The effects of tillage practices on the soil organic carbon content and the CO2 distribution in the maize canopy in saline‒alkali cropland areas

Context Saline‒alkali cropland exhibits high soil salinity and low carbon content levels, leading to deterioration in soil physical and chemical properties. Aims This study aimed to test the effects of tillage methods on soil organic carbon (SOC) functional groups and the CO2 distribution in the maize canopy. Methods The experimental design used two tillage methods: subsoiling (ST) and rotary tillage (RT). The physical and chemical properties of soil, as well as the CO2 concentration in the cano
