Long-Term Cotton Straw Returning May Increase Soil Secondary Salinization Risk in Some Xinjiang Cotton Fields: Evidence of Threshold-like Responses and Spatial Heterogeneity

Background: Cotton straw returning (CSR) is widely implemented in Xinjiang to achieve in situ residue utilization and ameliorate saline–alkali soils. However, its long-term efficacy in improving soil fertility without inducing secondary salinization remains poorly understood. Methods: This study eva...
