“…Biochar can be used not only as a soil amendment with the aim of improving soil physical, chemical and biological properties [4,5], but also as an adsorbent to remove organic and inorganic pollutants [6,7]. The functions and applications of biochars mostly depend on their structural and physicochemical properties [8], therefore, it is very important to characterize the structural and physicochemical properties of biochar before its use.…”

Abstract:The objective of this study was to study the structure and physicochemical properties of biochar derived from apple tree branches (ATBs), whose valorization is crucial for the sustainable development of the apple industry. ATBs were collected from apple orchards located on the Weibei upland of the Loess Plateau and pyrolyzed at 300, 400, 500 and 600 • C (BC300, BC400, BC500 and BC600), respectively. Different analytical techniques were used for the characterization of the different biochars. In particular, proximate and element analyses were performed. Furthermore, the morphological, and textural properties were investigated using scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, Boehm titration and nitrogen manometry. In addition, the thermal stability of biochars was also studied by thermogravimetric analysis. The results indicated that the increasing temperature increased the content of fixed carbon (C), the C content and inorganic minerals (K, P, Fe, Zn, Ca, Mg), while the yield, the content of volatile matter (VM), O and H, cation exchange capacity, and the ratios of O/C and H/C decreased. Comparison between the different samples show that highest pH and ash content were observed in BC500. The number of acidic functional groups decreased as a function of pyrolysis temperature, especially for the carboxylic functional groups. In contrast, a reverse trend was found for the basic functional groups. At a higher temperature, the brunauer-emmett-teller (BET) surface area and pore volume are higher mostly due to the increase of the micropore surface area and micropore volume. In addition, the thermal stability of biochars also increased with the increasing temperature. Hence, pyrolysis temperature has a strong effect on biochar properties, and therefore biochars can be produced by changing pyrolysis temperature in order to better meet their applications.

“…Recent research has identified several environmental and agricultural benefits of applying biochar, including carbon sequestration for reducing carbon emission into the atmosphere (Mašek et al, 2013;Mukherjee and Lal, 2013;Zhang and Ok, 2014;Jiang et al, 2016;Wang et al, 2016); phytoremediation of soil contaminants (Ahmad et al, 2014;Mohan et al, 2014;Wiszniewska et al, 2016); adjusting soil physicochemical and biochemical properties for agriculture (Herath et al, 2013;Githinji, 2014;Bai et al, 2015;Abujabhah et al, 2016;Bera et al, 2016;Haider et al, 2017); creating soil health by inducing growth of beneficial and suppressing pathogenic organisms (Lone et al, 2015;Abujabhah et al, 2016;George et al, 2016;Xu et al, 2016); and improving crop growth and yield (Vaccari et al, 2015;Agegnehu et al, 2016).…”

Biochar improves soil quality. However, most biochar research has focused on aerobic soil conditions. The objective of this research was to evaluate the agronomic benefits of applying biochar on unfertilized rice crop, cultivated under transitional anaerobic soil conditions during early vegetative growth phase, and gradually drying out to fully aerobic at harvest time. This transitional condition is typical during the rice growing season of the tropical riparian wetlands in Indonesia. Biochar was applied in the form of fine powder at rates of 0, 0.4, 0.8, and 1.2 Mg.ha -1 ; no inorganic fertilizer was applied. The research was conducted on a farmer's paddy field at Pemulutan Ulu Village, South Sumatra, Indonesia from July to November 2016. Results indicated that applying biochar at rates up to 1.2 Mg.ha -1 increased rice yield, but restrained shoot elongation rate and plant height. During the vegetative growth phase, applying biochar significantly increased the number of tillers, leaves, shoot dry weight, and root dry weight. Biochar significantly affected the following yield components: number of tillers, percentage of productive tiller, number of grains per panicle, panicle density, percentage of filled grain, and weight of 1,000 grains.

“…Pemberian arang kayu sengon pada dosis tertinggi (6%) mampu meningkatkan C-organik sebesar 49,27% dibandingkan dengan perlakuan tanpa arang hayati (Gambar 1b). Hasil ini relatif sejalan dengan yang dilaporkan oleh Abujabhah, Bound, Doyle, & Bowman (2016), bahwa pemberian arang hayati 47 ton ha -1 nyata meningkatkan C-organik dalam tanah sebesar 23% (dari 2,19% menjadi 2,69%), tetapi peningkatan ini masih lebih rendah bila dibandingkan dengan perlakuan kompos 10 ton ha -1 , yaitu sebesar 55%. Peningkatan C/N media pembibitan akibat pemberian arang kayu sengon dan pupuk organik berpotensi menyebabkan proses imobilisasi N. Upaya yang dapat dilakukan untuk menghindari pengaruh negatif proses imobilisasi N terhadap tanaman adalah melakukan pemupukan N untuk memenuhi kebutuhan tanaman (Schulz, Dunst, & Glaser, 2013).…”

“…Kelimpahan mikrob meningkat setelah penambahan arang hayati sampai dosis tertentu, namun pengaruh pupuk organik terhadap populasi mikrob lebih besar dibandingkan dengan arang hayati. Hasil penelitian lain juga menyebutkan bahwa pemberian arang hayati dapat meningkatkan jumlah bakteri tanah sebesar 15%, namun peningkatan tersebut masih lebih rendah jika dibandingkan dengan aplikasi kompos, yaitu 58% (Abujabhah et al, 2016). Hal ini terjadi karena adanya perbedaan sifat pupuk organik dan arang hayati, di antaranya: (1) pupuk organik lebih banyak mengandung senyawa karbon labil dibandingkan dengan arang hayati, dan (2) pupuk organik mengandung populasi mikrob yang relatif lebih tinggi dibandingkan dengan arang hayati sehingga dapat menjadi sumber inokulan di dalam media pembibitan.…”
