Abstract: In an energy‐limited world, biomass may be converted to energy products through pyrolysis. A byproduct of this process is biochar. A better understanding is needed of the sorption characteristics of biochars, which can influence the availability of plant essential nutrients and potential water contaminants such as phosphorus (P) in soil. Knowledge of P retention and release mechanisms when applying carbon‐rich amendments such as biochar to soil is needed. The objectives of this study were to quantify the P sor… Show more

“…The increase in alkali phosphatase activity by biochar amendment could have been due to a chemical enhancement of enzyme function caused by the interaction with biochar (Jindo et al 2012). In our study, the addition of biochar reduced protease activity in soil, which may be due to a decreased availability of inorganic N (Chintala et al 2014). Protease activity was different from the previous study reported by Oleszczuk et al (2014).…”

“…These ions developed liming ability in biochar and make it preferable amendment for soil reclamation. Similar types of results were also note by Novak et al, 2009. Chintala et al (2013 noted that Ponderosa pine wood residues biochar had higher bicarbonate ions that play a vital role in the extraction of soil phosphorus.…”

“…Phosphorus contents in above-ground biomass of maize increased with increasing BC application rates. According to Chintala et al (2014) and Zhang et al (2016a), the ability of BC to increase P retention in soils is quite variable and it varies with concentration of P in the soil solution. Although the Mehlich IIIavailable contents of Fe and P increased with BC application (Table 2), only Fe was not accumulated into plant tissues.…”
