The American Society of Agricultural and Biological Engineers (ASABE) has revised its standard on manure storage safety.

The revised standard, ASAE EP470.1, Manure Storage Safety, reflects field research on worker safety and proper removal of waste from confined manure storage structures. Additional changes include information on confined space entry with references to a relatively new ASABE safety standard, ANSI/ASABE S607, Ventilating Manure Storages to Reduce Entry Risk.

The eXtension Livestock and Poultry Environmental Learning Center is presenting a webcast on Nov. 18 on the topic, "Economics of Using and Transporting Manure." Transporting manure nutrients and using manure in vulnerable watersheds, such as the Chesapeake Bay and the Illinois River basin, has become an issue grabbing increased national attention. Researchers have studied sustainable use of manure in these watersheds and alternative storage systems that can make transport of manure such as poultry litter more economically feasible.

The webcast will delve into the economical implications of moving nutrients outside of these watersheds. The webcast will be held at 1:30 p.m. (central). On the day of the webcast, go to www.extension.org/pages/ to download the PowerPoint presentations and connect to the virtual meeting room.
