From: Biochar aided priming of carbon and nutrient availability in three soil orders of India
Total C mineralized in 290 days incubations of soil alone (S), biochar alone (Q-BC), and biochar mixed with (a) Alfisol, (b) Inceptisol and (c) Mollisol (S-BC). The histograms followed different upper case (sum of S and Q-BC i.e. S + Q-BC), lower case (Q-BC), and upper case underline (S with BC i.e. S-BC) are significantly different as per Duncan’s Multiple Range Test at P = 0.05; * indicates significant difference between sum of S and Q-BC (S + Q-BC) with S and BC mixture (S-BC) at P = 0.05 (Paired T test, n = 3 pairs) and ns indicates non-significant difference between these; Each histogram represents mean ± standard error (n = 3); RBC4-Rice husk biochar prepared at 400 °C; RBC6-Rice husk biochar prepared at 600 °C; SBC4-Sugarcane bagasse biochar prepared at 400 °C; SBC6-Sugarcane bagasse biochar prepared at 600 °C; MBC4-Mustard stalk biochar prepared at 400 °C; MBC6-Mustard stalk biochar prepared at 600 °C.
