Opis:
The agricultural and environmental sectors are plagued with challenges. In agriculture, soil infertility and the subsequent quagmire of poor crop yield, has always been a major problem that limits worldwide agricultural productivity. Major environmental concerns, including Climate Change and Soil Pollution, are receiving continual attention from key stakeholders. Efforts are hence being directed at curtailing or mitigating the devastative consequences of these man-made ‘monsters’. Recently, agricultural and environmental research reveals biochar to be a veritable technology that could be used to deal with some of these concerns. Biochar has the ability to have impact upon important soil properties, such as the raising of soil pH and water holding capacity, the attraction of beneficial fungi and microbes, improvement of cation exchange capacity (CEC), induce high carbon sequestration ability and nutrient retention capacity. Moreover, its large surface area makes it a potential remedy to several identified challenges. This review, therefore, critically highlights the importance of biochar, as well as the various ways of harnessing biochar technology towards global food security and environmental sustainability.

Opis:
A study was carried out at the Department of Horticulture, KNUST from 8th January, 2017 to 17th March, 2017 to determine the best propagating medium for Ixora coccinea and Ficus pumila. The design was a Complete Randomized Design with four treatments replicated three times. The treatments were; topsoil only, biochar only, mixture of topsoil and biochar (1:1) and mixture of topsoil and biochar (2:1) . The study revealed that the treatment with the mixture of topsoil and biochar (2:1) was the best medium, in terms of physical and chemical properties and produced the highest number of leaves and rooted cuttings in Ficus pumila. Topsoil only had highest number of leaves and roots for Ixora coccinea. The biochar medium started rooting earlier for Ficus pumila at 2 weeks and recorded the highest number of leaves, while that of Ixora coccinea rooted at the fourth week towards the fifth week. The study concluded that mixture of topsoil and biochar (2:1) could be used for propagating difficult to root ornamental plants whiles Biochar only could also be used to propagate Ficus pumila.

Opis:
In this study, comparative potential effects of commercial activated carbon (CAC) and plantain peel-derived biochar (PPBC) of different particle sizes and dosage to stimulate petroleum hydrocarbon biodegradation in soil were investigated. Microcosms containing soil were spiked with weathered Bonny light crude oil (WBLCO) (10% w/w) and amended with different particle sizes (0.02, 0.07 and 0.48 mm) and dosage (20, 30 and 40 g) of CAC and PPBC, respectively. The bioremediation experiments were carried out for a period of 28 days under laboratory conditions. The results showed that there was a positive relationship between the rate of petroleum hydrocarbons reduction and presence of the CAC and PPBC in crude oil contaminated soil microcosms. The WBLCO biodegradation data fitted well to the first-order kinetic model. The model revealed that WBLCO contaminated-soil microcosms amended with CAC and PPBC had higher biodegradation rate constants (k) as well as lower half-life times (t1/2) than unamended soil (natural attenuation) remediation system. The rate constants increased while half-life times decreased with decreased particle size and increased dosage of amendment agents. ANOVA statistical analysis revealed that WBLCO biodegradation in soil was significantly (p = 0.05) influenced by the addition of CAC and biochar amendment agents, respectively. However, Tukey’s post hoc test (at p = 0.05) showed that there was no significant difference in the bioremediation efficiency of CAC and PPBC. Thus, amendment of soils with biochar has the potential to be an inexpensive, efficient, environmentally friendly and relatively novel strategy to mitigate organic compound-contaminated soil.

