Management styles for poultry operations, such as cleaning buildings on a certain schedule, dictate different techniques than commercial fertilizer that can be ordered and spread. If a laboratory analysis is not available, use average values of manure nutrients in similar waste management systems. Table 1 lists values for poultry litter. Average nutrient levels in turkey and broiler litter. Manure ammonia N loss by days until incorporated into the soil.
Unavailable portion is lost to the atmosphere.
Table 4 gives the percent of various nutrients available in the growing season after application. Table 5 provides a basis for estimating the expected nitrogen release from soil organic matter for major annual crops instead of a soil test. Table 6 lists N credits for crops following legumes. Manure organic nitrogen available by year. Minerals and micronutrients available in manure.
