“…Wang et al (2011) reported that biochar incorporation (50 t ha -1 ) into paddy soils significantly decreased N 2 O emissions during the 60-day period by 73 %, while the inhibition ranged from 51 to 94 % (p\0.05-0.01) in terms of cumulative emissions. Wang et al (2012) reported that biochar application decreased N 2 O emissions up to 54 and 53 % during rice and wheat seasons. However, Clough et al (2010) and Kristiina et al (2011) found that biochar application had no effect on N 2 O emissions.…”

A field experiment was conducted in Bangladesh Agricultural University Farm to investigate the mitigating effects of soil amendments such as calcium carbide, calcium silicate, phosphogypsum, and biochar with urea fertilizer on global warming potentials (GWPs) of methane (CH 4 ) and nitrous oxide (N 2 O) gases during rice cultivation under continuous and intermittent irrigations. Among the amendments phosphogypsum and silicate fertilizer, being potential source of electron acceptors, decreased maximum level of seasonal CH 4 flux by 25-27 % and 32-38 % in continuous and intermittent irrigations, respectively. Biochar and calcium carbide amendments, acting as nitrification inhibitors, decreased N 2 O emissions by 36-40 % and 26-30 % under continuous and intermittent irrigations, respectively. The total GWP of CH 4 and N 2 O gases were decreased by 7-27 % and 6-34 % with calcium carbide, phosphogypsum, and silicate fertilizer amendments under continuous and intermittent irrigations, respectively. However, biochar amendments increased overall GWP of CH 4 and N 2 O gases.

“…As more volume was taken up by biochar, less starter nutrients were present in the initial mix. The field studies revealed that by amending biochar into soil, it introduced highly stable C into the soil that could reduce the net soil CO 2 equivalent emissions (CO 2 , NO 2 , and CH 4 ) [34][35][36]. The mechanisms involve biochar change in the physical, chemical, and biological environment of the soil [37].…”

A greenhouse study was conducted to evaluate the growth and development of poinsettia 'Prestige Red' (Euphorbia pulcherrima) grown in a commercial peat-based potting mix (Sunshine Mix #1) amended with biochar at 0%, 20%, 40%, 60%, 80%, or 100% (by volume) at four different fertigation regimes: F1: 100 to 200 mg·L −1 nitrogen (N), F2: 200 to 300 mg·L −1 N (control), F3: 300 to 400 mg·L −1 N, or F4: 400 to 500 mg·L −1 N. The experiment was a two-factor factorial design with 10 replications for each combination of biochar by fertigation. As the percentage of biochar increased, root substrate pore space and bulk density increased, while container capacity decreased. Root rot and red bract necrosis only occurred in F4 combined with 100% biochar. Plants grown in 40% biochar had a similar growth and development to those in 0% biochar. Up to 80% biochar, plants exhibited no significant change, except in terms of dry weight, which decreased at higher biochar percentages (60% and 80%). In summary, at a fertigation rate of 100 mg·L −1 N to 400 mg·L −1 N, up to 80% biochar could be used as an amendment to peat-based root substrate with acceptable growth reduction and no changes in quality.

“…Biochar application has been reported to reduce or have no effect on rice yield in fertile soils by enhancing the immobilization of inorganic nitrogen due to its high C/N ratio (Asai et al 2009;Haefele et al 2011;Xie et al 2013). On the other hand, in soils with low fertility, biochar increased rice yield by supplementing nutrients and improving soil physical and chemical properties (Wang et al 2012;Zhang et al 2012;. In our study, soil physicochemical properties such as pH, EC and nitrogen content were not improved by RC or RH application (Table 4).…”

“…The effects of biochar use on GHG emissions have been reported in many agricultural fields, but most of these studies were conducted in aerobic incubations or upland fields amended with wood-derived biochar (Rondon et al 2006;Spokas and Reicosky 2009;Singh et al 2010;Van Zwieten et al 2010;Scheer et al 2011;Wang et al 2012). Only a few studies have been conducted in anaerobic conditions or paddy fields Liu et al 2011;Feng et al 2012;Zhang et al 2012).…”

Biochar application has been recognized as an effective option for promoting carbon (C) sequestration, but it may also affect the production and consumption of methane (CH 4 ) and nitrous oxide (N 2 O) in soil. A 1-year field experiment was conducted to investigate the effects of rice husk charcoal application on rice (Oryza sativa L.) productivity and the balance of greenhouse gas exchanges in an Andosol paddy field. The experiment compared the treatments of rice husk charcoal applied at 10, 20 and 40 Mg ha −1 (RC10, RC20 and RC40, respectively), rice husk applied at 20 Mg ha −1 (RH20), and the control (CONT). Rice straw and grain yields did not significantly differ among the treatments. The seasonal cumulative CH 4 emissions were 38-47% higher from RC10, RC20 and RC40 than from the CONT. However, the increases were not in proportion to the application rates of rice husk charcoal, and their values did not significantly differ from the CONT. On the contrary, the RH20 treatment significantly increased the cumulative CH 4 emission by 227% compared to the CONT. The N 2 O emissions during the measurement were not affected by the treatments. As a result, the combined global warming potential (GWP) of CH 4 and N 2 O emissions was significantly higher in RH20 than in the other treatments. There was a positive linear correlation between C storage in the top 10 cm of soil and the application rate of rice husk charcoal. The increases in soil C contents compared to the CONT corresponded to 98-149% of the C amounts added as rice husk charcoal and 41% of the C added as rice husk. Carbon dioxide (CO 2 ) fluxes in the off season were not significantly different among RC10, RC20, RC40 and CONT, indicating that C added as rice husk charcoal remained in the soil during the fallow period. The CO 2 equivalent balance between soil C sequestration and the combined GWP indicates that the rice husk charcoal treatments stored more C in soil than the CONT, whereas the RH20 emitted more C than the CONT. These results suggest that rice husk charcoal application will contribute to mitigating global warming without sacrificing rice yields.