This study aimed to investigate the effect of alternate furrow irrigation accompanied by biochar application within different cropping patterns on soil respiration and root traits such as root dry weight and root volume associated with the dry matter yield of sorghum (Sorghum bicolor L.) over a twoyear period (2017 – 2018). The treatments consisted of three irrigation methods, which included every furrow irrigation, fixed furrow irrigation and alternate furrow irrigation and two cropping patterns including one-row, two-rows and three levels of biochar application including 0, 6 and 12 t ha-1. Different irrigation levels had a significant effect on root morphological indices, soil respiration, and the dry matter of forage yield. Biochar application showed a significant influence on soil respiration, as the highest soil respiration was observed in the B2 and B1 treatments (0.173 and 0.171 μmol C g-1 soil h-1, respectively), in contrast, the least was observed in the control treatment B0 (0.168 μmol C g-1 soil h-1). Biochar application had a positive effect on root dry weight, root volume and dry matter yield due to the prevention of severe moisture loss and further yield loss.

The addition of biochar is often proposed to increase agricultural soil quality and crop yield, while at the same time sequestering carbon from the atmosphere to help mitigate global climate change. In this research, the pore-size distribution, and saturated hydraulic conductivity of sandy loam and clay loam soils amended with varying dosages (0-10% dry basis) and two different particle sizes (0.5-420 μm (PS1) or 421-841 μm (PS2)) of wood-derived biochar were investigated under compacted conditions (5, 10, or 15 standard Proctor rammer blows (5B, 10B, or 15B, respectively)). In the 5B compacted SL (SL-5B) soil, the volume of the soil fissures and transmission pores decreased, while the volume of the storage pores (SP) increased with increasing wood-derived biochar dosage. 23.1±0.9% of the volume of the 5B compacted clay loam (CL-5B) are storage pores, this value increased to 27.4±2.0% upon amendment with 10% PS1. The saturated hydraulic conductivity of the sandy loam-5B soil amended with 10% PS1 decreased from 6.8±0.3 to 0.80±0.03 mm h-1. The sandy loam farmland C emissions decreased by 0.071 tC ha-1 y-1, whereas CL farmland C emissions decreased by 0.091 tC ha-1 y-1.

Biochar is proven to enhance soil fertility and increase crop productivity. Given that the influence of biochar on soil compaction remains unclear, selected physico-mechanical properties of soil amended with wood-derived biochar were assessed. For unamended silt loam, the bulk density, maximum bulk density, optimum moisture content, plastic limit, liquid limit, and plasticity index were 1.05 Mg m-3, 1.69 Mg m-3, 16.55, 17.1, 29.3, and 12.2%, respectively. The penetration resistance and shear strength of the unamended silt loam compacted in the standard compaction Proctor mold and at its optimum moisture content were 1800 kPa and 850 kPa, respectively. Results from amending the silt loam with 10% particle size ranges (0.5-212 μm) led to relative decreases of 18.1, 17.75, 66.66, and 97.4% in bulk density, maximum bulk density, penetration resistance, and shear strength, respectively; a 26.8% relative increase in optimum moisture content; along with absolute increases in plastic limit, liquid limit, and plasticity index of 5.3, 13.7, and 8.4%, respectively. While the biochar-amended silt loam soil was more susceptible to compaction, however, soil mechanical impedance enhanced.

Opis:
It was found that date seeds are suitable for biochar production due to their low moisture content 8.92%, low ash yield 1.05%, and high organic matter content 78.3%. The biochar was produced by pyrolysis at 350, 450 and 550°C. The effect of pyrolysis temperature on the physicochemical characteristics of biochar was investigated. It was found that the porosity, water holding capacity, ash content, pH, organic matter, fixed carbon, and the elemental content of Na, K, Ca, Mg, Fe, Mn, P, Zn, Ba, Cr, Cu, Ni, Pb, Ti, and V were increased along with pyrolysis temperature. Meanwhile, the biochar yield, bulk density, and the total content of N and S were decreased. The biochar was tested as a sustainable adsorbent to investigate the adsorption of Cd from contaminated water. The adsorption isotherms of Cd on biochar were determined based on Langmuir equation. The maximum adsorption of Cd at 25°C and pH 7 were 667, 714, and 833 mg/kg for the biochars produced at 350, 450, and 550°C, respectively. On the basis of the physicochemical characteristics of the biochar and the findings from Langmuir equation that showed the biochar produced at 550°C has the highest adsorption capacity for Cd, the desorption/adsorption experiment was carried out using the biochar produced at 550°C. The adsorption of Cd by biochar was directly proportional to the Cd concentrations. It was increased from 0.009 mmol/0.5g at 0.01 mmol Cd to 0.12 mmol/0.5g at 0.2 mmol Cd concentration. The desorption of Cd from biochar was increased proportionally to cadmium concentrations from 0.01 to 0.05 mmol and became constant above 0.05 mmol, regardless of the increment of cadmium concentrations. High retention potential for the cadmium that adsorbed within the biochar was proven in this study with desorption/adsorption percentage of 16%. These findings provide a successful example of date seeds converting into the sustainable adsorbent for Cd removal from aquatic environment to achieve the conception of eco-friendly production, which should be studied further.

