This work evaluated the impact of the two main soil tillage systems (disk harrow followed by offset disk harrow, and chisel plow) with different adjustments on the immediate soil CO2 emissions. Results showed the highest emissions after conventional tillage, disk harrow followed by offset disk harrow, of 260.7 grams of CO2 m-2 during the period of 14 days after tillage. On the other hand, the smallest emissions were registered after chisel plow, 82.3 grams of CO2 m-2, when not conjugated to the clod breaker. The factors temperature and moisture were not related to the CO2 flux from soil; however, time was important for predicting emissions after tillage.Downloads
