Dry bulk animal nutrient producers and distributors need better understanding of nutrient management and planning
A field day was held in Clarion, Iowa in 2005 to address dry bulk animal nutrient management and planning. This field day was developed in collaboration with USDA Natural Resources Conservation Service (Iowa NRCS), IMMAG, Iowa Department of Natural Resources (Iowa DNR), and Iowa Department of Agriculture and Land Stewardship (IDALS). A total of 101 participants from Iowa, Illinois, and Minnesota were present at the field day. About one-half of participants were dry bulk animal nutrient producers/distributors, corn/soybean producers, and the other-half of participants were consultants, service providers, agency staff, and industry representatives. At this field day, Iowa DNR, Iowa NRCS and ISU Extension faculty and staff provided training on water quality and nutrient management using a rainfall simulator, sampling dry bulk animal nutrients, and dry nutrient application using spreaders to verify uniformity and distribution. Participants were also educated on Iowa DNR regulatory requirements, NRCS technical assistance, and requirements for sales of dry bulk animal nutrients under IDALS.
Forty-one percent of the participants completing evaluations reported that they plan to sample dry bulk animal nutrients because of the training received at the field day. Fifty-three percent indicated that they better understood water quality issues due the rainfall simulation conducted at the field day and they plan to incorporate dry bulk nutrients once applied to crop land. Forty-seven percent of the participants indicated that they plan to calibrate their spreaders for uniform application as a result of todays training. Eighty-two percent of the participants reported information provided at the workshop as helpful towards better management of dry bulk animal nutrients. Participants completing the evaluations represented an average farm size of 3,300 acres. Economic benefit gained from the field day was reported as $0.32 per acre represented.
