The Experimental Farm at Knockaloe can trace its origins to provisions set out in the Agriculture and Rural Industries Act, 1914. In the early 1920s, the Board of Agriculture purchased the site of the old Knockaloe internment camp - which had been vacated by the last internees in Oct 1919 - with monies released by the Noble's Trustees.
The Board proceeded to spend the remainder of the Noble's monies on a clean-up project with a view to readying the site for a return to agricultural usage. A number of arable and pastoral experiments were later based on the site. The Experimental Farm was closed in 2010 by the Department of Environment, Food and Agriculture, a successor of the Board of Agriculture.
