The approximate dry weight of corn silage stored in silos is presented in Table IV and wet weights in Table V . Suggested structures, chop length and screen size for harvesting corn for silage. 15.6 14.3 a Actual weight is influenced by several factors as discussed in text plus the percentage of dry matter from grain. Forage sorghum and grass silage will usually be 5 to 10 percent heavier if stored in the range of 55 to 72 percent moisture. Fill Quickly Filling the silo quickly reduces the time exposed to air and reduces respiration and oxidative losses.
Losses are greatest from slow filling, coarse chop, and lower moisture forages.
Cover with Plastic Covering properly with plastic will reduce top spoilage, and in the drier silages will usually result in improved color, which indicates a reduction in oxidation losses. Prevent pumping air under the plastic and protect the cover from puncture. To eliminate both problems, cover the plastic with low quality chopped forage to a depth of 4 to 6 inches or cover with tires. Chopped forage may be more difficult or impossible to apply and retain on top of plastic covered stacks with steep sides. Consequently, a gradual slope of stack sides will improve preservation.
