Abstract Chinese hickory (Carya cathayensis Sarg.) is an important economic forest in Southeastern China. A large amount of hickory husk waste is generated every year but with a low proportion of returning. Meanwhile, intensive management has resulted in soil degradation of Chinese hickory plantations. This study aims to investigate the effects of three Chinese hickory husk returning modes on soil amendment, including soil acidity, soil nutrition, and microbial community. The field experiment carried out four treatments: control (CK), hickory husk mulching (HM), hickory husk biochar (BC), and hickory husk organic fertilizer (OF). The phospholipid fatty acid (PLFA) biomarker method was employed… More >

Abstract The toxic dyestuffs from printing and dyeing wastewater have caused serious damages to the ecological environment, thus exploring effective methods to remove them having become a key topic. Here, a series of biochar samples were synthesized form kenaf to adsorb methylene blue (MB), which was acted as the dye representative for the test of adsorption capacity due to the presence of abundant double bond and aromatic heterocyclic ring. By tuning the raw materials and pyrolysis temperature, a super adsorption capacity about 164.21 mg·g^–1 was obtained over the biochar that pyrolyzed at 700°C with the kenaf fiber as raw material. Through… More >

Abstract In this study, the magnetic wakame biochar/Ni composites were prepared with three activating reagents of H₃PO₄, ZnCl₂ and KOH by one-step pyrolysis activation, characterized by BET, SEM, TEM, FI-IR, XRD, Raman, and elemental analyzer, and their adsorption performance for diesel were also analyzed. The results showed that wakame biochar/Ni composites had larger specific surface area, abundant porous structure, and various reactive groups, rendering its enhancement of adsorption efficiency. The adsorption experiments indicated that the maximum adsorption capacities for diesel using WBPA 0.5, WBHZ 0.5 and WBPH 0.5 were 4.11, 8.83, and 13.47 g/g, respectively. The Langmuir model was more suitable… More >

Abstract Soil amendments containing carbonized materials increase the soil carbon reservoir, influence plant productivity, and, ultimately, help to clean the environment. There is data on the effect of such additions on soil physicochemical properties or plant growth, but few studies have focused on how these carbonized materials are distributed by termite species in the soil ecosystem. It is the first comprehensive study of the transportation of biochar (BC) by termite species under tropical environmental conditions in Pakistan. The present study was carried out to test the hypothesis that if termite species I) were involved in the distribution of biochar particles II)… More >

Abstract Due to the unpredictable climate change, drought stress is being considered as one of the major threats to crop production. Wheat (Triticum aestivum L. cv. BARI Gom-26) being a dry season crop frequently faces scarcity of water and results in a lower yield. Therefore, this experiment aims to explore the role of different organic amendments (OAs) in mitigating drought stress-induced damage. The pot experiment consisted of different organic amendments viz. compost, vermicompost and poultry manure @0.09 kg m⁻² soil, biochar @2.5% w/w soil and chitosan @1% w/w soil which was imposed on the plants grown under both well-watered and drought… More >

Abstract In the era of serious greenhouse gas emission and energy shortage, it is necessary to use solid waste to prepare new renewable materials. In this work, the potential application of reed straw and electric furnace dust was explored. Firstly, magnetic carbon carrier (EFD&C) was prepared by high temperature calcination, and then magnetic carbon catalyst (SM@EFD&C) was prepared by activation of sodium methoxide. The catalyst was used to prepare biodiesel by transesterification reaction to test its activity and stability. Reed biochar, EFD&C and SM@EFD&C were detected by Diffraction of X-rays (XRD), Fourier transform infrared (FT-IR), Inductively coupled plasma (ICP), Scanning electron… More > Graphic Abstract

Abstract Soil degradation threatens the forest sustainable productivity, particularly in afforestation system. Biochar derived from agroforestry waste or biomass can potentially improve the degraded forest soil and promote the tree growth. To expand the application of biochar for forestry productivity improvement, we here reviewed the effects and the underlying mechanisms of biochar on the degraded forest soil and tree growth. Totally 96 studies that conducted from pot to field investigations in China were summarized. The result suggested that biochar generally exerted positive effects on restoration of degraded forest soil such as that with compaction, acidification or soil erosion, which are mainly… More >

Abstract The emissions of two greenhouse gases (GHG), carbon dioxide (CO2) and nitrous oxide (N2O), from six substrates with different carbonaceous content were compared in short and long-term incubation experiments. Three natural soils and three artificial chars were mixed with carbon (C) poor soil (Cambisol) to simulate real conditions after application of char to farmland. The natural soils were a Cambisol, an Anthrosol and a Histosol with C contents of 1.3%, 4.4% and 13.2%, respectively. The three chars produced through thermal conversion of wood chips by hydrothermal carbonisation (HTC), fluidized bed gasification and pyrolysis had C contents of 56.9%, 75.4% and… More >

Abstract Biomass is a carbon-neutral renewable energy resource. Biochar produced from biomass pyrolysis exhibits preferable characteristics and potential for fossil fuel substitution. For time- and cost-saving, it is vital to establish predictive models to predict biochar properties. However, limited studies focused on the accurate prediction of HHV of biochar by using proximate and ultimate analysis results of various biochar. Therefore, the multi-linear regression (MLR) and the machine learning (ML) models were developed to predict the measured HHV of biochar from the experiment data of this study. In detail, 52 types of biochars were produced by pyrolysis from rice straw, pig manure,… More >
