If a poultry producer rents a manure truck to remove bedding and spread it on the grounds, the poultry producer must keep a record of the carrier`s name, address and telephone number. Requirements such as soil sampling, sampling and waste registration can be addressed by any party (poultry producer, manure transporter or other consultant) involved in the clean-up process. If litter is removed from the producer`s holding, a formal agreement between the poultry producer (litter producer) and the manure transporter carrying out the cleaning and spreading may be required. Drying also reduces ammonia emissions, which reduces odors and fly problems. It works well with multi-level cases as the is on the belts anyway. For some manure transporters, a declaration obligation is required. The requirements are contained in North Carolina Administrative Code Title 15A NCAC 2T. Section 1400. Requirements affect freight forwarders differently depending on the volume of transport.
Manure transporters who land 100 tonnes or less of animal waste per calendar year are not required to submit an annual report. Those who apply more than 100 tonnes of animal waste per calendar year must submit an annual report to DWR by March 1 of each year. Application and reporting forms for slurry trucks can be found at NCDEQ Animal Feeding Operations: Reporting Forms (NCDEQ-DWR 2020). Spreading poultry bedding directly from the barn during cleaning minimizes duplication of handling and maximizes nutritional value. Unfortunately, limited cleaning times, equipment availability, weather conditions, and availability of suitable land often mean that waste needs to be stored for some time before application. Proper storage of waste is essential to maintain its fertilizing value and minimize health risks and pollution. Poultry litter stored in large piles with incorrect moisture content heats up and loses nitrogen and organic matter. This is often considered blackened or ash-gray litter color. In extreme situations, large piles can ignite due to spontaneous combustion. Nutrient loss during storage is also an environmental problem.
Nitrogen and phosphorus can be removed from storage piles in streams or dams or into groundwater. Storage methods vary depending on: Advantages Dry fertilizer has a higher nutritional and financial value and is easier to handle. Pellet manure is retailed at 80p/kg in the UK. The litter also contains trace elements such as copper, zinc, manganese, boron and chloride. Poultry bedding containing dead birds or parts of birds should not be grazed to ensure that dead birds or feathers are not eaten by animals (see warning) and because of the risk of botulism in flocks grazing these pastures. Botulism occurs in animals that ingest the neurotoxin produced by the anaerobic growth of the organism Clostridium botulinum, which can occur in decaying birds. Animals with botulism become paralyzed and usually die. Note: Farm animals can be vaccinated against botulism. As a normal safety precaution, make sure the bedding material does not contain chemicals that could cause a residue problem in farm animals that may graze in dispersed areas. The nutrients in poultry bedding are present in mineral and organic form.
This means that some of the nitrogen, phosphorus and potassium is immediately available to plants, while the rest must react (organically) in the soil to turn into a form available for plant use. Most of the nitrogen in poultry bedding is available shortly after application. About 25% (range 10% to 50%) is in the form of ammonia, which is lost to the atmosphere if it is not grown or released into the soil within days of spread. If nitrogen is washed away by rain or irrigation or incorporated into the soil, it will soon be available for plant growth. Most other nitrogen in poultry litter turns into urea shortly after propagation and now acts in the same way as urea-based fertilizer. Excess nitrogen should not be applied to pastures. It can seep into groundwater or be released into surface water, which can cause a health problem. Excessive nitrogen levels in pastures can also pose a risk of poisoning to grazing animals and susceptible native vegetation.
Approximately 13% (range 6% to 30%) of the phosphorus in poultry litter is in water-soluble form, meaning it is immediately available for plant use. The rest is released slowly as the organic fractions of the litter break down, usually within a year of application. Leaching is usually not a problem because most soils bind phosphorus. Potassium in poultry litter is readily available to plants. Some can be lost due to leaching into the subsoil during excessive rainfall or irrigation. The litter is usually alkaline with a pH around 8; However, compared to lime, it has a weaker neutralizing effect on acidic soils. (The high pH is mainly caused by the ammonia in the litter.) Repeated use of poultry bedding will maintain or slightly increase the pH of the soil. On highly acidic soils, the mixture of lime in the soil improves pasture growth. The moisture content of bedding is variable, which is one of the reasons why it is sold by volume (cubic meters) rather than weight (tons). The moisture content affects the amount of dust and overlap required during application. It is also important when calculating the rate of nutrients applied to a paddock. Poultry bedding consists mainly of organic matter.
Organic matter helps retain moisture, improves soil structure, promotes organisms such as earthworms, and retains and provides nutrients. Any increase in organic matter usually improves your soil. The amount and timing of land application – the most common way of treating manure – is already regulated by nitrate vulnerable zone (NVZ) regulations and environmental permits, and these controls are further refined by the 2018 Defra water cultivation rules and this year`s government strategy. However, not all nutrients in the litter are available in the year of use. Assuming 70% of the nitrogen and 80% of the phosphorus and K are available, the corresponding fertilizer would cost $54.21. If these assumptions are correct, farmers could afford to pay up to $20/m3 for poultry bedding at the prices shown in this example. These calculations could be repeated with different fertilizers and prices. When using commercial fertilizers, nutrient availability, losses and application costs can also be taken into account.
