Special Issue Information

Dear Colleagues,

Soil fertility and carbon management are fundamental to achieving sustainable agricultural productivity, particularly in cereal-based systems that underpin global food security. This Special Issue of Plants aims to explore strategies for optimizing soil fertility and enhancing carbon sequestration in agricultural soils, highlighting cutting-edge research on nutrient management, soil organic matter dynamics, and sustainable practices to improve soil health and mitigate climate change impacts. By addressing key challenges such as soil degradation, greenhouse gas emissions, and nutrient imbalances, this Issue seeks to provide actionable insights for researchers, practitioners, and policymakers working toward resilient agroecosystems.

Topics of interest include but are not limited to:

  • Soil amendments and organic matter management;
  • Carbon sequestration potential in cereal-based systems;
  • Precision agriculture for nutrient optimization;
  • Sustainable crop rotations and intercropping;
  • Impact of soil microbiomes on fertility and carbon cycling.

This theme will help us to better understand plant–soil interactions and sustainable agricultural practices and will contribute to global efforts to combat climate change by connecting fundamental plant science with applied research and ensuring the dissemination of knowledge that fosters innovation in crop and soil management.

The vast expanse of saline-alkali land in China represents a significant reserve of land resources for agricultural development. Therefore, it is essential to explore the saline-alkali tolerance of crops, the benefits of saline-alkali soil improvement, and their carbon sequestration potential. This study utilized the sorghum variety Jinliang 211 as the experimental material, conducting trials in saline-alkali woodland. A control and four different treatments combining organic fertilizers and soil amendments were established to investigate the effects of these mixtures on sorghum growth, antioxidant enzyme activity, soil improvement, and carbon sequestration characteristics. The results indicated that the combined application of organic fertilizer and rice husk biochar could enhance the salt tolerance of Jinliang 211, improve soil quality, and increase soil carbon sequestration capacity. Among the measured plant indicators, the T2 treatment (combined application of organic fertilizer and rice husk biochar) resulted in the highest dry matter accumulation, which was 68.4% higher than the control. Concurrently, the activities of antioxidant enzymes such as SOD, POD, and CAT significantly increased during the jointing stage post-treatment, with the highest enzyme activities observed in the T2 treatment. Regarding soil indicators, the soil organic carbon content initially increased and then decreased, with the T2 treatment showing the highest soil organic carbon content, 9.8% higher than the control. The soil pH initially decreased and then increased, with the T2 treatment exhibiting the lowest soil pH, 5.6% lower than the control. Importantly, the T2 treatment demonstrated the most pronounced “net carbon sink” characteristics in the soil. In summary, the T2 mixed treatment performed the best in enhancing sorghum antioxidant enzyme activity, increasing dry matter accumulation, and strengthening the carbon sequestration characteristics of saline-alkali soil.
