| Abstract | ||
| Due to its distinctive properties, biochar (BC) achieves the most significant improvements among agricultural soil amendments. A pot experiment was performed at the Faculty of Agriculture and Natural Resources at Aswan University, Aswan province, Egypt (latitudes 24° 05ʹ 18ʺ N and longitudes 32° 54ʹ 00ʺ E) during 2022 to evaluate the effectiveness of two BCs derived from sugarcane manufacturing waste—namely, bagasse (BCBG) and filter-cake (BCFC), which were obtained at two different of pyrolysis temperatures (300 and 600 °C) at 0, 1 and 2% ~ 0.0, 50.0 and 100.0 g.pot-1 on the hydro-chemical properties of sandy soil. This study employed a split–split plot structure in a Randomized Complete Block Design with three replicates. The results indicate that applying BCFC300 had the greatest effect on organic matter content (OM) and available water content (AWC), while applying BCFC600 gave the best results for CaCO3, as well as water holding capacity (WHC) and permanent wilting point (PWP). Likewise, BCBG300 had superior effects on soil pH and cation exchange capacity (CEC) and field capacity (FC). Furthermore, all the improvements seen in all the studied hydro-chemical properties, except PWP, were associated with BC-R0 and BC-R2. In conclusion, BCBG, PYT300 and BC-R2 and their interactions were the most influential on soil chemical properties. Furthermore, the best hydrological properties (FC and AWC) in the sandy soil were obtained in the treatment without amendment. Additionally, BCFC x PYT600 x BC-R2 and BCFC x PYT600 x BC-R2 treatments were the most impactful on WHC and PWP, respectively. | ||
