Freeze-thaw perturbation decreases priming of soil organic carbon mineralization induced by straw return in croplands
Straw addition is a widely used agricultural practice to maintain soil fertility. However, its effects on soil organic carbon (SOC) and nutrient cycling are complex, with outcomes ranging from inhibition to stimulation of SOC mineralization via the priming effect. Freeze-thaw cycles are common disturbances in agroecosystems of high-altitude regions that are predicted to increase in frequency and s
