Biochar for soil remediation and land reclamation
Land reclamation generally relates to the improvement of soils degraded by human activities, for example construction and certain forms of agriculture. Soil remediation refers to the process of removing, neutralizing or reducing the toxicity of certain compounds, often left by human activities such as mining and industry. Each degraded and/or contaminated site is potentially unique in its chara...
متن کاملProtective Role of Biochar in Different Soil Moisture for Prevent Soil Loss in Laboratory Conditions
The using of soil conditioners to water and soil conservation is essential and also, the effect study of soil moisture on the soil conservation process and its role on changing runoff, soil erosion and sediment yield is necessary for understanding and simulating the hydrologic response of soil. Therefore, the present study was carried with the aim of investigating the effect of biochar with amo...
متن کاملHardwood biochar and manure co-application to a calcareous soil.
Biochar may affect the mineralization rate of labile organic C sources such as manures via microbial community shifts, and subsequently affect nutrient release. In order to ascertain the positive or negative priming effect of biochar on manure, dairy manure (2% by wt.) and a hardwood-based, fast pyrolysis biochar were applied (0%, 1%, 2%, and 10% by wt.) to a calcareous soil. Destructive sampli...
متن کاملDesigner, acidic biochar influences calcareous soil characteristics.
In a proof-of-concept study, an acidic (pH 5.8) biochar was created using a low pyrolysis temperature (350 °C) and steam activation (800 °C) to potentially improve the soil physicochemical status of an eroded calcareous soil. Biochar was added at 0%, 1%, 2%, and 10% (by wt.) and soils were destructively sampled at 1, 2, 3, 4, 5, and 6 month intervals. Soil was analyzed for gravimetric water con...
متن کاملSynergisms between Compost and Biochar for Sustainable Soil Amelioration
Driven by climate change and population growth, increasing human pressure on land forces conversion of natural landscapes to agricultural fields and pastures while simultaneously depleting land currently under agricultural use (Lal, 2009). Consequently, a vicious circle develops; further aggravating climate change, soil degradation, erosion, loss of soil organic matter (SOM) and leaching of nut...
