However, this may be a disadvantage for items like chopped wood. Bottom silo unloaders are utilized at times, but have problems with difficulty of repair.Īn advantage of tower silos is that the silage tends to pack well due to its own weight, except in the top few feet. Tower silos containing silage are usually unloaded from the top of the pile, originally by hand using a silage fork-which has many more tines than the common pitchfork 12 vs 4-and in modern times using mechanical unloaders. Silos can be unloaded into rail cars, trucks or conveyors. Silos storing grain, cement and woodchips are typically unloaded with air slides or augers. Wood staves, concrete staves, cast concrete, and steel panels have all been used, and have varying cost, durability, and airtightness tradeoffs. Storage silos are cylindrical structures, typically 10 to 90 ft (3 to 27 m) in diameter and 30 to 275 ft (10 to 90 m) in height with the slipform and Jumpform concrete silos being the larger diameter and taller silos. Types of silos Tower silo Concrete stave silo under construction in 2015 Three types of silos are in widespread use today: tower silos, bunker silos, and bag silos. Silos are commonly used for bulk storage of grain, coal, cement, carbon black, woodchips, food products and sawdust. Silos are used in agriculture to store fermented feed known as silage, not to be confused with a grain bin, which is used to store grains. Silos in Acatlán, Hidalgo, MexicoĪ silo (from Ancient Greek σιρός ( sirós) 'pit for holding grain') is a structure for storing bulk materials. Grain bins in Cashton, Wisconsin Grain elevators are composed of groups of grain silos, such as these at Port Giles, South Australia.

In the peach cells, the spreadsheet calculates corn grain equivalents of 7,436 bu for the snaplage, 5,125 bu for the HM ear corn and 8,796 bu for the HM corn, for a total of 7,436 + 5,125 + 8,796 = 21,356 bu of corn grain equivalent.This article needs additional citations for verification.Feed densities were left at respective default values of 35, 40 and 45 lbs of DM per cubic ft.HM corn: 9,249 cubic ft of high moisture corn in a silo bag (8 ft bag, 200 ft of plastic, tied off at both end with 8 ft of bag = 184 ft of bag length).HM ear corn: 6,736 cubic ft of in a silo bag based on the calculator (8 ft bag, 150 ft of plastic, tied off at both end with 8 ft of bag = 134 ft of bag length).Snaplage: 12,566 cubic ft in a silo (20 ft diameter x 40 ft filled height) based on the calculator.On January 15, 2020, estimated volume of inventory was.In the peach cells, the spreadsheet calculates corn grain equivalents of 17,582 bu for the snaplage, 1,111 bu for the HM ear corn and 3,085 bu for the HM corn, for a total of 17,582 + 1,111 + 3,085 = 21,779 bu of corn grain equivalent.Dry matter percentages are 65% (35% moisture) for snaplage, and 73% for HM ear corn and corn (27% moisture).On January 15, 2020, estimated inventory was 800 tons of snaplage, 40 tons of HM ear corn and 100 tons of HM corn.Step 4: In the yellow cells enter the feed density as pounds of DM per cubic foot or use the defaults for Snaplage, HM ear corn or HM corn.

If the volume is not known, there are calculators or links to spreadsheets to calculate the volume of a silo, silo bag, bunker or pile.Step 3: In the yellow cells, enter the inventory volume as cubic feet for Snaplage, HM ear corn or HM corn, whichever ones are needed. The equivalent bushels of corn grain at 15.5% moisture are reported in peach below.Step 2: In the yellow cells, enter the tons of Snaplage, HM ear corn or HM corn as fed. Step 1: Enter the dry matter percentage in yellow cells for Snaplage, HM ear corn or HM corn, whichever ones are needed, or use the default values. This tool helps a farmer calculate grain equivalents for snaplage and high moisture corn for including in 2019 production for determining CFAP payments.īegin by downloading the Fractionated Silage to Corn Bushel Calculator spreadsheet.
