Abstract

Quantification of CO2 emissions was tested in the years 2016 - 2018 on gleyic fluvisol in Milhostov at the grain maize. Maize was grown in two soil protection technologies (reduced tillage, direct sowing without tillage, resp. no-tillage), which were compared with conventional tillage with ploughing. The field experiment was established as a rotation of four crops: grain maize, spring barley, soybeans, winter wheat. Soil CO2 emissions were measured at each tillage. Every year, in the monitored years higher CO2 emissions were found in conventional tillage (average 0.166 g m-2 h -1 ) and lower at reduced tillage (average 0.157 g m-2 h -1 – reduced tillage. resp. average 0.153 g m-2 h -1 direct sowing). From the point of view of the year a higher emission of carbon dioxide from the soil was found in 2016 (average 0.184 g m-2 h -1 ), lower in 2017 (average 0.152 g m-2 h -1 ) and the lowest in 2018 (average 0.142 g m-2 h -1 ). The differences in CO2 emissions found between tillage and reduced tillage and direct sowing were statistically insignificant.
