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. The program and demonstration will be held at the Haskell Ag Lab (Concord, NE) on November 1, 2016 form 10 a.m. to 3 p.m. CT. The afternoon will be spent outdoors viewing sludge removal from the lagoon and application to a field. Please dress accordingly. Boots are recommended.
