“…The different contents of labile C in the seven treatments were also reflected from their distinct microbial responses. As reported by Ouyang and Zhang (2013), the MBC was significantly higher in the biochar treatments than in the control, which showed the stimulating effects of biochars on soil microbial activities. Similar results have been reported in the literature, mainly related to the availability of an easily decomposable, non-aromatic fraction of biochar (Steiner et al 2008;Kolb et al 2009;Kuzyakov et al 2009;Novak et al 2010).…”

“…A few small holes were pricked on the plastic sheet to keep atmosphere pressure inside the bottle. For each pot, deionised water was added to retain a volumetric water content of 80% of field water capacity (the water content at suction of 330 cm) determined based on the soil-water retention curve (Ouyang and Zhang 2013). During the incubation period, the soil water content was adjusted weekly based on weight loss.…”

“…The specific surface area (SSA), the pore volume, and the average pore size of the biochars were determined using N 2 sorption isotherms, using the Brunauer-Emmett-Teller (BET) method (Belsorp mini Π, BelJapan) (Zhang et al, 2012). Biochar pH was measured using a pH probe with a 1:5 (w/w) suspension of biochar in deionized water (Lei & Zhang, 2013). Cation exchange capacity (CEC) of biochar was determined by the summation of cations adsorbed to the biochar surface by replacing them with ammonium ions (Yuan et al, 2011).…”

“…Primarily, the number and size of pores is determined by the type of feedstock, temperature level and time of pyrolysis. The specific surface area (SSA) of biochar increases with temperature of pyrolysis (Lei and Zhang, 2013;Bornemann et al, 2007). At temperatures of 450 • C the SSA can be smaller than 10 m 2 g −1 , while at temperatures of 600-750 • C it can rise to around 400 m 2 g −1 (Kookana et al, 2011).…”
