“…It found that main effect of biochar dosing has medium level effect on AHR. As biochar dosing increased from 25 to 50 g, 27.1% heating rate increased under MW heating owing to higher amount of biochar provided maximum number of hot spots compared to lower amount of biochar 22 , 31 . Further, another parameter particle size (mm) had little effect on AHR, this may be attributed due to the porosity and surface area of used biochar closely varying means biochar produced from single biomass (hardwood).…”

Microwave (MW) heating has gained significant attention in food industries and biomass-to-biofuels through pyrolysis over conventional heating. However, constraints for promoting MW heating related to the use of different MW absorbers are still a major concern that needs to be investigated. The present study was conducted to explore the MW heating performance of biochar as a low-cost MW absorber for performing pyrolysis. Experiments were performed on biochar under different biochar dosing (25 g, 37.5 g, 50 g), MW power (400 W, 700 W, 1000 W), and particle sizes (6 mm, 8 mm, 10 mm). Results showed that MW power and biochar dosing significantly impacted average heating rate (AHR) from 17.5 to 65.4 °C/min at 400 W and 1000 W at 50 g. AHR first increased, and then no significant changes were obtained, from 37.5 to 50 g. AHR was examined by full factorial design, with 94.6% fitting actual data with predicted data. The model suggested that the particle size of biochar influenced less on AHR. Furthermore, microwave absorption efficiency and biochar weight loss were investigated, and microwave absorption efficiency decreased as MW power increased, which means 17.16% of microwave absorption efficiency was achieved at 400 W rather than 700 W and 1000 W. Biochar weight loss estimated by employing mass-balance analysis, 2–10.4% change in biochar weight loss was obtained owing to higher heating rates at higher powers and biochar dosing.

“…Excessive chemical fertilization usually leads to soil salinity increase [8] . Recent researches adopted the traditional fertilization practices to improve soil organic inputs by using organic amendments [9,10] . Biochar (BC) is a carbon-rich product by pyrolysis in the closed system under a limited quantity of oxygen [10] .…”

Establishing strategies of organic amendments application to mitigate the adverse effects of saline irrigation are essential for the sustainable agriculture. A two-year pot experiment was conducted using combinations of organic amendments including effective microorganisms (EM), biochar (BC) and digestate (Di) to investigate their effects on soil and melon (Cucumis melo L.) compared with the recommended NPK fertilizer and Control (CK) under two levels of irrigation water salinity (SL0: 0.25 dS/m, SL1: 2.0 dS/m). Results showed combined applications of organic amendments could significantly (p<0.05) increase soil pH and organic matter (OM) compared to NPK and CK. Application of organic amendments containing BC evidently increased the sodium adsorptive capacity (SAC) under saline water solution. The combined application of EM, BC and Di (EM+BC+Di) could significantly (p<0.05) improve soil available water retention under SL0 and SL1 compared with other treatments. Results also showed organic amendments application can significantly (p<0.05) enhance the photosynthetic rate (Pr) and reduce sodium ion (Na + ) content in melon leaves. EM+BC+Di could significantly (p<0.05) increase water use efficiency (WUE) and fruit yield of melon under SL0 and SL1 in comparison to other treatments. It proved that EM+BC+Di had a positive effect on soil improvement, melon growth, WUE and fruit yield. Moreover, EM+BC+Di could be used as an alternative strategy for mineral NPK fertilization of melon at reasonable dosages and frequencies under saline irrigation.
