Follow iowamanure on TwitterThis newsletter is devoted to resources available on the IMMAG web page. Some of the resources will help you meet regulatory compliance such as record-keeping and other resources will provide a basis to achieving good manure management stewardship. Stewardship is the part we should all do every day to get the most out of our manure nutrients for crop production while protecting our natural resources. For this month, resources will focus on open feedlots. For June, the resource list will focus on confinement feeding operations and SAFOs.

General. Information in these publications is applicable to all livestock operations as well as cropping operations that use manure as a nutrient source.

Large Open Feedlots. Generally speaking, in Iowa, these are beef and dairy open lots that have over 1,000 beef cattle or over 700 head of dairy. State and federal law requires these operations to maintain certain records. The use of forms 1-11 (form 6 no longer exists) is optional, but those forms do meet the recordkeeping requirements. You may opt to use your own recordkeeping format. Form 1-11 were created by Iowa State University Extension and Outreach. The two DNR forms are required for the quarterly and annual reports to the Iowa DNR.
Form 1  Solid Manure Handling/Application Record
Form 2 Weekly Manure Storage Inspection and Maintenance Log
Form 3  Pumping Activity, Storage Volume, and Level Record
Form 4  Measured Manure Analysis
Form 5 Manure Spreader Calibration and Maintenance Log
Form 7  Off-site Manure Transfer Log
Form 8  Animal Inventory and Mortality
Form 9  Livestock Waste Discharge Notification

The IMMAG Events page is a compilation of manure management related events. Please check the events page often for new listings.

Iowa State University Extension is hosting two series of workshops to assist livestock producers in understanding the on-going DNR inspections. The series, Staying on Top of Manure, has 3 meeting dates and the series, Preparing for Environmental Audits, is scheduled for 7 different locations. Please visit the IMMAG web page for dates and locations and additional details.

Road-trip anyone? Don’t forget the 2014 Manure Expo Valuing Manure and the Environment, will be held near Springfield, MO on July 8 and 9. This is a great event to see manure equipment in action, listen to current research on manure issues and network with industry representatives.
