Can coal be used as a soil amendment?
Best insight from top research papers
Coal can be used as a soil amendment to improve soil properties and support plant growth in reclamation scenarios. Studies have shown that the addition of coal-derived humic substances, such as nano humus, can enhance soil fertility and increase plant biomass. Application of nano humus at the beginning of the growing season has been found to be more effective than splitting into multiple applications . Additionally, the combined use of humic substances and soil biota, such as arbuscular mycorrhizal fungi, has shown synergistic effects in improving soil chemical properties and reducing heavy metal concentrations in coal mine sites . Fly ash, a by-product of coal-fired power plants, can also be used as a soil conditioner when combined with vermicompost. The addition of fly ash and vermicompost has been found to improve soil physical and chemical properties, resulting in better seedling growth and development . Furthermore, fly ash can be carbonated to enhance its stability and sequester CO2, making it a potential soil amendment to improve soil properties . Finally, the addition of short paper fiber to coarse coal refuse has shown potential in supporting vegetation establishment and growth in coal refuse piles .

What plants can be a soil treatment?5 answersPlants that can be used for soil treatment include poplar, peganum harmala, Nitraria tangutorum, red clover, meadow fescue, hybrid ryegrass, borage, and white mustard. These plants have the ability to degrade organic compounds or accumulate heavy metals, making them suitable for phytoremediation. Phytoremediation is a multifaceted technology that utilizes plants for soil decontamination through various mechanisms such as phytostabilization, phytodegradation, phytovolatilisation, and phytoextraction. The effectiveness of plant-based soil treatment depends on the specific contaminants present and the remediation properties of the plant species used. Additionally, the success of soil treatment with plants is influenced by soil characteristics and the presence of rhizosphere communities that can aid in the degradation of contaminants. Overall, phytoremediation offers a practical and cost-effective option for treating contaminated soil and promoting sustainable soil treatment strategies.
What is soil remediation?5 answersSoil remediation is the process of removing or reducing hazardous substances in contaminated soil to eliminate threats to human health and the environment. Various techniques are used for soil remediation, including physicochemical, biological, and thermal methods. These techniques aim to either remove the contaminants from the soil or reduce their concentration to safe levels. Soil remediation can be performed in situ, where the remediation takes place on-site, or ex situ, where the contaminated soil is excavated and treated off-site. Monitoring the effectiveness of soil remediation is crucial, and it can be done by measuring contaminant concentrations or using biological tools to evaluate the ecotoxicological state of the remediated soil. The choice of remediation technique depends on factors such as cost-effectiveness, treatment duration, safety, and efficacy of soil/pollutant treatment. Overall, soil remediation is a critical practice for restoring contaminated soils and ensuring food safety and environmental health.
What are the importance of soil remediation?5 answersSoil remediation is important for managing contaminants in order to protect human health and the environment. It involves identifying contaminated soils, setting remedial objectives, selecting and implementing remedial strategies, and monitoring the results. Contaminant concentrations are commonly measured, but biological tools can also be used to evaluate the ecotoxicological state of the soil. Various in situ and ex situ remediation techniques have been developed to reduce the risk posed by soil and water contamination. These techniques include physicochemical, biological, and thermal methods. Soil remediation methods aim to reduce the content of organic pollutants in the soil, improve its physical and chemical properties, and enhance its adsorbability of organic pollutants. Soil remediation is crucial for restoring soil quality, improving crop yield, and creating a sustainable underground microecosystem.
How does the soil amendments affect root morphology?4 answersSoil amendments have been found to have a significant impact on root morphology. The addition of straw and biochar to the soil resulted in increased root lengths, surface areas, volumes, and mean root diameters. Topsoil amendments such as mycorrhizae, biochar, compost, and manure also influenced root-associated fungal communities and growth. Basidiomycota preferentially grew in certain amendments, such as biochar and compost, while Populus balsamifera roots were associated with a high diversity of Ascomycota. In the case of Spondias tuberosa, different soil amendments affected root growth differently, with manure having a negative impact on fine root dry matter, while clay, biochar, and mineral fertilization did not significantly affect root growth. Organic amendments, such as compost from grape pomace and humic extract, were found to stimulate root development in table grape plants and improve soil quality. Additionally, the use of neem leaf compost as a soil amendment decreased the number of root knots in cowpea plants.
How does the use of compost improve soil ?1 answersCompost improves soil by enhancing its physiochemical and biological properties, such as reducing bulk density, improving water holding capacity, and increasing porosity. It also increases the accumulation of nutrients in the soil, leading to improved soil fertility. The addition of compost to soil helps in the retention of soil organic matter, which benefits the soil and plant health. Compost also aids in the decomposition of biodegradable waste, such as crop residues and kitchen waste, thereby improving the organic matter content in the soil. Furthermore, the use of compost can mitigate the negative effects of urban soil compaction caused by construction activities, resulting in improved infiltration, reduced runoff, and less soil loss. Overall, the use of compost in soil contributes to better soil quality, nutrient cycling, water retention, and reduced soil compaction, ultimately leading to increased crop productivity.
