Abstract	The soil organic carbon (SOC) is important for determining the chemical properties that are an essential source of nutrients for crops and natural resource. The study of their accumulation or loss is related to soil properties that support crops, such as fertility. In this sense, its study is crucial to explain the factors that favor its destabilization, especially when soils are being affected by disturbances like the burning of crop residues and floods for irrigation, which are usual in certain rice producing regions. The current study evaluated the effect of some chemical properties on SOC content by different spatial regression models and using 403 sampling points. The only significant chemical property in lag was Zn; and Ca, Mg, K, Cu and Zn in natural condition, with greater association for Ca. This suggests that the SOC is spatially related mainly to the content of Ca in rice producing areas of Norte de Santander. Thus, SOC management plans through fertilization can be done by controlling the application of soil elements showing a relationship. The recognition of the importance of these properties can be useful in site-specific management of fertilization and in the evaluation of soil quality.
