For a number of years the Agricultural Experiment Station has measured and reported the costs and returns in the production of the important agricultural enterprises on Utah farms. These studies have been initiated by a detailed investigation of a sufficient number of farms to reflect the average conditions of the enterprise under study. In each succeeding year sufficient additional field and other data are collected to reflect the changes in prices, costs, and method of production to determine the current costs and returns for that year. Periodically detailed studies have been repeated for each enterprise and the data kept current by the method described above
