Soil fluxes of carbon dioxide in winter wheat (Triticum aestivum L.) agroecosystem

The increasing release of greenhouse gasses from soil to the atmosphere is an important contributor to global climate change. A research study was conducted to compare data of carbon dioxide emission from soil during winter wheat vegetation in 2012 and 2016. Also, the relationships between soil CO2 emissions, agro-ecological factors, and N fertilization were determined. The soil CO2 emissions were higher in 2012 compared to 2016 due to the higher temperature during summer period. The lower precipitation in 2012 did not reduce the soil respiration. Statistical analyses determined that the same N fertilization treatments significantly differed between studied years in I, II, IV, VI treatment. The observed differences among treatments in soil CO2 emissions show that the addition of N fertilizers increased soil respiration.
