Producing Maize Silage

In this year's Leaving Certificate Agricultural Science exam, there was a question about the benefits of growing maize silage. Not many Agricultural Science teachers would be familiar with the growth of maize silage and the stages involved (me included). But here is a video form YouTube from an Irish farm making maize silage. It features both photos and short video clips of the main stages in the production of maize silage. Also, some might find this article from Teagasc on maize silage being used as a winter feed for dairy farms interesting and informative. Click here to read the article. Another interesting and easily followed article, from UK Agriculture, on maize silage is here.
