Organic acids, vitamins, and carbohydrates represent important organic compounds in soil. Aliphatic, cyclic, and aromatic organic acids play important roles in rhizosphere ecology, pedogenesis, food-web interactions, and decontamination of sites polluted by heavy metals and organic pollutants. Carbohydrates in soils can be used to estimate changes of soil organic matter due to management practices, whereas vitamins may play an important role in soil biological and biochemical processes. The aim of this work is to review current knowledge on aliphatic, cyclic, and aromatic organic acids, vitamins, and carbohydrates in soil and to identify directions for future research. Assessments of organic acids (aliphatic, cyclic, and aromatic) and carbohydrates, including their behaviour, have been reported in many works. However, knowledge on the occurrence and behaviour of D-enantiomers of organic acids, which may be abundant in soil, is currently lacking. Also, identification of the impact and mechanisms of environmental factors, such as soil water content, on carbohydrate status within soil organic matter remains to be determined. Finally, the occurrence of vitamins in soil and their role in biological and biochemical soil processes represent an important direction for future research.
有机酸、维生素和碳水化合物是土壤中的重要有机化合物。脂肪族、环状和芳香族有机酸在根际生态学、土壤发生、食物网相互作用以及重金属和有机污染物污染场地的净化中发挥着重要作用。土壤中的碳水化合物可用于估算因管理措施导致的土壤有机质变化，而维生素可能在土壤生物和生化过程中发挥重要作用。这项工作的目的是综述当前关于土壤中脂肪族、环状和芳香族有机酸、维生素和碳水化合物的知识，并确定未来的研究方向。许多研究已经报道了对有机酸（脂肪族、环状和芳香族）和碳水化合物的评估，包括它们的行为。然而，目前缺乏关于土壤中可能大量存在的有机酸D-对映体的存在和行为的知识。此外，环境因素如土壤含水量对土壤有机质中碳水化合物状况的影响及其机制仍有待确定。最后，土壤中维生素的存在及其在土壤生物和生化过程中的作用是未来研究的一个重要方向。
