“…Obviously, the impact of biochar on soil physicochemical properties and plant productivity was significantly correlated with the type of biochar and soil. Besides, the effect of biochar on plant productivity was concentrated on grain crops such as wheat (Sun et al 2019b;Sun et al 2019c), rice (Liu et al 2019;Moiwo et al 2019), and maize (Cazotti Tanure et al 2019;Sun et al 2019a). Little research was conducted to study the impact of biochar from tobacco straw (TS) on the physicochemical properties of tobacco-growing (TG) soil and the tobacco productivity.…”

The purpose of this study was to investigate the response of physicochemical properties of tobacco-growing soils and N/P/K accumulation of tobacco plant to tobacco straw biochar. Two contrasting tobacco-growing soils of paddy soil (Ultisol in USDA taxonomy) and brown soil (Alfisol in USDA taxonomy) were selected to conduct the pot experiments. Five addition rates (w/w) of tobacco straw biochar of 0%, 1%, 2%, 4%, and 10% without or with tobacco (Nicotiana tabacum) were applied in a greenhouse. The 7.41-35.90% increase of soil field capacity, 0.71-15.11% increase of total porosity, 3.40-17.55% increase of capillary porosity, 15.98-293.13% increase of organic matter, 6.52-58.75% increase of available phosphorus, 109.07-1789.70% increase of potassium, 3.23-147.71% increase of exchangeable cation, and 12.13-48.48% increase of soil pH were observed after biochar addition. And this improvement increased with the increasing application rate. The same trend was also found in the tobacco N/P/K uptake in the biochar application range of 0-4% and subsequently decreased at 10% rate. Meanwhile, biochar decreased the soil bulk density of 0.68-14.06%. The step regression equation showed that the exchangeable potassium and aluminum for Ultisol as well as the exchangeable potassium and hydrogen for Alfisol were the predominant factors that determined the soil pH. According to the PCA results, exchangeable calcium > exchangeable potassium > exchangeable cation > pH > organic matter > exchangeable magnesium > available potassium > available phosphorus and organic matter > exchangeable potassium > available phosphorus > exchangeable cation > available potassium > pH > exchangeable calcium had a significant impact on soil fertility of Ultisol and Alfisol, respectively. Finally, a comprehensive evaluation of soil fertility by PCA revealed that ST10 (10% rate, w/w) performed best, followed by the ST4 (4% rate, w/w) in both soils. The application of tobacco straw biochar, with appropriate rate, is an effect method to improve physicochemical properties of tobacco-growing soil and N/P/ K uptake of tobacco plant.

“…The introduction of more N and H sources into soil, together with an increase in pore conductivity that allows for gas exchange, may be important factors for promoting NH3 volatilization, as shown in previous studies on biochars (Sun et al, 2017;Feng et al, 2018b;H. Sun et al, 2019b).…”

“…Generally, biochar application can reduce soil pH, and increase porosity, aeration, and redox potential, thus reducing NH3 volatilization or N2O emission by altering soil properties such as NH4 + -N adsorption and activity of nitrobacterium and denitrobacterium (Nelissen et al, 2014;Feng et al, 2017;Mandal et al, 2019;. However, these controversial results also indicate that biochar application can potentially promote NH3 volatilization (Sun et al, 2017;Feng et al, 2018b;H. Sun et al, 2019b) or N2O emissions (Duan et al, 2018;Senbayram et al, 2019;, depending on different properties of soil or feedstock of biochars.…”

Hydrothermal carbonization represents a promising technique for transforming microalgae into the hydrochar with abundant phytoavailable nutrients. However, the effects of microalgae-derived hydrochars on the gaseous nitrogen (N) loss from agricultural field are still unclear. Chlorella vulgaris powder (CVP) and two Chlorella vulgaris-derived hydrochars that employ water (CVHW) or citrate acid solution (CVHCA) as the reaction medium were applied to a soil column system grown with rice. The temporal variations of nitrous oxide (N2O) emissions and ammonia (NH3) volatilization were monitored during the whole rice-growing season. Results showed that CVHW and CVHCA addition significantly increased the grain yield (by 13.5-26.8% and 10.5-23.4%) compared with control and CVP group, while concomitantly increasing the ammonia volatilization (by 53.8% and 72.9%) as well as N2O emissions (by 2.17-and 2.82-fold) from paddy soil compared to control. The microbial functional genes (AOA, AOB, nirk, nirS, nosZ) in soil indicated that CVHW and CVHCA treatment stimulated the nitrification and denitrification, and inhibited the N2O oxidation in soil. Notably, CVHW was recommended in the view of improving yield and controlling NH3 volatilization because no significant difference of the yield-scale NH3 volatilization was detected between control and CVHW treatment. This study for the first time uncovered that Chlorealla vulgaris-derived hydrochars have positive effects on rice N utilization and growth but negative effects on the atmospheric environment.

“…Compared with soils planted with other plants/cropping systems, most intensively managed plantation forest soils have relatively lower soil pH [7,19]. According to previously reported data, biochar can have lower pH depending on feedstock, temperature, etc., however, they are typically greater than 8.0 [15,20]. Here, we hypothesize that alkaline biochar addition can decelerate the acidifying processes of N-applied intensively managed forest soils.…”

Intensive practices in forest soils result in dramatic nitrogen (N) losses, particularly ammonia (NH3) volatilization, to adjacent environmental areas. A soil column experiment was conducted to evaluate the effect of bamboo biochar on NH3 volatilization from tea garden and bamboo forest soils. The results showed that biochar amendment effectively reduced NH3 volatilization from tea garden and bamboo forest soil by 79.2% and 75.5%, respectively. The soil pH values increased by 0.53-0.61 units after biochar application. The NH4 +-N and total N of both soils were 13.8-29.7% and 34.0-41.9% higher under the biochar treatments than under the control treatment, respectively. In addition, the soil water contents of the two biochar-amended soils were significantly higher (P < 0.05), by 10.7-12.5%, than that of the soils without biochar amendment. Therefore, biochar mitigates NH3 volatilization from the tested forest soils, which was due to the increases in soil NH4 +-N, total N and water contents after biochar amendment. Our main findings suggest that biochar addition is an effective management option for sustainable forest management.
