Determination of Biological Nitrogen Fixation Induced N2O Emission from Arable Soil by Using a Closed Chamber
Technique
Figure 1
Temporal dynamics of N2O flux (μg kg−1 hr−1), soil pH, DOC (mg L−1), and -N (mg kg−1) of IS treatment. Different lower case letters indicate a statistically significant difference at α = 0.05. R2: full flowering; R3: beginning pod; R4: full pod; R5: beginning seed; R6: full seed; R7: beginning of maturity; R8: full maturity. Means of 3 replicates with standard error.
