“…Among the positive aspects of the WBA application to the soil, an increase in the content of TC is noted in the literature [21,22]. The research conducted by Symanowicz et al [14] indicated that the use of 1 Mg WBA ha −1 may result in an increase in soil fertility by about 160 kg of TC.…”

“…Apart from excessive alkalization of soils under the influence of WBA applications, some researchers have indicated a possible adverse impact of WBA on soil EC [13,22]. This problem is very important, because excessive soil salinity may deteriorate the conditions for the plant growth and plant root development.…”

“…According to the literature, the application of WBA to soil enhances the soil's physical properties [17] by improving its texture, reducing density, optimizing the pH value [13,14,[17][18][19][20][21], and increasing the buffer capacity of the soil [13,18]. In addition, WBAs promote soil aeration [13,18], improve permeation, water retention [13,18,22], and porosity [22], and reduce soil crusting [13]. The addition of WBA to soil increases the content of organic carbon and essential nutrients for plants [22], including Mg [19,21,23], K, P, Ca [18,21,23], Na, and S [19] and micronutrients Zn [18,19], Fe, Cu, Mn [18], and B [18,23].…”

The use of WBA, by changing the sorption properties [24] and alkalization of soils, can reduce their content of exchangeable aluminum [10] and additionally reduce the mobility of heavy metals [13,18].…”

This research concerned the possibilities of the natural management of ash, which is a waste product obtained in the process of burning wood chips in a bio-heating plant. The basis of the research was a pot experiment, which was carried out in a greenhouse of the University of Warmia and Mazury in Olsztyn, Poland. This experiment dealt with the influence of increasing doses of wood biomass ash added to soil on selected soil properties. The soil used for the pot experiment was taken from the arable layer (0–25 cm) of the soil. It was characterized by acidic reaction, low salinity, and an average content of total carbon (TC). The test plant was corn. Soil analysis after plant harvest showed an increase in pH and a significant improvement of soil sorption properties, without causing an excessive increase in soil salinity. In addition, a significant increase in the content of available K, P, and Mg was observed, which at the highest dose of WBA reached: 121.9; 109.3, and 41.33 mg kg−1 of soil, respectively. The content of trace metals: iron (Fe), manganese (Mn), zinc (Zn), copper (Cu), cadmium (Cd), lead (Pb), cobalt (Co), chrome (Cr), and nickel (Ni) in the soil was quite varied but did not exceed the permissible values for agricultural soils. The content of available forms of these trace metals at the highest dose of WBA was, respectively, 1004, 129.9, 8.70, 2.08, 5.54, 0.195, 1.47, 0.97, and 1.92 kg−1 of soil. The results confirmed the significant fertilizing potential of wood biomass ash.

“…In agriculture, fly ash is mainly used as a soil amendment to improve physical properties (Islam and Islam, 2022). As an amendment, it can increase crop yield (Varshney et al, 2022), while as a fertilizer, it can help leguminous species to fix atmospheric nitrogen (Kumar and Kumar, 2022). A comparative field experiment on sunflower planting with fly ash, SAP, and PAM as modifiers showed that they effectively improved the net photosynthetic rate, stomatal conductance, intercellular CO 2 mole fraction, and the transpiration rate of plants (Xu et al, 2017).…”

Effects of different factors on fly ash-based functional soil and its oat grass cultivation

et al. 2022

Using fly ash as the main matrix for plant ecological restoration is effective for constructing a sustainable and ecological environment. The relevant properties of functional soil change due to different factors. Based on the orthogonal experiment of functional soil and the pot experiment of oat grass, fly ash was used as the matrix material for functional soil. Afterward, MX (large granules dispensing certain nutrients), SJJXWS (a water-retaining agent), and AF (a nutrient conditioner) additives were added to study the physical, chemical, and agronomic properties of functional soil, such as the emergence rate and weight of plants. The results showed the high pH and conductivity of functional soil, implying alkaline soils with high salinity. The contents of organic matter and available phosphorus and potassium were relatively high, indicating its high nutrient content. Further analysis revealed that the MX was the key factor affecting functional soil’s electrical conductivity and evaporation, and thus, the corresponding plant emergence rate, plant weight, and other related indicators. The influence of each factor on the corresponding plant emergence rate, plant weight, and other indicators of functional soil was arranged in the order of MX (large granules dispensing certain nutrients), SJJXWS (a water-retaining agent), and AF (a nutrient conditioner). The optimum additive ratio in functional soil was 0.45 t·hm-2 of MX, 0.12 t·hm-2 of SJJXWS, and 1.65 t·hm-2 of AF. The results of this study provide a theoretical basis for further development of functional soil for ecological cycle restoration purposes.
