NITROUS OXIDE EMISSIONS IN BLACK OAT-CORN FERTILIZED WITH SWINE MANURE AND COMPOST SUPPLEMENTED WITH MINERAL FERTILIZER
Resumo
Manure from pig farming has an agronomic value and it is often used for fertilization. However, as manure has unbalanced amounts of nutrients such as N and C, it contributes to increased emissions of N2O to the atmosphere. This study evaluated N2O emissions in soil with treated with pig slurry (PS) and swine manure compost (SMC). The study was conducted from 2018 to 2019 in an experiment, in southern Brazil. The system was minimal tillage with black oat and corn. The treatments were control, swine manure compost + mineral fertilization (SMC+MF) and pig slurry + mineral fertilization (PS+MF). The measurements of N2O fluxes were carried out throughout the crop cycle with static chambers. Cumulative emission values, as well as crop yield and emission values per ton produced were compared with one another by the LSD test (p
