Trench Silo Demonstration v Wintry winds blew, and a light covering of snow failed to curtail |the crowds at Friday’s Lancaster County trench silo demonstrations on the farms of John M. Groff, R 1 Bareville, and the Harry Grif fith Farm operated by Robert C. Groff just north of Quarryville on R 3. Looking over Trench Silo Cuts Feeding Costs in Lancaster County Dairy Enterprise By ERNEST J. NEILL Editor, Lancaster Farming Seeking cheaper milk at the production level, Robert C. Groff has reduced hay purchases through use of a trench silo. Mr. Groff, who farms the Harry Griffith place just north of QuarryviUe, was one of two Lancaster County hosts in a trench silo demonstration Fri day. Explaining procedures and construction were M. M. Smith, Lancaster County agricultural agent, and John Walker, exten sion agricultural engineer from Pennsylvania State University. John M.

Throughout the country, trench and bunker-type silos have been constructed to pro wide cheaper winter feed, and. in emergencies, to v salvage drought burned crops. Locally, however, the silos of this type have been used to get a maximum amount of feed from a minimum acre age. At Bob Groff’s, the latter is the case. He operates a farm of 148 acres, is now milking 13 head of Holstems that pro* duce 320 gallons of milk daily) and feeds 50 head an average of 60 lbs of- silage a day. Markets bi Philadelphia Bob is justly proud of the pro gress he is making since moving into Southern Lancaster County from the Stevens’ neighborhood. Today he is selling Grade A milk to Abbott Dairies, Philadelphia, with the primary supply of wint er feed coming from nine acres of land- ) One hundred and ten loads almost 200 tons of soybeans and sorghum, or soybeans and sudan, went into the silo Using this combination, no preseiva tives were necessary. sssssss ESS3SEK3ZEEB workmen to assure Its meeting e» act John Deere quality standards.

'St *'' 4k\ Mr. Griffith pointed out that dirt mounds around the trench silo which runs north and south, opening to the south, divert rain water, preventing erosion and spoilage Dimensions of the trench silo are 78 by eight feet at the bottom, 78 by 14 at the top. When filled 10 feet high, and well crowned, it holds an esti mated 180 to 200 tons. So far, in the first year, success has been proved, with only two or three inches of spoilage. Sixteen ton of sand, 24 tons of stone, ans 114 bags of cement went into construction of this trench silo, at a total cost of $753 50- Breakdown of Costs Some dynamite was necessary to break up rock formations on the slope where construction was made Digging cost $l6O, blade work—sB2 50 and labor approxi mately $270, figured at $1 per hour. The first side was erected in one day, the second side was erected on a less steady basis, but was completed in 2% days by three men. “You should figure digging costs at approximately $1 per ton of capacity,” Mr. Walker ex plained, showing the Gnffith- Groff contruction figures very closely to customary estimates. The Penn State engineer added that trench silos can be con structed over a period of years, and used during that time The first year they may be used without concrete, perhaps even into the second year, to spread the costs over a longer time “It will take about one-third of a yard of concrete per ton of capacity, and when figured at $6 per ton, concrete should cost about $600,” he added Trench Silo Labor Saver The trench silo is a labor sav er, Mr Smith and Mr Walker told the group It is easier to till, easier to use Costs are low. It may be built quickly, and (there is less danger involved than in a tower silo. Three men filled the silo in the southern end of the county in four days, using a field chop per There as more spoilage in a trench silo than in an upright, but this loss is easily offset by cost. “You can’t dig trench silos every where due to the water table being too shallow,” Mr. Walker warned, “but in that c<N£ you can use a bunker-type silo.” “A v trench silo is ideal when constructed on a bank, and there should be an eight-foot fall in each 80 feet to assure proper drainage,” Mr. Walker advised. At the same time, trench silos should not be constructed too near dug wells, or water may be blackened and contaminated, j Lancaster Farming, Friday, February 24, 1956 or too near the residence, where odors may be offensive. Con struction close to the barn or feeding area is advised, allowing room for juices to seep away, and to save labor. Any Hay Mixture Sides should slope back two feet at the top in an eight-foot wall. Slanted sides ease packing, and will give less spoilage than vertical walls- Bob uses a rubber-tired trac tor to pack his silage, as weight is more concentrated on tires than on the broad footage of a track tractor. Mr. Smith explained other fea tures of a trench hilo especially crops that can be used. “Any hay mixture is good; soybeans sorghum or soybeans and Sudan offer some of the best tonnage, and no preservative is neces sary,” he told- If preservatives are necessary, any cereal crop chopped or ground can be used. Grasses and •legumes - need preservatives. Another good combination plant ing for Lancaster County is Canadian field peas and spring oats, using a bushel of inoculated peas to a bushel of oats to seed one acre. “Make sure you combine crops that mature simultaneously,” Mr Smith warned. In the peas oats combination, seeding should be done in March, with fertilizer drilled separately. Harvest when small peas form, when oats head out. Be sure to use preserva tives,” he told. “It takes high quality’ hay to make high quality silage,” Mr. Smith added. Com May Be Added Corn may be added to serve as both a preservative and to in crease pala'tability crushed or ground. Preservatives must be mixed thoroughly and it would be advantageous to mix them at the field chopper as the ground material goes into the blower. Crops destined for silage need moisture,‘and those over mature FROM HERE %'mm| PENNSYLVANIA COMMUNITY TELEPHONE COMPANY -DALLAS, PA. QUABBYVILLE. PA. A Subsidhrv of the Commonwealth Telephone Co. are of little value. Grass is best when just heading. Alfalla serves best just before it shoots a head, or m 10 to 20 per cent blossom. Clover in onenthird blos som is also good, and alsike in full bloom may be used. By cutting at this period, it is possible to save more of the feed nutrients than m any other form of feed harvest. “Put good stuff an your trench silo. Cut grass at the proper state of maturity, when it’s green and juicy. Use preservatives,” Mr. Smith admonished. Seal Top Carefully Pack silage well, the group was told, especially along the sides, which aie more vulnerable to seepage. The top must be care fully covered, and the best seal is tarpaper and dirt or sawdust. Three inches of ground limestone may be spread evenly on top, and after a rain or two will form a weather-proof crust. Feeding is ordinarily from the front end of the silo, using a tractor scoop or loader. Mr. Smith advises against self feeding dairy stock. For beef cattle and dry cows, yes, but hand feeding is recommended in. the case of dairy stock. Mr. Walker showed a scale model of an ideal trench silo, as well as models of feeding gates, both movable wooden gate type, and gate suspended from chains on a bar crossing the top of the trench silo Summing up the advantages of a trench silo, Mr. Smith told, “You can get the most feed value by making grains into silage. You use all feed nutrients. You cut the need for hay but some dry material, 5 to 10 pounds daily, is still needed” Around 40 attended the Bare ville meeting too. It looks like the government’s latest raising of interest rates checked the boom Now every one is watching for the next move. TO HERE 5
