1. Changing from a conventional to alternatively managed maize/
soybean rotation ecosystem (strip tillage with spring cover crop)
caused RE to increase by 222.7 g C m2.
Decomposition of the rye cover crop was the main factor that increased cumulative RE
and RS in the experimental treatment.
2. Cumulative N2O losses, expressed in CO2–C equivalents, were 12.8 g C m2higher in the conventional treatment during one of the two study years. N fertilization was the main factor that increased N2O losses in both treatments and N fertilizer type likely had a large influence on the differences between the two treatments.
