“…32,33 The pH values of the MP increased from 6.87 at 300 C to 9.06 at 700 C. Previous studies have also showed that biochar produced at higher temperatures exhibited a higher pH. 34,35 This is due to the degradation of acidic functional groups and the accumulation of inorganics during pyrolysis. 36 As the pyrolysis temperature increased, C content increased from 51.33% in MK to 78.61% in MP700, but contents of O, H and N and ratios of H/ C, O/C and (O + N)/C in MP decreased, suggesting that the volatile components, which form a large fraction of the surface functional group elements (H, N, and O), were gradually lost during pyrolysis.…”

“…Biochar also increased organic carbon in saline soil, supporting favourable conditions for soil microbes involved in nutrient cycles [16]. Tang et al [17] also observed biochar-induced improvements in soil physical-chemical properties, which mitigated salt stress during seedling growth of Brassica chinensis L. Moreover, the soil under saline conditions amended with biochar experienced increased enzymatic activities such as of urease, invertase and phosphatase [18].…”

Licorice (Glycyrrhiza uralensis Fisch.) is a salt and drought tolerant legume suitable for rehabilitating abandoned saline lands, especially in dry arid regions. We hypothesized that soil amended with maize-derived biochar might alleviate salt stress in licorice by improving its growth, nutrient acquisition, and root system adaptation. Experiments were designed to determine the effect of different biochar concentrations on licorice growth parameters, acquisition of C (carbon), nitrogen (N), and phosphorus (P) and on soil enzyme activities under saline and non-saline soil conditions. Pyrolysis char from maize (600 °C) was used at concentrations of 2% (B2), 4% (B4), and 6% (B6) for pot experiments. After 40 days, biochar improved the shoot and root biomass of licorice by 80 and 41% under saline soil conditions. However, B4 and B6 did not have a significant effect on shoot growth. Furthermore, increased nodule numbers of licorice grown at B4 amendment were observed under both non-saline and saline conditions. The root architectural traits, such as root length, surface area, project area, root volume, and nodulation traits, also significantly increased by biochar application at both B2 and B4. The concentrations of N and K in plant tissue increased under B2 and B4 amendments compared to the plants grown without biochar application. Moreover, the soil under saline conditions amended with biochar showed a positive effect on the activities of soil fluorescein diacetate hydrolase, proteases, and acid phosphomonoesterases. Overall, this study demonstrated the beneficial effects of maize-derived biochar on growth and nutrient uptake of licorice under saline soil conditions by improving nodule formation and root architecture, as well as soil enzyme activity.

“…NPQ mainly comprises regulated and non-regulated energy dissipation and indicates that the light energy absorbed by PSII antenna pigments cannot be used for photochemical electron transfer, which dissipates as heat (Long et al, 2013;Perkins et al, 2018). Tang et al (2020) reported that biochar pyrolyzed at 600 • C increased qP and decreased NPQ, relative to the no-biochar treatment. Our results showed that B10 and B20 improved qP at flowering and pod set, and reduced NPQ at pod set in both years (Figure 2).…”

The effect of biochar application on photosynthetic traits and yield in peanut (Arachis hypogaea L.) is not well understood. A 2-year field experiment was conducted in Northwest Liaoning, China to evaluate the effect of biochar application [0, 10, 20, and 40 t ha−1 (B0, B10, B20, and B40)] on leaf gas exchange parameters, chlorophyll fluorescence parameters, and yield of peanut. B10 improved photochemical quenching at flowering and pod set and reduced non-photochemical quenching at pod set, relative to B0. B10 and B20 increased actual photochemical efficiency and decreased regulated energy dissipated at pod set, relative to B0. B10 significantly increased net photosynthetic rate, transpiration rate, stomatal conductance, and water use efficiency at flowering and pod set, relative to B0. Compared with B0, B10 significantly improved peanut yield (14.6 and 13.7%) and kernel yield (20.2 and 14.4%). Biochar application increased leaf nitrogen content. B10 and B20 significantly increased plant nitrogen accumulation, as compared to B0. The net photosynthetic rate of peanut leaves had a linear correlation with plant nitrogen accumulation and peanut yield. The application of 10 t ha−1 biochar produced the highest peanut yield by enhancing leaf photosynthetic capacity, and is thus a promising strategy for peanut production in Northwest Liaoning, China.
