“…Sideficient soils can be corrected by several sources that vary widely in total and plant-available silicon (Keeping 2017). Most research in Brazil tested calcium silicates and steel slag as Si fertilizers (Alvarez et al 2018;Camargo et al 2013;Deus and Büll 2013;Preston et al 2020). Such sources pose some drawbacks, such as low content of plant-available Si or high levels of heavy metals, requiring large amounts of fertilizer to reach the crop demand, or increase soil contamination risk.…”

Silicon (Si) fertilization can mitigate biotic and abiotic stresses and increase the yield of sugarcane. Considering the low availability of Si in tropical soils and the large amounts of fertilizer required by Si accumulating crops, concentrated sources of Si with good solubility may lead to more profitable fertilization management. In this context, we assessed the potential of an amorphous silica-based fertilizer (ASF) on increasing the soil availability and uptake of Si by sugarcane, the growth parameters, the stalk and sugar yields, and the damage caused by stalk borer (Diatraea saccharalis F.). Additionally, Si effects on the accumulation of nutrients by sugarcane were evaluated. The field trial was carried out in a randomized block design with four replications. The ASF was applied at five rates (0, 125, 250, 500, and 750 kg ha −1 ). The evaluation of the plants was performed 12 months after planting. Silicon available content in the soil layers assessed (0.0-0.2 m and 0.2-0.4 m) increased with Si fertilization. The Si concentrations in leaves and stalks were up to 5-and eightfold higher in ASF-amended plants than the control. The Si fertilization increased N, P, K, Ca, Fe, Mn, Cu, and Zn concentrations. Sugarcane growth parameters showed a positive relationship with Si in plants; the height and stalk diameter and the dry leaf biomass were 50, 58, and 71% higher in the 750 kg ha −1 ASF compared to the control, respectively. ASF also increased the contents of fiber, total sugar, and recoverable sugar. The accumulation of Si in the stalk reduced significantly the damage caused by the stalk borer. The ASF rates increased the yield of stalks, total and recoverable sugar, and the stalk borer's resistance, having great potential to boost sugarcane performance in Si-depleted soils in northeast Brazil.

This study explores whether Thermomagnesium (TM), a by-product of Ni ore mining, is an efficient fertilizer for maize. The effects of TM on soil pH, the supply of Si and Mg to the soil and plants, carbohydrate metabolism, grain filling, and yield were assessed in two simultaneous experiments performed in greenhouse conditions. Five TM doses were applied to two soil textures—clayey (0, 55, 273, 709, and 2018 mg kg−1) and sandy (0, 293, 410, 645, and 1260 mg kg−1). In general, the best results in soil and maize plants occurred at the highest TM dose for both soil textures (clayey 2018 mg kg−1 and sandy 1260 mg kg−1). The results demonstrated that in both soils, the concentrations of Mg and Si in the maize leaves increased with the dose of TM, similarly to that which occurred in the soil. Interestingly, in clayey soil, the soil pH increased linearly, whereas in sandy soil, the pH reached its maximum value between the two largest TM doses. The concentration of reducing sugars increased at the highest TM dose, whereas the concentrations of sucrose and starch decreased. The enhancement of carbohydrate partitioning led to higher maize growth, grain filling, and yield. Overall, the results clearly demonstrate that TM is a sustainable alternative fertilizer for maize and can be used for countless other crops and soil classifications, thus providing a suitable destination for this by-product of Ni ore mining.

Argon oxygen decarburization (AOD) slag is the by-product of the stainless steel refining process, which has caused considerable environmental stress. In this work, the utilization of AOD slag as mineral fertilizer for alfalfa (Medicago sativa L.) and perennial ryegrass (Lolium perenne L.) planting were investigated by pot experiments. The morpho-physiological parameters of biomass, plant height, root morphology and the biochemical parameters of malondialdehyde (MDA) content, superoxide dismutase (SOD) activity, catalase (CAT) activity, peroxidase (POD) activity, and chlorophyll were measured. The accumulation of chromium in plants was also determined for an environmental safety perspective. It was found that low rates (≤0.5 wt.% for alfalfa and ≤2 wt.% for perennial ryegrass) of AOD slag fertilization are beneficial to the growth of these two plants. However, the soil enrichment with higher AOD slag amounts resulted in the reduction of biomass, plant height, and root growth. Compared with the alfalfa, the perennial ryegrass showed higher tolerance for AOD slag fertilization. The toxicity of the utilization of AOD slag as mineral fertilizer for perennial ryegrass planting is slight. Health risks induced by the consumption of the alfalfa grown on the soil with high AOD slag rates (≥8 wt.%) were detected.
