Biochar (BC) produced from oak sawdust by slow pyrolysis was investigated to check the potential inhibition to early growth of tomato for phytotoxicity assessment. An inverted-U-shaped dose-response relationship between BC dosage and seed germination/seedling growth can be observed. Half maximal effective concentration (EC50), based on the inhibition rate of root and stem length, was 65.7 and 74.0 g kg−1, respectively. At the highest BC dosage of 80.0 g kg−1, germination rate, root, and shoot… CONTINUE READING
