Average nutrient levels in poultry litter. Table 2 shows the available ammonia nitrogen as a function of time until incorporated into the soil. Table 3 lists the percent of available organic nitrogen available by year. Table 4 gives the percent of other nutrients available in the growing season after application. Litter ammonia nitrogen available by days until incorporated.
Unavailable portion is lost to the atmosphere.
Litter organic nitrogen available by year. Minerals and micronutrients available in litter. This publication estimates the amount of litter to apply to meet the soil test recommendations for nitrogen, using a poultry litter of unknown nutrient analysis. The soil test may call for more than 100 pounds of nitrogen per acre to be added to satisfy crop needs. This exceeds the 100 pounds per acre allowed under the conservative management approach.
