The Journal is published twice yearly by Teagasc (Agriculture and Food Development Authority), Dublin. Papers on any aspect of agricultural research, including plant and animal sciences, food science, soils, engineering, buildings, economics and sociology will be considered for publication. Notes or Communications to the Editor will also be considered. Papers published or offered for publication elsewhere will not be accepted, but the publication of an abstract does not preclude publication of the full paper in this Journal. Opinions expressed in papers are those of the contributors.
