Air Pollution and Climate Change
Reducing GHG emissions from soil is crucial for mitigating climate change, promoting sustainable agriculture, protecting ecosystems and biodiversity, ensuring food security, and improving public health. The effectiveness of GHG mitigating strategies may vary depending on local conditions, soil type, and agricultural practices. It is recognized that conventional farming practices may lead to increased GHG emissions compared to more sustainable farming systems. Therefore, the aim of this study is to research the GHG emission variability from conventionally managed soil. The soil flux of N2O, CH4 and CO2 was measured in three conventionally managed monitoring sites in the vegetation periods from 2018 to 2022 using a mobile spectrophotometer Picarro G2508. The average N2O emission at monitoring sites ranges from 4.1 to 6.6 g ha-1day-1, the average CO2 emission ranges from 73.8 to 122.3 kg ha-1day-1, but CH4 assimilation ranges from 1.7 to 5.1 g ha-1day-1. Transitioning to sustainable agricultural practices may help to mitigate the GHG emissions from soil while promoting soil health and long-term sustainability.
