Soil salinization amelioration enhances soil organic carbon stock in the Yellow River Delta

Soil salinization is a land degradation process caused by excessive accumulation of soluble salts in the soil, which has become a global ecological and environmental problem. About 7% of the world's land is threatened by salinization. As an important ecological barrier and agricultural production base in China, the Yellow River Delta has suffered from the negative impact of soil salinization. The intensification of soil salinization can damage the structure of soil aggregates, inhibit crop growth, reduce organic carbon input, and further exacerbate land degradation, affecting the sustainable development of agriculture and ecology. Therefore, this study utilized field sample point data collected in January 2022, combined with multi-source remote sensing satellite data, to analyze the spatiotemporal dynamics of soil salinization and soil organic carbon from 2016 to 2022. Here, we share sample point data, research area, and other paper related data.
