A comprehensive nutrient management survey was conducted to determine prevailing practices on 34 dairy farms in 2006. Farmers were interviewed at farm by an agronomist and a dairy specialist using a comprehensive survey form. More than 50% of farmers had participated in nutrient management planning and while most famers used soil tests (96%) just over 50% had an analysis of manure with only 22% having done this in the last two years. About 50% broadcast fertilizer prior to seeding corn and almost 70% use starter fertilizer. Forty percent side or topdress nitrogen but less than 30% use the PSNT to determine nitrogen need. More than 75% of the soil samples were taken by fertilizer companies while manure sampling was mostly (76%) done by the farmer. Farmer opinions on manure usage showed application somewhat related to soil test results but most applied without regarded to a N or P restriction. More than 75% of the farmers indicated they had not calibrated the manure spreader. Farmers expressed an interest in learning more about BMPs and manure management but were less interested in knowing more about spreader calibration. Results indicated more education on nutrient management is warranted and that farmers can still make savings on fertilizer purchases if they implement certain proven practices.
