The processing goals are to improve manure characteristics (density, nutrient availability, nutrient profile, and energy content) to make its utilization easier or to create value-added products from manure. The heating and ventilation systems in a poultry house must be continuously monitored to keep the moisture content of the litter controlled so that the litter remains friable (easily broken up or crumbly). Uric acid and organic nitrogen (N) in the bird excreta and spilled feed are converted to ammonium (NH4+) by the microbes in the litter. If you are unsure whether the lab has listed available nitrogen, contact your county Cooperative Extension center for assistance. Nitrogen recommendations for various crops are determined using the soil type and crop rotation. Be aware that other laboratories may list total nitrogen and require adjustment using the availability coefficient. Also keep in mind that in fields with long-term repeated manure application, elements such as copper or zinc may accumulate and reach very high levels, which can cause severe plant toxicity. Poultry litter has traditionally been disposed of by spreading it on the land as fertiliser or by sending it to landfill. Receive Email Notifications for New Publications. In a well-managed broiler house, litter moisture normally averages between 25 and 35 percent. Therefore, the producer would need 39.2 acres for a year’s worth of litter (360 tons of litter produced annually, To compare the value of manure to commercial fertilizer, convert total manure nutrients to available nutrients by using the availability coefficients. The caked portion of the litter is very high in moisture and nitrogen and should be removed from the house to reduce ammonia generation and provide optimal air quality for chicks during the brooding period. The choice of processing method depends on resources available on the farm (such as space, labor, capital, equipment, and fields to utilize the manure) and also market demand for these products. When the zinc or copper indices hit 2000, start considering alternative application areas; when the index exceeds 3000, you will need to discontinue applying manure or any other amendments containing zinc or copper. Other qualified private laboratories can also perform the analysis (fees vary). In agriculture, poultry litter or broiler litter is a mixture of poultry excreta, spilled feed, feathers, and material used as bedding in poultry operations. In areas with high levels of phosphorus as determined by a soil … Consider the following example: analysis of the available nitrogen, phosphorus (P2O5), and potassium (K2O) content in a broiler litter sample that will be incorporated shows that it contains 43 pounds of nitrogen per ton, 62 pounds of phosphate per ton, and 37 pounds of potash per ton. Apply manure only to an actively growing crop—within 30 days of planting or within 30 days of breaking dormancy. Nitrogen takes several forms in poultry litters, each of which can be lost when subjected to different environmental conditions or management practices. The material should also have a useful purpose once it has been used as a bedding material.

N.C. poultry integrators (DeLaune et al., Poultry litter is a mixture of . To avoid problems, use a current waste analysis and soil test report to monitor nutrient levels and make application decisions. Regionally, other materials have been the bedding material of choice due to regional cost and availability, such as rice hulls in the lower Mississippi River poultry production areas of Arkansas and Mississippi.[1]. In 1980, FDA reversed this policy and passed regulation of litter to the states. Poultry litter is a rich fertilizer with a great number of nutrients essential for plant growth and has been used as organic fertilizer for centuries. The FDA decided at this point that a litter ban was unnecessary in part based on comments by the North American Rendering Industry. Because poultry litter can contain recycled cattle proteins as either spilled feed or feed that has passed through the avian gut, the FDA was concerned that feeding litter would be a pathway for spreading mad cow disease. Therefore, there is no need to make this adjustment if your sample has been analyzed by NCDA&CS. These processes use high temperature and controlled air levels to generate thermal energy (heat) or gaseous fuels (syngas), depending on the process conditions. This publication printed on: Nov. 29, 2020, Skip to Nutrient Composition and Sampling Procedure, The nutrient composition of poultry litter varies, depending on the type and life stage of bird, feed ration, proportion of bedding to droppings, manure handling system, and type of litter (cake versus whole house). However, ammonia loss from the litter reduces its fertilizer value, and venting ammonia into the environment can cause health and environmental problems.[4]. In order for a material to be used as litter it must be of medium size, have good absorption capacity without hardening, easily release … Depending on poultry manure composition, adding a carbon-rich material (for example, straw or wood chips) might be necessary to ensure favorable carbon-to-nitrogen (C/N) ratio, between 20 and 30, to initiate the process. A lack of uniformity leads to nutrient imbalances within the field, which can result in reduced yields or quality. Watery droppings caused by nutrition and/or infectious agents can also be a cause of excessive moisture in poultry litter. How many acres of fescue would be needed for the entire year’s waste? For every 1,000 broilers, 7.2 tons of litter is produced annually from whole-house cleanout. It describes the differences in composition and plant availability based on factors affecting the … This includes litter from meat chickens (broilers), egg laying chickens (layers) kept under barn conditions, turkeys, ducks and quails. In most cases, nitrogen determines the application rate. One common practice is windrow composting. On sandy-textured soils, apply manures at low rates throughout the growing season, wherever possible, to reduce nitrogen leaching. Re-spreading the stacked litter and allowing it to dry would be expected to decrease ammonia and extend litter life. While these averages can be used for initial nutrient management planning, actual waste analyses should determine the application rates. and animal excreta . When running the PLAT analysis, conservation practices implemented on your farm will affect the calculated risk of phosphorus loss to the environment. Place the subsamples in a clean plastic bucket, mix thoroughly, and transfer approximately 1 pint of the mixture to a sample container. Attorney General and Arkansas . In most cases, nitrogen determines the application rate. Using total nutrient value will generally result in overestimating the dollar value of the manure. Poultry litter is the mix of bedding material, manure and feathers that result from intensive poultry production. Cooperative Extension prohibits discrimination and harassment regardless of age, color, disability, family and marital status, gender identity, national origin, political beliefs, race, religion, sex (including pregnancy), sexual orientation and veteran status. Poultry litter (or poultry manure) is an excellent source of nutrients that can be incorporated into many cropping systems in North Carolina. Poultry litter can support the growth of Salmonella and the production of aflatoxin, so care needs to be observed to assure that the poultry litter has been properly processed. This translates to an average of about 0.7 ounce per day per bird, varying considerably over the life of the bird. NC State Extension’s SoilFacts publication Deep Soil Sampling for Nutrient Management describes protocols for deep soil sampling.
