“…Besides, the soil water holding capacity, nutrient retention, soil structure, soil organic carbon sequestration, and cation exchange capacity were all increased after biochar application (Pereira et al 2015;Xu et al 2014;Zhang et al 2015). In addition, nitrogen/phosphorus use efficiencies of grain and zucchini plants were enhanced by biochar (Amin and Eissa 2017;Sun et al 2019b). However, drawbacks of soil application of biochar were also reported.…”

“…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.

“…Amylose content varied with different rice varieties in this study. The environment can influence crop grain quality [24], and particularly, the amylose content and the temperature and incident radiation were different in ES and LS [25]. For nonwaxy rice amylose content is higher in LS than ES [26].…”

Amylose content and starch granule size in grains influence rice quality, which differs between the early (ES) and late season (LS). The objective of this study was to determine the variation of amylose content and starch granule size between seasons and find the main reasons (e.g., temperature and solar radiation) for the observed variation. Field experiments with six rice varieties (three high and three low amylose content rice) planted in the ES and LS were conducted in 2016 and 2017, respectively. The mean temperatures during the filling stage were higher in ES, however, the daily temperatures at 7-10 days after flowering (DAF) in 2016, and at 5-10, 13-14 DAF in 2017 were higher in LS. The results showed that amylose content in LS was lower than in ES with high amylose content rice varieties (HACV); the opposite trend occurred with low amylose content rice varieties (LACV). The mean starch granule diameter was higher in LS than ES in 2016, but the opposite result occurred in 2017 with all rice. Our results suggest that higher temperatures increased and decreased the amylose content in HACV and LACV, respectively. Temperatures at 5-15 DAF were important for the formation of starch granules: lower temperatures during 10-14 DAF increased the proportion of larger starch granules (d＞6.21 μm, some with d＞13.3 μm), and higher temperatures at 5-6 DAF increased the proportion of starch granules with diameter 4.24-6.21 μm.

“…Furthermore, The N use efficiency was calculated as the percentage of applied fertilizer N recovered in aboveground biomass minus that of the control treatment without N fertilizer application (H. Sun et al, 2019a). The N content of aboveground biomass in the control treatment without N fertilizer application was 1.18 g pot -1 .…”

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.
