Abstract

Abstract – Swine production is fundamental in Brazil and it seeks suitable use for swine slurry (SS) in agricultural areas. The objective of this study was to evaluate the effects of SS and urea application, treated or not with nitrification inhibitor (DCD) and the way of fertilizer distribution, associated or not with crop residues, on CO2 emissions in a controlled environment. The soil used in this study was a Humic Dystrudept soil and daily and accumulated CO2 emissions were measured. Daily CO2 emissions increased with SS use. There was no difference considering the way the fertilizers were applied. The use of straw increased CO2 emissions. Accumulated CO2 emissions were higher under use of straw associated with SS.
