Assessment evaluates greenhouse gas emissions in onion production, indicating soil management impacts.

Key Points

This research aims to assess the impact of different agricultural management systems on soil properties and greenhouse gas emissions in onion production.
Evaluated three soil management systems in a long-term agroecological field experiment.
Monitored greenhouse gas emissions (N2O, CH4, CO2) during one onion growing season.
Assessed soil physical and chemical properties, including carbon and nitrogen stocks, soil aggregation, porosity, and bulk density.
The no-till vegetable (NTV) system improved soil quality and increased onion yield compared to conventional tillage (CT) and no-till (NT).
NTV system showed higher cumulative N2O emissions, indicating a trade-off between emissions and long-term soil benefits.
All systems were effective methane sinks, with NTV showing greater CH4 uptake.
