“…Similarly, Sun and Lu [38] reported that the application of biochar to the soil significantly increased the available N and P content of soils. However, according to Arthur et al [21] and Trazzi et al [12], the values of pH and SOC increased after biochar amendment. The increases in pH, TP, and TN of soil after biochar amendment are most likely due to the effects of biochar [40,41], whereas the increases in AP and AN were due to the interaction between biochar and soil [15].…”

“…A relatively understudied method of increasing the efficiency of P fertilization in black soil involves soil amendment using biochar. Biochar is an important bio-resource that is produced by pyrolysis under limited air supply [11,12]. Because of the high physical and chemical capacity of biochar, it has been used as a potential soil-amending agent for improving soil P availability by reducing soil P leaching [13] and increasing crop productivity [14].…”

Substantial soil phosphorus (P) losses often occur in the northern temperate regions owing to soil freeze-thaw cycles (FTCs). Presumably, biochar amendment is an efficient method of conserving P and sustaining agricultural production in the black soil region of northeast China. However, how biochar interacts with FTCs to affect soil P adsorption and desorption is unclear. A simulated laboratory FTC experiment was conducted on untreated and biochar-amended soil with varying moisture content to assess their effects on P adsorption and desorption. Soil P adsorption and desorption values were fitted with Langmuir and Freundlich isotherms to determine the interaction of the frequency of FTCs with moisture content and biochar amendment. Higher soil moisture content increased soil P adsorption, whereas biochar amendment mitigated decreased P retention by decreasing soil P adsorption capacity. Biochar amendment significantly increased the desorption ratio (D avg) under all the FTCs. The desorption ratio of soil and biochar-amended soil in saturated moisture content treatment was significantly higher than that of 12 FTCs. The FTCs decreased the P availability of biochar-amended soil by enhancing P desorbability. Our results suggest that biochar amendment in arable black soil should not be conducted during FTCs, particularly during snowmelt.

“…A previous study found positive correlation between pyrolysis temperature and P sorption capacity of biochar (Ngatia et al, 2017), indicating the greater P sorption capacity of high temperature biochar. The main mechanism of P sorption to biochar has been proposed to be the precipitation of phosphate with calcium and magnesium (Karunanithi et al, 2017), and sorption to the large surface area of biochar (Trazzi et al, 2016). Results of a recent study, however, showed WSP700 not to have significant effect on P availability (Bornø et al, 2018).…”

Aims: The aim of this study was to explore interactive effects between quality (types) and quantity (application rates) of biochar as well as of arbuscular mycorrhiza (AM) symbiosis on the growth of potato plants. Methods: A low P sandy loam soil was amended with 0%, 1.5%, or 2.5% (w/w) of either of 4 types of biochar, which were produced from wheat straw pellets (WSP) or miscanthus straw pellets (MSP) pyrolyzed at temperatures of either 550°C or 700°C. Potato plants grown in pots containing the soils or soil biochar mixture were inoculated with or without AM fungus (AMF), Rhizophagus irregularis. The experiment was carried out under fully irrigated semi‐field conditions and plants were harvested 101 days after planting. Results: Application of high temperature biochar decreased growth, biomass and tuber yield of potato plants, while the low temperature biochar had a similar effect on yield as plants grown without biochar amendment. Total biomass of potato plants were decreased with the increasing rate of biochar. Arbuscular mycorrhizal fungus inoculation stimulated the growth of potato plants in all organs, increased tuber biomass significantly in 1.5% MSP700 amended plants, and to a lesser degree for WSP700, MSP550, and WSP550. In addition, plant biomass gain was linearly related to N, P, and K uptake, the ratio of P to N in the leaf of plants indicated that all treatments were mainly P‐limited. A multiple linear regression using P uptake and biochar rate as independent variables explained 91% of the variation in total biomass. The single effect of AMF inoculation, type and rate of biochar affected plant N, P and K uptake similarly. While AMF inoculation significantly increased P uptake in potato plants grown in soil with WSP700 or MSP700 despite of the rate of biochar. In general, application of biochar significantly increased AMF root colonization of potato plants. Conclusions: The application of MSP550 at 1.5% combined with AMF stimulated growth of potato the most. Furthermore, the results indicated that the interactive effect of AMF inoculation, biochar type and application rate on potato growth to a large extent could be explained by effects on plant nutrient uptake.

“…Biomass feedstocks used for the biochar production, the biochar production technology (pyrolytic units), and pyrolysis reaction conditions (temperature and duration of pyrolytic process, special atmosphere) are presented in Table 1. Extensive characterization of the biochars BC1-BC3 and LIM1-LIM3 has been published (Bachmann et al 2016;Trazzi et al 2016). Several biochar samples were prepared under laboratory conditions in a furnace (samples OL1-8).…”

“…In the case of Miscanthus biochar the increase of pyrolysis temperature led to the increase of both the carbon contents (63.6%; 86.3% and 90.4%) and BET surface area (6.39; 81.0 and 244 m 2 g −1 ) for the temperatures 300 °C, 500 °C and 700 °C and pyrolysis time 60 min (Trazzi et al 2016). The selected atomic ratios (i.e., H/C and O/C) sharply decreased, suggesting that with increasing charring temperature, the relative degree of aromaticity (H/C ratio) and polarity (O/C ratio) markedly decreased, which could be attributable to the development of functional groups (Li et al 2013b;Trazzi et al 2016). It has been also observed by other authors that heteroaromatic N-structures are formed during the pyrolysis process; it is expected that N-bound in heterocyclic compounds is chemically stable (Singh et al 2014).…”

Various materials have been extensively investigated to mimic the structures and functions of natural enzymes. We describe the discovery of a new catalytic property in the group of biochar-based carbonaceous materials, which are usually produced during biowaste thermal processing under specific conditions. The tested biochars exhibited peroxidase-like catalytic activity. Biomaterial feedstock, pyrolysis temperature, size of resulting biochar particles or biochar modification (e.g., magnetic particles deposition) influenced the peroxidase-like activity. Catalytic activity was measured with the chromogenic organic substrates N,N-diethyl-p-phenylenediamine (DPD) or 3,3′,5,5′-tetramethylbenzidine (TMB), in the presence of hydrogen peroxide. Magnetic biochar composite was studied as a complementary material, in which the presence of iron oxide particles enhances catalytic activity and enables smart magnetic separation of catalyst even from complex mixtures. The activity of the selected biochar had an optimum at pH 4 and temperature 32 °C; biochar catalyst can be reused ten times without the loss of activity. Using DPD as a substrate, K m values for native wood chip biochar and its magnetic derivative were 220 ± 5 μmol L −1 and 690 ± 80 μmol L −1 , respectively, while V max values were 10.1 ± 0.3 μmol L −1 min −1 and 16.1 ± 0.4 μmol L −1 min −1 , respectively. Biochar catalytic activity enabled the decolorization of crystal violet both in the model solution and the fish pond water containing suspended solids and dissolved organic matter. The observed biochar enzyme mimetic activity can thus find interesting applications in environmental technology for the degradation of selected xenobiotics. In general, this property predestines the low-cost biochar to be a perspective supplement or even substitution of common peroxidases in practical applications.
