“…3 mg•kg -1 , respectively at 20 and 30% of fly ash content). As reported by Lombard et al [2011] and Yu et al [2019], fly ash from thermal power plants, or ash generated during the recycling of sewage sludge, is treated as a waste containing certain elements useful in agricultural production and can, therefore, be added to the soil to improve some of its physicochemical properties [Wyszkowski et al, 2022]. However, in the ashes, only trace amounts of phosphorus are present in a form that is available to plants [ Gomes et al, 2016].…”

The aim of the research was to assess the quality of organic matter contained in sewage sludge composting products and their co-composting with fly ash and mineral wool. The object of the research were composts produced using stabilized sewage sludge from the municipal sewage treatment plant (SS_1C) and sewage sludge with the addition of 20% (SSF_2C) and 30% (SSF_3C) of fly ash and 5% (SSW_4C) and 10% (SSW_5C) of mineral wool. Selected physicochemical properties, fractional composition of humic compounds, and the degree and rate of humification were determined in compost samples taken after 180 days of composting. The reaction of the evaluated composts was close to optimal for mature composts. Co-composting of sewage sludge with mineral wool and ash increased the sorption capacity in composts compared to SS_1C. Due to the content of available P and Mg, the discussed composts formed the SS_1C>SSF_2C and SSF_3C>SSW_4C and SSW_5C series. However, in terms of available K content: SSF_2C and SSF_3C>SSW_4C and SSW_5C>SS_1C. In the SS_1C compost the organic carbon (TOC) content was slightly higher, but no statistically significant effect of the addition of fly ash and mineral wool on the TOC content in mature composts was confirmed. The addition of ash and mineral wool significantly increased the total nitrogen content. Due to the humification index, the composts formed the series: SSW_4C > SSW_5C > SSF_2C > SS_1C > SSF_3C. The values of the C-KH/C-KF ratio in SS_1C were typical for good quality soils, while in the remaining composts the C-KH/C-KF values were slightly lower. The degree of humification of the assessed composts was characterized by poorly humified organic materials, with the highest values of this indicator found in composts with the addition of mineral wool. The assessed quality indicators of organic matter indicate that the organic matter of composts from sewage sludge with the addition of mineral wool and 100% sludge was of the highest quality.

Applicability of Ash Wastes for Reducing Trace Element Content in Zea mays L. Grown in Eco-Diesel Contaminated Soil

Among the large group of xenobiotics released into the environment, petroleum derivatives are particularly dangerous, especially given continuing industrial development and the rising demand for fuel. As increasing amounts of fly ash and sewage sludge are released, it becomes necessary to explore new methods of reusing these types of waste as reclamation agents or nutrient sources. The present study examined how soil contamination with Eco-Diesel oil (0; 10; 20 cm3 kg−1 soil) affected the trace-element content in the aerial parts of maize. Coal and sludge ashes were used as reclamation agents. Our study revealed that diesel oil strongly affected the trace-element content in the aerial parts of maize. In the non-amended group, Eco-Diesel oil contamination led to higher accumulation of the trace elements in maize (with the exception of Pb and Ni), with Cu and Mn content increasing the most. The ashes incorporated into the soil performed inconsistently as a reclamation agent. Overall, the amendment reduced Mn and Fe in the aerial parts of maize while increasing average Cd and Cu levels. No significant effect was noted for the other elements.

“…According to Gao and DeLuca [57], Hale et al [58], and Saletnik et al [59], it has a positive effect on plant growth and development and increases yield. In the study by Wyszkowski et al [60], coal ash and sewage sludge ash were used as substances to reduce soil contamination with diesel oil. Romdhane et al [19] used willow biomass ash as a soil amendment.…”

Maize can easily adapt to changing weather conditions, has moderate soil requirements, and offers high green mass productivity. The goals of this study were to assess the possibility of using ash from Carpinus betulus aided by soil amendment with compost and HumiAgra in Zea mays cultivation and to determine the energy potential of maize. Wood ash had a relatively minimal effect on the combustion heat and calorific value of maize biomass. It increased the contents of C, H, S, N, O, and ash in the aerial parts of the maize. In addition, it positively affected the contents of organic carbon, total nitrogen, soil pH, sum of exchangeable base cations, total exchangeable capacity of soil, and degree of soil saturation with alkaline cations. In contrast, it strongly decreased the yield of maize, negatively affected the biochemical activity of the soil, and reduced the hydrolytic acidity of the soil. Soil amendment with compost and HumiAgra had positive effects on the heat of combustion; calorific value; the contents of C, H, S, N, O, and ash in the aerial parts of maize; and on the properties of the soil. In addition, they mitigated the adverse effects of wood ash on maize biomass and the enzymatic properties of the soil.
