Measurement of carbon dioxide and nitrogen oxide emissions from triticale field in Croatia

The three greenhouse gases (GHGs) associated with agriculture include carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4). While the CO2 represents the major GHG issue for the total economy, N2O, even though is a small part of the overall GHG issue, becomes the most important for agriculture considering soil management and fertilizer use. This research, conducted in a conventional agroecosystem under triticale vegetation in Popovaca, was based on measurement of CO2 and NO2 emissions using a static chambers for CO2 and method with passive samplers and static chambers for NO2. The aim of this study was to determine the amount of C-CO2 emitted from the soil into the atmosphere, depending on different amounts of nitrogen fertilizer (0-300 kg N/ha) during the vegetation. Also, the aim was to determine the suitability of the selected method for N-NO2 concentration measurement and to determine the potential impact of mineral fertilization on the N-NO2 emission (0 and 300 kg N/ha). Mean annual values of C-CO2 emissions ranged from 10.4 kg/ha×day on the treatment X (black fallow) up to 26.1 kg/ha×day on the control treatment (I) and treatment with 250 kg N/ha (VI). A weak correlation between the amount of nitrogen (0-300 kg/ha) and the emission of C-CO2 was determined (r = 0.26). The used method was suitable for N-NO2 concentration. Measured daily values of N-NO2 emission ranged from 1.66 to 7.18 mg/ha per day, depending on phenophase and treatment. Statistically significant differences in N-NO2 emission between two monitored treatments (300 kg N and 0 kg N) were not observed.
