Cultivar-dependent differences in soybean N2O emissions under wet, nitrogen-limited conditions: an eight-month pot experiment
This eight-month pot experiment reveals that while soybean cultivar differences in N2O emissions were negligible during the growth period, they emerged post-harvest under wet, nitrogen-limited conditions, with one high-yield cultivar showing notably lower emissions, and further demonstrated that plant physiological activity, particularly transpiration, significantly drives short-term emission fluctuations.
