Characteristics of Biochar-Amended Soil Cover for Landfill Gas Mitigation
In this study, biochar-amended soil cover was investigated to enhance reduction of CH4 emissions from landfills. This paper presents physical and chemical characteristics of biochar-amended soils. Specifically, moisture content, organic content, ash content, pH, particle size distribution, Atterberg limits, specific gravity, and permeability tests were conducted with biochar alone, soil alone, ...
متن کاملSwitchgrass biochar affects two aridisols.
The use of biochar has received growing attention because of its ability to improve the physicochemical properties of highly weathered Ultisols and Oxisols, yet very little research has focused on its effects in Aridisols. We investigated the effect of low or high temperature (250 or 500°C) pyrolyzed switchgrass () biochar on two Aridisols. In a pot study, biochar was added at 2% w/w to a Declo...
متن کاملDynamics of bacterial populations in relation to carbon availability in a residue-amended soil
Bacterial response to alteration in C availability is important in understanding the microbial community structure and microbial interactions in soil ecosystems. Population dynamics of oligotrophic and copiotrophic bacteria in relation to soil C availability were examined and relationships between bacterial populations and water-extractable C, buffer-extractable C, mineralizable C or microbial ...
متن کاملCharacterization and Effect of Biochar on Nitrogen and Carbon Dynamics in Soil
In the current study the biochar material was produced by the indigenous pyrolysis of prosopis wood material under high temperature and characterized. The impact of biochar on carbon and nutrient dynamics in soil was examined by conducting a laboratory closed incubation experiment. The biochar produced from prosopis was neutral in pH with an exchangeable acidity of 49 mmol kg. The cation exchan...
متن کاملAtrazine leaching from biochar-amended soils.
The herbicide atrazine is used extensively throughout the United States, and is a widespread groundwater and surface water contaminant. Biochar has been shown to strongly sorb organic compounds and could be used to reduce atrazine leaching. We used lab and field experiments to determine biochar impacts on atrazine leaching under increasingly heterogeneous soil conditions. Application of pine ch...
