Abstract Irmak Yilmaz-Ergun: Impact of biochar and animal manure on some biological and chemical properties of soil-8865-APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 17(4):8865-8876. Abstract. The aim of this study was to show the relationship between tomato plants grown in soil in different doses of animal manure (AM) and biochar (BC) obtained from hazelnut shell with some […]

Abstract Four low-cost organic soil amendments (chicken manure, CM; horse manure, HM; yard water, YW; and sewage sludge, SS) that are generated daily in large amounts, and native bare soil were planted with tomato (Solanum lycopersicum var. Mountain spring) seedlings of 52 days old in raised black plastic-mulch. Each of the 5 treatments was also […]

Abstract Converting swine manure into biochar has increasingly been considered a useful method to reduce heavy metal (HM) availability; however, the associated environmental risks need further exploration. In this study, swine manure was pyrolyzed at diff ;erent temperatures ranging from 200 to 700 °C; this was aimed at studying the effect of temperature on the swine […]

Abstract Biochars derived from animal manures may accumulate potentially toxic metals and cause a potential risk to ecosystem. The synchrotron-based X-ray spectroscopy, sequential fractionation schemes, bioaccessibility extraction and leaching procedure were performed on poultry and swine manurederived biochars (denoted PB and SB, respectively) to evaluate the variance of speciation and activity of Cu and Zn […]

Abstract Livestock-manure-derived biochar is one of major products obtained from the pyrolysis of livestock manure. This study quantitatively assesses the pollution level and ecological risks associated with heavy metals in livestock manure and the biochar produced by its pyrolysis. The geo-accumulation index (GAI) values of heavy metals in livestock manure were significantly decreased (P < 0.05) […]

Abstract The effects of chicken manure biochar (CMB) and chicken manure integrated microbial consortium (CMMC) as co-amendments were assessed on compost maturity and reduction of greenhouse gases and ammonia (NH3) emissions during chicken manure composting. Composting was conducted using six combinations of CMB and CMCC (0 % CMB + 0 % CMMC, 0 % CMB + 10 % CMMC, […]

Abstract Traditional disposal of animal manures and lignocellulosic biomass is restricted by its inefficiency and sluggishness. To advance the carbon management and greenhouse gas mitigation, this review scrutinizes the effect of pyrolysis in promoting the sustainable biomass and manure disposal as well as stimulating the biochar industry development. This review has examined the advancement of pyrolysis of animal manure (AM) […]

Abstract Bioproducts from biomass feedstocks and organic wastes have shown great potential to address challenges across food-energy-water systems. However, bioproducts production is at an early, nascent stage that requires new inventions and cost-reducing approaches to meet market needs. Biochar, a byproduct of the pyrolysis process, derived from nutrient-rich biomass feedstocks (e.g., cattle manure and poultry […]

Abstract Biochar can be fabricated from waste biomass via thermochemical conversion. Here we investigated the production of activated biochar from cow manure via three different approaches, i.e., hydrochar-impregnation (HAC), impregnated biomass pyrolysis (PAC) and one-pot hydrothermal carbonization (HOC). The surface area of HAC, HOC and PAC increased from 81.00, 307.06 and 333.03 m2/g to 637.75, 791.20 and 841.91 m2/g, respectively, with […]

Abstract African balsam (Daniella oliveri) leaves and cow dung are waste materials that are commonly accessible in Africa and can be used to produce biochar by simultaneous thermochemical processing. In this study, biochar was produced in a retort-heated, non-electrically powered, top-lit updraft reactor using the biomass fuel-powered thermochemical conversion of dried cow dung and African […]
