The 1979 Dairy Farm Business Summary for Columbia and Dutchess Counties is based on data from 55 farms located in the region. The Cooperative Extension Associations, the Hudson Valley Farm credit Association, and Cornell Univeristy, cooperate in collecting, summarizing and publishing this farm management information annually. The primary purpose of this farm management project is to help the participating farmer acquire a solid base of management information for decision making. This report is in workbook form and the farms are divided into three groups to make comparison easy and more meaningful.
