New Jersey Administrative Code › Title 2 - AGRICULTURE › Chapter 76 - STATE AGRICULTURE DEVELOPMENT COMMITTEE › Subchapter 2A - AGRICULTURAL MANAGEMENT PRACTICES: GENERALLY ACCEPTED OPERATIONS AND PRACTICES › Section 2:76-2A.3 - Poultry manure agricultural management practice

Current through Register Vol. 56, No. 14, July 15, 2024
(a) The poultry manure agricultural management practice applies to agricultural operations, which store poultry manure prior to land application and land apply poultry manure as part of crop production practices. Poultry manure is collected and stored in a variety of ways, depending on the need of the producer. The methods used to collect, handle and store the manure greatly affect its quality. Manure often has to be stored before it is land applied. Proper storage is essential for manure to maintain its value as a nutrient resource and to prevent it from polluting surface or groundwater. The important points to consider when storing poultry manure are to keep it covered so rainfall will not create runoff from the storage area and to stack the manure no more than five to six feet deep to prevent overheating and burning.
(b) Poultry manure should not be stored outside unless it is covered by some type of waterproof sheeting and water is diverted away from the stack. The manure stack should be located on high ground and away from drainage ways and sources of surface water. Covered stockpiles should be considered for short-term storage only. If manure will be stored in this manner for more than one month, place an impervious pad under the stack.
1. Stockpiles of manure can be protected by covering with plastic sheeting, which is anchored with earth or other suitable weighted materials. Anchor the edges by laying the sheeting edge across a small trench approximately 12 inches deep and backfilling with soil. Lay suitable weighted materials over the top of the plastic on the pile. Heavy gauge (six mil) plastic can last one or two seasons. Lighter gauge plastic is not recommended.
2. The liner consisting of a minimum of a six mil plastic is laid on the soil surface on top of which the stockpile is formed. If the soil is loose, compact it before laying out the plastic. Apply a 12-inch layer of manure over the majority of the plastic before forming the pile to minimize the possibility of tearing by the equipment tires. Fold the edges of the liner one to two feet up the sides of the pile and anchor in the manure. Apply the surface cover as described for a covered stockpile. The ground liner will be torn during unloading of the pile and new plastic will be required each year.
3. If a permanent location for manure storage is desired, a concrete slab can be constructed on which to place a covered stockpile. The concrete should be at least six inches thick, reinforced with wire mesh and placed on six inches of compact gravel. To prevent concrete failure, thicken the perimeter of the concrete to form a footer where traffic enters and exits. Construct the stockpile as described for a covered stockpile, as set forth in (b)1 above. Anchor the cover sheet edges with wood poles, concrete blocks or other heavy objects on the concrete slab.
4. Bunkers are permanent aboveground concrete slabs with two parallel walls of concrete identical to those used for storing silage on livestock farms. A bunker allows deeper piling and compaction of manure to reduce the total area required for the manure storage. An end wall can be constructed to slightly increase the storage capacity. However, loading the structure is more easily accomplished without an end wall. A cover of plastic sheeting can be attached to the walls with batten strips and anchored with a suitable weighted material. A more permanent cover of fiberglass reinforced fabric with edge anchorage eyelets similar to that used for truck covers may be utilized.
5. Concrete slabs, bunkers or other structures with permanent roofs may be constructed to eliminate the need for plastic covers. The roof structure must be a clear span supported by the outside walls or perimeter posts. Roof structures must be of sufficient height to allow manure piling. Compaction loading will be difficult under a roof. Roofs 12 feet or higher will require wall panels to protect the stored manure from excessive blowing rain.
