 tons of dry matter each foot of filled bag, but it matters to check by weights and know the usual moisture of haylage for reach accuracy.
Easy weights of forage before unloading help to best manage the capacity. Available sheets and calculators designed for producers estimate the amount in silage bag. They count the geometric volume after input of the right data, so the use of physical space for silage.
Farmers around the world commonly consult the measures of university extension services for target compaction of crops.
Silage bags happen in various sizes. Often silage bags are available with diameter of 6 to 14 feet. Some are made of polyethylene, in black or white variants.
Certain brands apply seven-layer blown polyethylene sheet for more strength. These bags resist tears, punctures and UV-radiation more than some competitions. They have big open port, which eases and boosts the load in the tunnel of the bagger, while giving more space for fill the silage.
Many coincide with all silage baggers, grain baggers and extractors for high-capacity grain bags.
Silage bags adapt to changing needs of forage storage on the farm, so they answer for producers that want to expand or shrink according to years.of
