Seasonal variability of soil respiration during maize vegetation

As a source of greenhouse gas emissions, the agricultural sector directly affects the global problem of climate change. A research study was conducted in Western Pannonian sub-region of Croatia to measure soil respiration and its seasonal variability influenced by vegetation presence (maize - Zea mays L.). Soil C-CO2 flux was measured 14 times during the investigated period in a field experiment with 4 different fertilization treatments. Average daily C-CO2 flux was the highest in June 2017 (38.2 kg ha-1 day-1) and the lowest in November 2017 (0.76 kg ha-1 day-1). The results imply that season and vegetation presence has a significant effect on soil respiration rates.
