Effect of integrated application of biochar and microbes on (A) total nitrogen, (B) total phosphorous, (C) available phosphorous, and (D) available potassium under cadmium (Cd) stress. Bars are representing means ± standard deviation (SD) of three replication. Means within a column followed by the same letters are not significantly different at P ≤ 0.05. BC = biochar types; Cd = artificial cadmium stress; MI = microbial inoculation; BC0 = zero biochar; BC1 = maize-straw synthesized biochar, BC2 = cow-manure synthesized biochar; BC3 = poultry-manure synthesized biochar; MI0 = no microbial inoculation; MI1 = Trichoderma harzianum (fungus) microbial inoculation; MI2 = Bacillus subtilis (bacteria) microbial inoculation; MI3 = combined Trichoderma harzianum and Bacillus subtilis microbial inoculation; Cd0 = 0 ppm Cd; Cd1 = 10 ppm Cd; Cd2 = 30 ppm Cd.
