The Ohio Extension Service conducted "in-depth" schools on Dairy Genetics and Reproduction, Beef Cattle, Capital Management, and Fertilizer and Lime at area centers in Wooster, Defiance and Fremont, Washington Court House, and McConnellsville. Two thirds of the instructional staff were area agents; others were specialists, resident staff, research personnel, and industry representatives. The major audience were full time commercial farmers, 90% of whom were high school graduates, 1/3 having some college; 3/4 had recently been involved in other extension activities. Most had had contact with extension agents during the three previous years, 10% having office or telephone contact with area agents. The school directed toward fertilizer dealers drew both large and small dealers, most of whom had learned about the school from extension agents. Participants made significant gains in subject matter knowledge and planned to try new ideas, particularly cash flow analysis. The programs were considered a success. (se)
