原文摘要

Twenty seven methods currently used to characterize biochar were assessed in terms of their usefulness to determine the stability of biochar carbon in the environment. The International Biochar Initiative (IBI), which led the effort, gathered fourteen world-class experts in different fields of biochar relevant to stability, who guided the process for obtaining a simple, yet reliable, measure for biochar stability. Important requisites were defined for the test, including cost, repeatability and availability. Identification of a cost-effective, scientifically valid test to measure the stable carbon component of biochar is imperative to distinguish biochar from non-biochar (non-stable) materials, and to develop a biochar offset protocol for carbon markets. The stability of biochar carbon in soils makes it a highly promising product for consideration as a strategy for climate change mitigation. The definition of the variable BC+100, which stands for the amount of biochar carbon that is expected to remain stable after 100 years, along with predictions of stability based on simple (Alpha) and more sophisticated (Beta) methods, allowed to correlate a molar ratio (H/Corg) to the relative stability of biochar. The process for identifying the Biochar Carbon Stability Test Method is summarized here, and the method itself is available as a separate, technical document.

原文摘要簡述

目前用於表徵生物炭的27種方法是根據其用於確定生物炭在環境中的穩定有用性進行評估。領導這項工作的國際生物炭倡議組織(IBI)聚集了14位不同領域與生物炭穩定相關的世界級專家,他們指導了獲得簡單而可靠的生物炭穩定性措施的過程。為測試定義了重要的必要條件,包括成本,可重複性和可用性。確定用於測量生物炭穩定碳成分的有效經濟與科學性的測試,對於區分生物炭和非生物炭(非穩定)材料以及製定碳市場的生物炭 offset protocol是不可或缺的。生物炭在土壤中的穩定性使其成為一種非常有前途的產品,??可作為減緩氣候變化的戰略。變量BC + 100的定義,代表預計在100年後保持穩定的生物炭碳量,以及基於簡單(Alpha)和更複雜(Beta)方法的穩定性預測,允許關聯摩爾比(H / Corg)與生物炭的相對穩定性。此處總結了用於識別Biochar碳穩定性測試方法的過程,並且該方法本身可提供作為單獨技術文件檔案。
