Manure Nutrient Management Workshops receive high marks
by Tracy S. Petersen, extension communications
The Manure Nutrient Management Workshops offered by Iowa State University extension are reaching their target audience and meeting their educational goals, according to Steve Padgitt, extension sociologist.
"The documentation shows the workshops are reaching a meaningful number and a broad spectrum of producers," said Padgitt, who has conducted follow-up surveys and evaluated the effectiveness of the meetings.
In addition to reaching both large and small producers, the workshops have succeeded in providing active learning and changing practices by livestock producers, he said.
According to survey results, more than 80 percent of those attending the workshops over the past two years raised hogs, while approximately 40 percent of those attending raised cattle.
Seventy percent of those attending the 1997-98 workshops said they developed or revised their manure management plans after the workshop, when surveyed six months afterward.
After attending the workshops, 66 percent made changes in the nutrient credit for manure applied. Forty-eight percent said they changed their manure application rate. Approximately 30 percent of those attending set new, realistic yield goals; changed the location of their manure applications; and developed procedures for keeping field-based records of manure applications.
Those who made changes expected to see financial benefits. Thirty-two percent expected to save $11 to $20 per acre and 24 percent expected a savings of $6 to $10 per acre. More than 70 percent reported decreasing their commercial applications of N, P, and K.
While the changes in operations and practices indicate the success of the workshops, the participants' comments and suggestions do, as well. One producer remarked, "Our operation is 12 sowstwo groups of six sows each farrowing 2 times a year .I was in a workshop with much larger producers who had confinementshoop buildings or fully enclosedthe information covered us all. The binder of information (Ive found an excellent reference) covers all sizes."
The ISUE Manure Nutrient Management Workshops are funded in part by the Leopold Center For Sustainable Agriculture, Iowa State University.
