Greenhouse Gas (CO2, CH4, N2O) Flux Associated with Agricultural Fields with Residual Poultry Litter Applied as Banded and Surface Applied Treatments.

Tillage and fertilization practices used in row crop production are thought to alter greenhouse gas emissions from soil. One fertilization practice that can have long lasting impacts in greenhouse gas emissions is poultry litter.  Poultry litter is increasingly being used as a source of fertilizer in the Sand Mountain region of Alabama due to the predominance of poultry producers in this area.  Thus, a field experiment was conducted at the Sand Mountain Research Station located in the Appalachian Plateau region of Northeast Alabama on a Hartsells fine sandy loam. Measurements of CO₂, CH₄, and N₂O emissions were evaluated using GRACEnet protocols to assess the effects of different tillage (convention vs. no-till) and fertilizer application (banding vs. surface application) practices in a corn cropping system. Thus, the results of this study will show the residual  impacts of poultry litter application (150 N  kg ha -1)  on greenhouse gas emissions approximately one year after application.
