“…This process improves the solubility of SiO 2 in a colloidal form, as confirmed by an analysis using an inductively coupled plasma-optical emission spectrometer (DV3300, Perkin Elmer, USA). The resulting material was ground to 20-50 µm according to Jung et al (2014) and Yoon et al (2016). The chemical composition of PRC consisted of SiO 2 (31.1%), Na 2 O (25.6%), Al 2 O 3 (19.0%), Fe 2 O 3 (7.47%), K 2 O (1.30%), CaO (0.95%), TiO 2 (0.94%), MgO (0.73%), and other materials (13.91%).…”

“…The agricultural field has reported red clay availability (Kim et al, 2014); however, the prominent components that constitute red clay are insoluble and exhibit limited absorption in soil and plants, even when used as a powder (Seo et al, 2014a). Fortunately, processed red clay (PRC; Patent #0886082, Republic of Korea) is designed to remove impurities and enhance mineral bioavailability and to improve soil fertility and microbial activity (Jung et al, 2014;Yoon et al, 2016). Biofertilization utilizes plant and animal wastes to enrich soil with organic matter and nutrients, employing microorganisms to metabolize these by-products for enhanced absorption by plant roots (Montesdeoca-Flores et al, 2024).…”

Global agricultural practices emphasize the demand for environmentally friendly and sustainable production strategies. Therefore, this study investigated the impact of processed red clay (PRC), an eco-friendly material derived from red clay, and a microbial fertilizer containing Lactobacillus fermentum (MFcL) on tomato growth, fruit quality levels, and soil properties. Tomatoes were transplanted and cultivated in open-field experiments. PRC, MFcL, and PRC+MFcL treatments were applied at 500 mL•plant -1 four times at seven-day intervals. The chlorophyll content of tomato leaves decreased over time, with MFcL significantly affecting the chlorophyll content and photosynthetic quantum yield (F v /F m ). Significant differences in certain fruit growth traits, including the fruit width, weight, and fruit shape index, were observed among the treatments. Significant variations (p < 0.05) in the total yield and fruit cracking percentage were also found between the non-fertilizer (NF) and PRC treatments. The application of PRC significantly reduced the fruit cracking percentage and enhanced the crude protein and fat content of the fruits compared to the NF treatment. In addition, MFcL significantly increased the soil-available phosphorus content and decreased pH levels, and PRC+MFcL promoted rhizobacterial growth, showcasing the potential of these biofertilizer treatments. The combined treatment of PRC and MFcL proved effective for growing tomatoes in open-field conditions. Further research should explore various PRC and microorganism combinations to gain a comprehensive understanding and to assess the potential of their rational application to crops.

“…Hence, more improvement is necessary to make it practical. Yoon et al [10] reported economical synthesis of complex silicon fertilizers using loess with loess processed materials (LPM). LPM was produced by adding 30% NaOH at 12008C for 1 h. Treatment with a 200-fold diluted LPM solution resulted in increases of 7.8 and 8.3% in the weight and quantity of tomatoes, respectively, and 31.7% in the quantity of cucumbers.…”

Recycling of iron ore tailings (IOT) which are by‐products of iron ore processing has attracted attention but there have been few studies on their use as fertilizers. In this study, slow‐release silicon fertilizers are prepared from iron tailings by solid‐phase sintering and characterized by X‐ray diffraction (XRD) and scanning electron microscopy (SEM). The solubility results acquired from the optimal sample (Si‐IOT) indicate that the available SiO2 is 20.77% and that of available K2O is 18.43% in 0.50 mol L−1 HCl. For 10 g of Si‐IOT in 200 mL of distilled water at 25°C, the cumulative release of K2O is 4.32% in the first day and 19.4% in 28 days and that of SiO2 is 2.12% in the first day and 16.30% in 28 days. The performance satisfies the Chinese national standard for slow‐release fertilizers and Chinese agricultural standard for silicon fertilizers. The results obtained from Si‐IOT pertaining to release of heavy metals indicate that heavy metals will not affect the quality of the crops and pakchoi growth is improved. Hence, they are potential raw materials for slow‐release silicon fertilizers. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1011–1019, 2018

To comprehensively reuse the leaching residue obtained from lead-zinc tailings, an active silicon adsorbent (ASA) was prepared from leaching residue and studied as an adsorbent for copper(II), lead(II), zinc(II), and cadmium(II) in this paper. The ASA was prepared by roasting the leaching residue with either a NaCO/residue ratio of 0.6:1 at 700 °C for 1 h or a CaCO/residue ratio of 0.8:1 at 800 °C for 1 h. Under these conditions, the available SiO content of the ASA was more than 20%. The adsorption behaviors of the metal ions onto the ASA were investigated and the Langmuir, Freundlich, and Dubinin-Radushkevich isotherm models were used to analyze the adsorption isotherm. The result showed that the maximum adsorption capacities of copper(II), lead(II), cadmium(II), and zinc(II) calculated by the Langmuir model were 3.40, 2.83, 0.66, and 0.62 mmol g, respectively. The FT-IR spectra of the ASA and the mean free adsorption energies indicated that ion exchange was the mechanism of copper(II), lead(II), and cadmium(II) adsorption and that chemical reaction was the mechanism of zinc(II) adsorption. These results provide a method for reusing the leaching residue obtained from lead-zinc tailings and show that the ASA is an effective adsorbent for heavy metal pollution remediation.
