Biochar addition to soil has been reported to reduce the microbial degradation of pesticides due to sorption of the active compound. This study investigated whether the addition of hardwood biochar alters the mineralization of (14)C-labeled atrazine in two atrazine-adapted soils from Belgium and Brazil at different moisture regimens. Biochar addition resulted in an equally high or even in a significantly higher atrazine mineralization compared to the soils without biochar. Statistical analysis revealed that the extent of atrazine mineralization was more influenced by the specific soil than by the addition of biochar. It was concluded that biochar amendment up to 5% by weight does not negatively affect the mineralization of atrazine by an atrazine-adapted soil microflora.
生物炭添加到土壤中被报道可以减少农药的微生物降解，因为活性化合物被吸附。本研究调查了在不同水分条件下，添加硬木生物炭是否会改变比利时和巴西的两种适应莠去津的土壤中（14）C 标记莠去津的矿化。与不含生物炭的土壤相比，生物炭的添加导致莠去津的矿化程度同样高，甚至更高。统计分析表明，莠去津矿化的程度更多地受到特定土壤的影响，而不是生物炭的添加。结论是，生物炭的添加量最高可达 5%（重量比）不会对莠去津适应土壤微生物区系的矿化产生负面影响。
