Response of Soil Organic Carbon and Bacterial Community to Amendments in Saline‐Alkali Soils of the Yellow River Delta

ABSTRACT The salt‐alkali barrier and low fertility of coastal saline soil are bottlenecks that restrict the high‐quality development of agriculture, and optimising measures to control salinity and increase carbon content has become an urgent task. The application of gypsum and the retention of straw are increasingly recognised practices aimed at mitigating soil salinization and enhancing soil fertility. However, the combined effects of these practices on soil organic carbon (SOC) sequestration and microbial community remain unclear. A field experiment was performed to analyse the influence of straw (0 and 10 t·ha −1 ) and desulfurization gypsum (0 and 29 t·ha −1 ) on soil chemical properties, aggregate‐related…
