The Australian Site Networkntly measured as 31% of the total soil organic carbon pool for samples taken during the course of the trials from a wide variety of crop and ley farming treatments. The majority of this protected organic matter fraction has been identified by .C NMR as charcoal, a largely inert form of carbon.作者: 確定 時間: 2025-3-22 00:50

Why evaluate soil organic matter models?n SOM content, composition or dynamics can have far reaching impacts. Some changes occur slowly over periods of decades so long-term experiments are necessary to measure them.
