Cover Story: This issue features the study "On-Site Determination of Soil Organic Carbon Content: A Photocatalytic Approach". Researchers introduced a novel method for evaluating soil organic carbon (SOC) using a photoelectrochemical oxygen demand (PeCOD) analyzer and geographic information system technology. The study found that the PeCOD system reliably assessed SOC through photochemical oxidation, correlating well with traditional methods. Finer soils had higher SOC content, influenced by land management, precipitation, and temperature. This innovative approach provides valuable insights for sustainable farming, climate change mitigation, and soil health, offering farmers effective strategies to enhance carbon sequestration and improve soil quality.
