This study was carried out to assess the ecotoxicity of soil affected by wildfire using two laboratory toxicity tests, and to investigate the possibility of application of selected soil amendment into the burnt soil in order to improve its properties for faster post-fire reclamation. A phytotoxicity test is a fast-indicative test for revealing acute toxicity and was performed on quickly growing plant species Sinapis alba L. and Lepidium sativum L., while a pot experiment is a standardized toxicity test with a longer experiment duration and was carried out with Lolium perenne L., Festuca rubra L., Brassica juncea L. Diatomite, bentonite, compost, and biochar were supplemented to the soil. Regarding the phytotoxicity test only 3% w/w of biochar stimulated the growth of Lepidium sativum L. Pot experiment confirmed that effect of soil application amendments on biomass yield is more significant than the plant species. The average highest biomass yields were achieved in treatments with bentonite and diatomite. Subsequent research should focus on investigating possible combinations of soil amendments for burnt soil reclamation and complementing the experiments with chemical analysis.

评估受野火影响的土壤的生态毒性

这项研究是使用两个实验室毒性测试来评估受野火影响的土壤的生态毒性，并研究将选定的土壤改良剂应用到燃烧的土壤中的可能性，以改善其特性，以便在火灾后更快地进行开垦。植物毒性试验是用于揭示急性毒性的快速指示性试验，是对快速生长的植物西纳皮猪和小菜蛾进行的，盆栽试验是标准的毒性试验，具有较长的试验时间，并且在黑麦草Perenne L.，Festuca rubra L.，芸苔将硅藻土，膨润土，堆肥和生物炭补充到土壤中。对于只有3％的药害试验W¯¯ / w ^生物炭的刺激增长独行菜豌豆L.盆栽实验证实土壤施用修订的生物质产量，从效果比植物种类更显著。用膨润土和硅藻土处理可达到平均最高生物量产量。随后的研究应侧重于研究可能的土壤改良剂组合以用于烧毁的土壤开垦，并用化学分析对实验进行补充。
