Contact: Robert Borg (403) 340-5323 Making cereal crops into silage Many beef producers are moving from grass-legume crops into making silage out of cereal crops. "Basically, the do's and don'ts of making quality silage are the same for both crops," says Bill Grabowsky, beef specialist with Alberta Agriculture, Food and Rural Development, Wetaskiwin. "In order to produce a good product, you need to chop the wet product at the right moisture level, haul it to a storage facility, pack it to remove the trapped air and then cover the product with a protective barrier. Nature should take over from there and in three weeks, the resulting product should be of high ; While this sounds simple, there are some rules to follow. Producers need to chop at the right time and at the right moisture level. Cereal crops, like barley, should be cut at soft dough stage and at a moisture level of 65 per cent. At higher moisture levels, valuable nutrients can leach out through seepage. Cereal crops should be cut at approximately 3/8 of an inch for best results. Too long of a cut can cause packing difficulties as trapped air can't escape. Excessive heat and mould growth can then occur. "Fill the storage facility as quickly as possible," adds Grabowsky. Packing every load is very important as air must be excluded from the chopped crop. The more time it takes to fill, the more time the crop is exposed to the air. The goal in making quality silage is to eliminate the air