Opis:
The date seeds (DS) biochar produced at 550°C was found to be appropriate for remediation of metal-contaminated water. This was evident in the data, which showed that applying the biochar to Raphanus sp. and Arabidopsis sp. reduced metal stress and toxicity. The LC50 of all tested metals solutions on seed germination was increased significantly (P<0.05) in Raphanus sp. by 10.4, 2.3, 5, 1.8, and 3 folds, respectively, for Cu, Zn, Cd, Pb, and metals combination, and by 5, 3.4, 6, 5.5, and 2.5 folds in Arabidopsis sp. For seedling growth, the DS biochar enhanced the LC50 significantly (P<0.05) of the same metals in Raphanus sp. by 9.6, 9.2, 13.8, 12.1, and 1.6 folds, and in Arabidopsis sp. by 7, 3, 2.3, 2.9, and 2.7 folds, respectively. The LC of all metals was increased by 1.5 to 8 times and 1.5 to 12 times, respectively, for the seed germination and seedling growth of Raphanus sp. and Arabidopsis sp. Both plants were able to grow shoots at higher metal concentrations when the DS biochar was employed, as compared to the case when no DS biochar was utilized. In terms of shoot length, similar results were achieved, with the DS biochar application significantly enhancing shoot length (P<0.05), as compared to the case when no biochar was applied. Despite the fact that Arabidopsis sp. was more sensitive to metals than Raphanus sp., both plants raised their RGR and TI and reduced their phytotoxicity values in all metals following the DS biochar application, and sprouted at higher metal concentrations than before. These findings introduce a successful eco-friendly adsorbent for metal removal from aquatic environments, paving the way for more investigations.

Sorption studies were carried out to investigate removal of 2.4-dichlorophenol (2.4-DCP) from aqueous solution in a fluidized bed by two types of adsorbent mixtures: BC (Bamboo char plus Calcium sulphate), and HBC (Hydroxyapatite plus Bamboo char plus Calcium sulphate); both manufactured in ball shape. The main material bamboo char was characterized by FTIR, DTA and SEM. The adsorption experiments were conducted in a fluidized bed circulation column. Adsorption, isotherms and kinetic studies were established under 180 min operating process time, at differentinitial 2.4-DCP solution concentrations ranging from 5–10 mg/L, and at different flow rates ranging from 0.25–0.75 L/min. The data obtained fitted well for both the Langmuir and Freundlich isotherm models; indicating favorable condition of monolayer adsorption. The kinetics of both adsorbents complies with the pseudo second-order kinetic model. BC was proven a new effective composite and low cost adsorbent which can be applied in the field of wastewater treatment, and it can also play an important role in industry water treatment.

