The closure of aged livestock lagoons and earthen manure storage basins needs to be conducted in a manner that controls potential environmental risk and makes economical use of accumulated nutrients in the biosolids. This event will offer a unique opportunity to hear about and see the step-by-step process for planning and conducting a lagoon closure.
- Describe and demonstrate steps in planning and conducting a lagoon closure using approved practices to mitigate environmental risk.
- Provide attendees with knowledge and resources necessary to plan and conduct a lagoon closure.
