Northwest Iowa | Raven Industries is were we get our plastic from. They have a product that is oxygen resistant and has string woven in to reduce tearing and keeps the coon and crows from tearing apart. Packing is first an formost the important step for quality feed, then covering and sealing next. 1" of spoilage = 2" of rotted feed, so if you get 6" of rotten on top, you actually lost 12" of good feed. Tires are the most available weight used here, but there are many other things you could use, like sand bags or even just a row of small square bales spaced so the tarp does not blow in the wind. If the tarp is not tight and held down to the feed, air is getting in and you are loseing quality. Hay bales as side walls do let in air, and you will have both rotten silage along the edge and rotten hay bales, I would go without and just make a drive over pile. 6" of removal is minimum in winter and 12" is better when temps start to rise, so long and narrow shaped is better. Just google 'Raven Industries' and see if they have a list of dealers in your area. At $65 per ton corn silage, a few cents invested in covering will pay back big dividends. Figure the tarp size you need and go out were you will make your pile and set some small bales or flags in each of the corners for the packing guy to see. Then as your pile goes up, pull a tape measure over every now and then to be sure you don't get too wide for your tarp. | |
