干旱区生态环境知识资源中心

Prediction of Nitrogen (N) mineralization from soil Organic Matter (OM) is important when we try to optimize N fertilization and assess adverse N impacts on the environment. The focus of this research study was to investigate throughout a field and laboratory approach, the influence of the pedoclimate and some soil properties on N mineralization dynamics in four non-amended soils of a semi-arid zone in North Tunisia. The aim was also to propose a classification according to their potential N mineralization and kinetics.
