The Mechanisms of Soil Conditioner and Switchgrass in Improving Saline-Alkali Soil: A Field Study in a Semi-Arid Area.

ABSTRACT: Chemical and plant-based strategies have become increasingly critical for the remediation of saline-alkali soils. However, the underlying mechanisms driving improvements in soil quality and ecological functionality remain insufficiently understood. In this study, we adopted a synergistic remediation approach that integrated multiple switchgrass (Panicum virgatum L.) cultivars with a coal-based soil amendment to enhance saline-alkali land. A field experiment was conducted using five switchgrass varieties (YM-1, YM-2, YM-3, YM-4, and YM-5), each receiving a uniform application of the coal-based soil conditioner at 10 t ha^-1. A traditional control group was not included in this study, as the experimental design focused on direct comparisons between varieties. Our results sho
