The objective of this study was to investigate the effect of different
pyrolysis temperatures on the properties of produced bovine bone char
and to evaluate their suitability as phosphorus resources in P-poor sandy
soil. An incubation experiment was performed and comprised of five
treatments: unamended soil (CK), soil amended with the bovine bone
(SBB), soil amended with bovine bone char at 300 °C (SBBC300), soil
amended with bovine bone char at 500 °C (SBBC500), and soil amended
with bovine bone char at 700 °C (SBBC700). Our findings demonstrate that
pyrolysis temperature greatly affects the chemical properties of bovine
bone char. The results obtained from the incubation experiments showed
that adding bovine bone char produced at different temperatures significantly increased Olsen-P in P-poor sandy. Olsen-P concentrations
increased significantly with increasing incubating period. The highest
Olsen-P values existed in SBBC500 treatment at all incubation periods.
Compared to unamended soil, adding SBBC500 to the soil increased
Olsen-P by 41.7%, 42.9%, 35.5%, and 31.6% after 7, 15, 29, and 47 days
of incubation, respectively. Consequently, use of bovine bone char produced at 500 °C may be an alternative option for phosphorus as
a renewable, economical, and environmentally friendly source.
