Poultry litter is a great alternative N source for crop production.
However, recent poultry litter management changes, and increased chemical amendment use may impact its N availability.
Thus, research was initiated to evaluate the effect that broiler cake and total cleanout litter amended with chemical additives have on C and N mineralization.
A 35-day incubation study was carried out on a Hartsells fine sandy loam (fine-loamy, siliceous, subactive, thermic Typic Hapludults) soil common to the USA Appalachian Plateau region.
Three poultry litter components (broiler cake, total cleanout, and bedding material) from a broiler house were evaluated and compared to a soil control.
Chemical amendments lime (CaCO3), gypsum (CaSO4), aluminum sulfate (AlSO4), and ferrous sulfate (FeSO4) were added to the poultry litter components to determine their impact on C and N mineralization.
Litter component additions increased soil C mineralization in the order of broiler cake > total cleanout > bedding > soil control.
Although a greater concentration of organic C was observed in the bedding, broiler cake mineralized the most C, which can be attributed to differences in the C : N ratio between treatments.
Chemical amendment in addition to the manured soil also impacted C mineralization, with AlSO4 generally decreasing mineralization.
Nitrogen mineralization was also significantly affected by poultry litter component applications.
Broiler cake addition increased N availability followed by total cleanout compared to soil control, while the bedding resulted in net N immobilization.
Chemical amendments impacted N mineralization primarily in the broiler cake amended soil where all chemical amendments decreased mineralization compared to the no chemical amendment treatment.
This short-term study (35-day incubation) indicates that N availability to crops may be different depending on the poultry litter component used for fertilization and chemical amendment use which could decrease N mineralization.
