“…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...

“…In recent years, biochar production, focused on agricultural residues, has gained increasing interest [1][2][3]. Biochar is a recalcitrant organic compound and better environmental improvement additive, created when biomass (feedstock) is heated to temperatures between 300 and 10008C under low oxygen concentrations [4][5][6].…”

One mechanism by which biochar application enhances soil nutrient availability is through direct nutrients release from biochar. However, factors controlling the release processes are poorly understood. In this study, the effects of pH, biochar to water ratio, temperature, ionic strength, and equilibration time on the release of PO 4 3À , NO 3 À , and Mg 2þ were co-solubilized with increasing soil acidity. To a lesser extent, the recovery of the nutrients was also affected by the ratio of biochar to water: more nutrients were soluble with more water supply. In contrast, the release of Na was not affected by pH while the concentration increased with decreasing biochar to water ratio. Meanwhile, other factors (temperature, ionic strength, and equilibration time) had less effect on nutrient release from biochar. Under the influence of pH, the patterns of NO 3 À and PO 4 3À release from biochar were different: extractable NO 3 À concentration was not affected by the pH but more PO 4 3À was released in strongly acidic conditions.Our data suggested that P was mainly retained in inorganic forms while N was in organic forms in biochar. We conclude that environmental factors have marked influences on nutrients release from biochar.

“…Consequently, the cost of water treatment will be reduced . Eventually, by converting waste into fertilizers and useful materials for water treatment, this practice may create revenues (Huang et al 2010;Peng et al 2012). Apparently it may provide a sustainable, efficient and profit regenerating solution for P management (Kuzma 2011).…”
