Applying Biochar and Mineral Amendments to Remediate the Chemical Properties of a Saline-Sodic Soil
The present study was intended to improve the chemical properties of a saline-sodic soil using the individual application of alfalfa residue and two biochars produced from sugarcane bagasse and walnut shell, at the weighting ratio of 5%; their concomitant application with gypsum, aluminum sulfate and the mixture of these two chemical amendments was considered. The experiment was conducted in th...
متن کاملEffects of biochar amendment on soil aggregates and hydraulic properties
The aim of this study was to investigate the effects of biochar amendment on soil aggregate formation and stability, and soil hydraulic properties. Biochar produced from dairy manure was added to two different soils (a silty clay and a sandy loam soil) at a ratio of 2% (w/w in dry weight basis). Incubation experiments were conducted within a 90-d period with the soils (the controls) and the soi...
متن کاملBiochar: Effects on Crop Productivity and Soil Properties
World food security is under challenge to a great extent due to effects of climate change, continued population growth and resource-depleting practices on agriculture (IAASTD, 2009). Presently poor farmers use either organic manure or inorganic fertilizers (Mando et al., 2005; Topoliantz et al., 2005) for maintaining soil fertility as they cannot afford to apply fertilizers as a nutrient source...
متن کاملThe effects of biochar on wetland and agricultural soil carbon and nitrogen emissions in North Carolina
Executive Summary Biochar is an increasingly popular topic in environmental management due to its potential effects on several ecosystem functions. Specifically, biochar has been linked to significant reductions in greenhouse gas emissions, including nitrous oxide, carbon dioxide and methane when used as a soil amendment. It has also been suggested as a long term mechanism to sequester carbon i...
متن کاملBiochar Impacts on Soil Physical Properties and Greenhouse Gas Emissions
Biochar, a co-product of a controlled pyrolysis process, can be used as a tool for sequestering C in soil to offset greenhouse gas (GHG) emissions, and as a soil amendment. Whereas the impacts of biochar application on soil chemical properties are widely known, the research information on soil physical properties is scarce. The objectives of this review are to (i) synthesize available data on s...
