Optimizing Soil Health and Remediation Performance in Saline-Sodic Soils via the Combined Effects of Chemical and Organic Treatments

Yawei Luo

We investigated the individual and combined effects of gypsum, elemental sulfur, vermicompost, biochar and microbial inoculation on soil health improvement in saline-sodium calcareous soils. is degenerating. We have developed linear and non-linear quantitative soil health frameworks to evaluate the effectiveness of remedial measures. Combined organic and chemical treatments; gypsum + vermicompost and elemental sulfur + vermicompost with increases of 134% (0.29 vs 0.68) and 116% (0.29 vs 0.62) in the nonlinear index, significantly increased the effectiveness of the modifications compared with the control. The increase in the overall health index of the soil ranged from 12 to 134%. Microbial inoculation further improves the treatment's impact on soil health. The soil health properties included in the indices explained 29–87% of the variance in wheat growth. The results provide insight into cost-effective and environmentally sustainable methods to rehabilitate degraded saline-sodium soils. In addition, soil health indicators are introduced that provide a quantitative assessment of soil treatment strategies.
