The effect of gypsum amendments on the soil aggregate stability

concentration, exhibited reduced aggregate stability after water treatment, and the applied amendments had a limited stabilising effect. In contrast, the grassland soil from GSC, with higher TOC content, showed greater initial stability and responded more positively to gypsum application, resulting in greater resistance to aggregate breakdown. Overall, the effectiveness of gypsum amendments in enhancing soil structure and reducing susceptibility to water erosion depends on soil properties, particularly organic matter content, particle size distribution, and land use. The obtained results highlight the importance of site-specific management when applying gypsum-based soil amendments.
