Abstract
Crop-assimilated carbon (C), an important source of soil organic carbon (SOC), represents a key linked component of the C cycle in the soil-plant-atmosphere continuum. In the farmland ecosystem, however, the quantitative characterization and mechanism involved in the distribution and transformation of the assimilated C in soil over the plant's life cycle are problems relatively easily ignored. Research in this area is therefore indispensable for a thorough understanding of the process and characteristics of the organic C cycle in farmland soil. This paper provides an overview on: (1) the distribution, transformation rules, and structural features of crop-assimilated C in soil and its contribution to SOC and the function of microorganisms in the transformation of assimilated C. (2) The chemical compositions and structural features of the assimilated C after its entry into soil organic matter. (3) The relationship between assimilated C, rhizosphere deposition, and C isotope technology. Based on the findings, we consider that further research on the distribution of crop-assimilated C in the soil-crop system and the quantitative relations of several C-transformation steps such as crop input, transformation, protection, and stabilization in different ecosystems should be conducted. Moreover, the component and structure of 'new C' input into the soil by rhizosphere
