“…Particularly organic matter and Humic + Fulvic Acid contained in coal or coal waste contribute to soil quality and plant growth. Obtaining better results in the prepared mixtures than the reference mixture is due to this organic matter and Humic + Fulvic Acid in the coal content (Song and Lee, 2010;Peña et al, 2015;Ultra et al, 2022;Bai et al, 2023;Feng et al, 2023;Jayapal et al, 2023;Yin et al, 2023).…”

In this study, the usability of the mixtures consisting of lignite coal taken from Tekirdag region and marble and travertine wastes taken from the marble factory in Gumushane region in local bean (Kelkit) cultivation was researched. First, control samples were created using only humus soil without coal, marble, or travertine dust. Then, for each coal or coal waste, coal/coal waste—waste marble dust and coal/coal waste—travertine dust mixtures were formed. These mixtures were obtained by mixing 25%, 50%, 75%, and 100% by weight of coal and 25%, 50%, and 75% by weight of marble and travertine dust. Afterwards, local beans were planted in these mixtures and their development was followed under laboratory conditions. Additionally, temperature and humidity values were recorded at certain intervals, pH and heavy metal analysis measurements were made on the mixtures before and after bean planting, the height and leaf measurement of the beans grown and the number of beans grown in these beans were also followed, and chlorophyll analysis was performed on the bean plants grown in these mixtures. As a result, 50% Coal-3D + 50% Travertine mixture had the maximum length increase, that 25% Coal Waste (Powder)-K3 + 75% Marble mixture had the highest number of beans, and that 50% Coal Waste -AK + 50% Marble mixture had the maximum leaf formation. In these mixtures, maximum 12 beans were grown and maximum 93 leaves were formed. Also, the bean plant was grown in all mixtures. The chlorophyll contents were at least as much as the values of the beans grown only in soil. However, heavy metal values do not exceed the permissible limit values in soil.

Crop requires proper plant nutrition; one of the most important factors governing plant growth and development is the integrated supply of micronutrients and macronutrients in adequate amounts and appropriate proportions; although micronutrients are required in minute quantities, they play an important role in plant growth. Micronutrients must be used wisely in crop production to ensure the optimum output of high-quality products. Plant metabolism, nutrition management, chlorophyll synthesis, reproductive growth, flower retention, and fruit and seed development are all performed by micronutrients. Boron, chlorine, copper, iron, zinc, manganese, molybdenum, and nickel are micronutrients that are required by all higher plants. Chlorine, copper, iron, and manganese are engaged in diverse photosynthetic activities, whereas zinc, copper, iron, and manganese are involved in various metabolic processes. Molybdenum is exclusively found in nitrate reductase. Boron is related with glucose metabolism, plant reproduction, photosynthesis, and enzymatic activity. The review focuses on the primary roles of micronutrients in crop development and gives an overview of recent research discoveries linked to the role of micronutrients in plants, helping to improve knowledge of their importance.

“…The relevant research results show that these topsoil substitutes can effectively improve the soil, improve the crop biomass [9][10][11], reduce the land occupation of solid waste in the mining area and environmental pollution, and achieve the goal of "treating waste with waste". In China, most solid wastes are used as soil improvement materials to improve the physical and chemical properties of the soil [12,13], so as to increase soil nutrients, improve soil fertility, and achieve resource recycling [14][15][16][17][18][19].…”

Aiming at the problem that coal gasification coarse slag is seldom used in soil improvement at present, this study takes the waste dump of Hongshaquan No.1 open-pit mine in Zhundong, Xinjiang, as the research object, uses the local coal gasification coarse slag to prepare coal-based soil improver to improve the soil in the study area, and compares it with the improvement effect based on fly ash and domestic sludge to explore the soil improvement effect of different solid wastes. The improvement experiment results show that, in terms of soil particle size, the addition of fly ash and domestic sludge can increase the soil clay content and reduce the sand content, but the effect of coal gasification coarse slag on soil particle size composition is not obvious. In terms of soil nutrients, fly ash will reduce the content of soil organic matter, available potassium and alkali hydrolyzable nitrogen, but increase the content of available phosphorus. Coal gasification coarse residue will increase the content of soil organic matter and available phosphorus, but it has little effect on the content of available potassium and alkali hydrolyzable nitrogen. Domestic sludge will improve the contents of soil organic matter, available potassium, alkali hydrolyzable nitrogen and available phosphorus. In terms of soil pH, fly ash and coal gasification coarse slag will increase soil alkalinity, and domestic sludge will reduce soil alkalinity. The results of the pot experiment in the field showed that the coal gasification coarse slag had the best improvement effect, followed by domestic sludge and finally fly ash. By clarifying the effect of improved materials, this study can better use coal-based solid waste resources in the field of ecological restoration of degraded soil, so as to provide a scientific basis for the ecological reconstruction and pollution restoration of local arid ecologically fragile saline alkali land.
