Allelochemicals can act as biopesticides or enhance the action of synthetic pesticides. In this work, we assessed the bioavailability of the allelochemical coumarin in soils amended with fresh or field‐aged biochars (BCs). The fresh BC from oak wood (Fresh BC) was prepared at 550 °C and was buried for aging in two different places: in a sandy loam soil in Spain for 15 months (Aged BC_1) and a sandy loam soil in USA for six months (Aged BC_2).

生物炭改变了农业土壤中化感香豆素的生物利用度和生物功效。

化感物质可以充当生物农药或增强合成农药的作用。在这项工作中，我们评估了用新鲜或田间生物炭（BCs）改良过的土壤中化感化学香豆素的生物利用度。在550°C的温度下，由橡木制成的新鲜BC（新鲜BC）在两个不同的地方埋藏以进行老化：在西班牙的砂壤土中放置15个月（BC_1岁），在美国的砂壤土中放置6个月。（BC_2岁）。