Opis:
To develop the sorption efficiency of heavy metals: Cd(II), Co(II), Zn(II) and Pb(II) ions the biochar was modified by chitosan, FeSO4 and NaBH4. The morphology, physical structure and chemical composition of the biochar based sorbents were characterized by the scanning electron miscroscopy method, N2 adsorption and desorption isotherms, X-ray diffractometry as well as the Fourier transform infrared spectroscopywith the attenuated total reflectance analyses. The research of M(II) ions sorption was carried out as a function of pH (2-6), interaction time (0-360 minutes) and temperature (293, 313, 333 K). The maximum sorption was obtained by the ChBC for Zn(II) ions - 19.23 mg/g and for MBC-Pb(II) - 19.11 mg/g. Different kinetic models as well as both isotherm and thermodynamic equations were used the sorption data modelling. For Cd(II), Co(II) and Zn(II) ions the nonlinear regression of the Elovich equation gave the best fit for the experimental data. On the other hand, for Pb(II) ions, the nonlinear forms of pseudo first order and pseudo second order show a better match. The value of the correlation coefficient >0.960 determined from the Freundlich isotherm model is the highest suggesting a good fit to the experimental data. The thermodynamic parameters: ΔG°, ΔH° and ΔS° were listed and indicated that the process is spontaneous and endothermic in nature. The desorption efficiency was determined with the use of nitric, hydrochloric and sulfuric acids and the largest desorption yield for Pb(II)-ChBC equal 99.5 % was gained applying HNO3.

Opis:
Adsorption is one of the basic surface phenomena involving saturation of the adsorbent surface with adsorbate molecules located near the adsorbent-adsorbate interface. The processes that are accompanied by the accumulation of adsorbate molecules on the surface are different from absorption, which is related to absorbing molecules into the whole mass and requires diffusion into the interior. If both processes can occur simultaneously, this phenomenon is called sorption. The aim of the present study was to characterize the sorption properties of selected sorbents and to assess the possibility of their application to support the treatment of coking wastewater from ammonium nitrogen, phenol, and TOC. The scope of the study included the examinations of sorption properties of selected sorbents (coal dust, coke dust, biochar), physicochemical tests of coking wastewater after biological treatment, as well as the examinations aimed to determine the dose of adsorbents and time needed to establish the equilibrium state of the process. The results obtained were analyzed for the effect of dose and contact time on the pollutant removal efficiency. The literature describes the efficiency of ammonium nitrogen removal from wastewater using chemical processes. However, there is a lack of studies on the removal of ammonium nitrogen, phenol, and TOC from industrial (coking) wastewater. The conducted study aimed to develop an alternative solution to the currently used conventional methods of removing high concentrations of pollutants from wastewater.

This paper presents an overview of the literature research on the benefits of biocarbon (biochar) as an important part of sustainable agriculture and carbon farming. The main objective was to familiarise the reader with the literature findings on the effects of biocarbon application on the environment, soil, soil organic mater, soil microorganisms, and impact on crop yields. On the basis of the research presented, it can be concluded that the incorporation of biocarbon into the soil generally has a positive effect on soil fertility, but that proper application is required (mainly its application together with fertilization). The quality, properties, and agricultural usefulness of the biochar depend on the raw material that has been subjected to the pyrolysis process, as well as the temperature and time of. The findings of the paper are based on the literature review on the subject.

Opis:
The lack of organic matter content in deteriorated soils in drought stricken areas is a serious problem for vegetation cover. The use of organic amendments like biochar and compost to agricultural soils could be a good remedy for poor soil, water deficiency and plants growth. The comparative analysis of the effects of biochar produced from argan shells, compost and their mixture on the growth of quinoa (Chenopodium quinoa), sugar beet (Beta vulgaris) and alfalfa (Medicago sativa) was the main objective of this research. It was assumed that the addition of biochar mixed with compost could enhance soil fertility and then improve crop productivity of plants. For this purpose, three treatments (2%, 4% and 6%) of biochar (B), compost (C) and biochar–compost (B–C) mixture were applied to soil. The samples for different treatments were collected, incubated and then analyzed. In order to evaluate the plant growth, the greenhouse experiments were conducted for three months in the pots filled with untreated and treated soils. The results showed that the addition of biochar and compost to soil increased pH, electrical conductivity, exchangeable cations, total nitrogen, phosphorus, total organic matter and cation exchange capacity. A significant improvement of the biomass of plants has been observed when applying a mixture of biochar and compost at 6% for quinoa and sugar beet and at 4% for alfalfa. According to the obtained results, mixing argan biochar with compost has a positive impact on soil nutrients and growth of plants.

