This is the first report that seeks to describe the present usage of tower silos in this country, the main implications for management on the farms concerned, and the attitudes of the existing operators. Information was obtained by means of a survey conducted by the author in the latter part of 1968. There is no concern in the present instance with attempting an evaluation of the worthwhileness, on economic or any other grounds, of any particular type of tower silo system. The choice of a normative method of profitability analysis stems from the present lack of sufficient historical real-farm technical data, and the claim by most present operators that their performances to date with towers, due to initial lack of experience and advice, are not representative of what they will be able to achieve in the future.
