Conteúdo: |
The use of cover crops and poultry manure (PM) is an alternative to reduce
the use of synthetic inputs and can contribute to the nutrient cycling in onions (Allium
cepa L.) grown under a no-tillage system. However, this management practice may
contribute to an increase in N2O emissions to the atmosphere. The aims of this study
were to evaluate the immediate effect on N2O emissions of adding PM onto cover crop
residues and to verify the effect of different no-tillage systems on N2O emissions. Two
studies (laboratory and feld) were conducted with the addition of oilseed radish (OR),
black oat (BO), and weed (WD) residues with and without PM under a no-tillage (NT)
system. Emission of N2O (kg ha-1) was influenced by the different residue-management
systems and was higher in treatments with OR residues (2.96 ± 0.67 kg ha-1 for OR and
5.28 ± 1.04 kg ha-1 for OR + PM). The other treatments behaved similarly with emissions
of approximately 1.91 ± 0.17 kg ha-1 of N-N2O. The highest N2O emissions in the feld study
were found within the frst 15 days and represented 50.3 % of the average emissions.
Poultry manure showed high emissions when the cover crop was OR, but not when it
was BO and WD. |