Opis:
The samples of pyrolytic carbon from Burgau Waste Pyrolysis Plant (Germany) produced by pyrolysis of municipal, industrial and special waste were monitored in terms of ecotoxicity. Collembola (springtails) were selected for reproductive bioassay. After 28 days’ incubation of juveniles, the value of EC50 was determined for selected metals. The study indicates the lowest sensitivity of Folsomia candida to iron (1.689 mg/kg dry matter correspond to EC50). The relative sensitivity for other metals can be expressed in form of a series: Fe < Zn = Cu < Pb < Mn < Ni = Cd. The highest sensitivity was found for cadmium (1.2 mg/kg dry matter). Pyrolytic carbon from MPA Burgau contains high concentrations of chlorides, which cause inhibition of reproduction of Folsomia candida and therefore represent a limiting factor for determination of ecotoxicity of heavy metals in Folsomia candida. The index of acute toxicity EC50 was obtained for concentration of 500 mg/kg chlorides in dry matter.
Próbki karbonizatu z Burgau Waste Pyrolysis Plant (Niemcy) wytwarzanego podczas pirolizy odpadów komunalnych, przemysłowych i specjalnych były badane pod kątem ekotoksyczności. Do badań biologicznych rozmnażania wybrano Collembola (skoczogonki). Po 28 dniach inkubacji młodych, ustalono wartość EC50 dla wybranych metali. Badanie wykazało najniższą wrażliwość Folsomia candida na żelazo (1,689 mg/kg suchej masy w stosunku do EC50). Relatywna wrażliwość na inne metale może zostać zaprezentowana jako Fe < Zn = Cu < Pb < Mn < Ni = Cd. Najwyższą wrażliwość stwierdzono dla kadmu (1,2 mg/kg suchej masy). Karbonizat z MPA Burgau zawiera wysokie stężenia chlorków, które powodują zahamowanie reprodukcji Folsomia candida a zatem jest ograniczonym wskaźnikiem ekotoksyczności metali ciężkich.

Opis:
Prezentowana praca obejmuje analizę różnych wariantów składników takich jak biowęgiel, bazalt, otręby pszenne i gleby uniwersalnej do opracowania polepszaczy glebowych w celu przetestowania ich w późniejszych badaniach. Do tego celu konieczna była analiza wieloelementowa poszczególnych komponentów. Wstępna analiza wieloelementowa poszczególnych składników wykazała, że są one wysoko wartościowe i mogą być wykorzystane do komponowania składu polepszacza do gleby. Dzięki analizie udowodniono, że żaden z tych dodatków nie przekracza zawartości metali ciężkich rekomendowanych w Rozporządzeniu MRiRW z dnia 18 czerwca 2008 r. (Dz. U. Nr 119, poz. 76). Przeprowadzona analiza wieloelementowa wskazuje na możliwe wykorzystanie poszczególnych składników do przygotowania polepszacza glebowego.
The presented work includes the analysis of different variants of ingredients such as biochar, basalt, wheat bran and universal soil for the development of soil improvers to be tested in later studies. For this purpose, a multi-element analysis of individual components was necessary. The preliminary multi-element analysis of individual components showed that they are highly valuable and can be used to compose the soil improver. The analysis proved that none of these additives exceeds the content of heavy metals recommended in the Regulation of the Ministry of Agriculture and Rural Development of June 18, 2008 (Journal of Laws No. 119, item 76). The conducted multi-element analysis indicates the possible use of individual components for the preparation of a soil improver.
