“…The main peak in response to the turning point for rapid weight loss appeared at 380 and 335°C for PB and MPB respectively. This trend is contrary to that of the magnesium oxide, clay, and hematite modified biochars Yao et al, 2013Yao et al, , 2014, where modified biochars have higher thermal stability than pristine biochar. This may be related to the transition of Mn-oxides during heating process in air atmosphere.…”

“…Similar results were found by Prapagdee and Tawinteung (2017), who reported no significant difference of P content in green bean parts at all BC treatments. Biochar can be a potential P source and some BC can also adsorb P efficiently from solutions (Peng et al 2012, Yao et al 2013. They suggested that BC could play a role in retaining P applied as fertilizer.…”

Zemanová V., Břendová K., Pavlíková D., Kubátová P., Tlustoš P. (2017): Effect of biochar application on the content of nutrients (Ca, Fe, K, Mg, Na, P) and amino acids in subsequently growing spinach and mustard. Plant Soil Environ., 63: 322-327.The objective of this study was to assess the effect of biochar on growth and metabolism of spinach (Spinacia oleracea L.) and mustard (Sinapis alba L.) planted in crop rotation: spinach (spring)-mustard-spinach (autumn). The impact of biochar soil application (5% per mass of soil) on the availability of Ca, Fe, K, Mg, Na and P to plants as well as the content of free proline and total amino acids contents were evaluated at degraded Chernozem soil. The results showed that biochar soil addition significantly increased spinach growth by 102% and 353% in spring and autumn, respectively. Biochar limited plant content of Ca, Mg and Na, however K content increased in all plants. Inconsistent effect was determined for Fe and P content in plants biomass. Total content of free amino acids was higher in plants harvested at amended treatments, except autumn spinach. Biochar increased proline content in all plants in comparison to control. The highest increase was obtained in mustard -by 186%. The results showed a more sensitive reaction of mustard to biochar application than spinach.

Proline (Pro) is specific free AA which is involved in stress metabolism and tolerance of plants (Pavlíková et al. 2014). Our study aimed to compare the ability of spinach and mustard accumulation of nutrients and amino acids as a response to biochar application to soil. MATERIAL AND METHODSExperimental design and soil characteristics. The experiment was conducted at greenhouse controlled conditions. Spinach (Spinacia oleracea L.) and mustard (Sinapis alba L.) were chosen as experimental plants, while the crop rotation was spinach-mustard-spinach. Firstly, spinach was sown in March and harvested after 64 days. Mustard was sown in May and harvested after 35 days. Late spinach was sown in August, harvested after 64 days. Biomass of both spinaches was sampled once during vegetation, after 42 days. Modal Chernozem soil (2.5 kg; Prague-Suchdol, Czech Republic; pH KCl = 7.2, cation exchange capacity (CEC) = 258 mmol + /kg, C org = 1.83%, available content of elements: Ca = 6754 mg/kg; K = 233 mg/kg; Fe = 153 mg/kg, Mg = 191 mg/kg; P = 74 mg/kg) was uniquely fertilized with 0.1 g N, 0.16 g P and 0.4 g K per 1 kg of soil (applied in the form of NH 4 NO 3 and K 2 HPO 4 ), only at the beginning of the experiment. The experiment consists of 2 treatments: (i) control (without BC) and (ii) 5% of the applied BC from total mass of soil (BC 5%) thoroughly mixed with soil volume.Biochar characteristics. Detailed biochar properties were described in Břendová et al. (2016). Bioc...

Biochar simply is the material produced when biomass undergoes any chemical processes under the conditions of pyrolysis. The variety of biomasses, including wood waste, agricultural crop leftover, organic waste, animal manure, and forestry residues, have been considered as raw material to produce biochar. Biochar is widely used for generation of heat and power and an addition to soils, in which it serves as a fertilizer and carbon sequestration agent. Also in the form of being activated, it finds significant role for various adsorption applications. The most beneficial use of a given char depends on its physical and chemical characteristics, even though the relationship of char properties to these applications is not well defined. Various widely used modern analytical techniques, which are applicable and crucial for biochar characterization, have been reviewed in the present work, such as solid state nuclear magnetic resonance spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy, X-rays photoelectron spectroscopy, X-rays diffraction, thermogravimetric analysis, near edge X-rays absorption fine structure spectroscopy, and gas chromatography-mass spectroscopy. Utilization of these modern techniques provides the quantitative as well as qualitative information, i.e., determining the sizes, shapes, and physicochemical characteristics of biochar, which is reliable to track changes in the carbon arrangement over reaction time and temperature, and will be useful for efficient production of biochar and application. It provides the useful information for the researchers in this area and is beneficial not only for the effective biochar production, but also for potential utilization/application, and not only for environment but also for agriculture.
