“…Crushed basalt provided the only supplemental source of Si, Ca, K and Sr, and uptake and accumulation of these elements in Sorghum shoots, allied to increases in soil pH (see below), indicates mass transfer from the source rock on the timescale of the experiment. Increased shoot Si can enhance the resilience of plants to abiotic stresses, including drought, salinity, heat (Burghelea et al, 2015; Korchagin, Caner, & Bortoluzzi, 2019) and resistance to lodging due to wind or rain (Artyszak, 2018) as well as to biotic attack (Meharg & Meharg, 2015; Van Bockhaven, De Vleesschauwer, & Höfte, 2012). Shoot Si increases following soil silicate treatments, for example, provided direct protection from pests and diseases for major C 3 (soybean, wheat and rice) and C 4 crops (sugarcane and maize) and indirect protection via changes in the release of herbivore‐induced plant volatiles enhancing parasitoid attraction (Liu et al, 2017).…”

Land-based enhanced rock weathering (ERW) is a biogeochemical carbon dioxide removal (CDR) strategy aiming to accelerate natural geological processes of carbon sequestration through application of crushed silicate rocks, such as basalt, to croplands and forested landscapes. However, the efficacy of the approach when undertaken with basalt, and its potential co-benefits for agriculture, require experimental and field evaluation. Here we report that amending a UK clay-loam agricultural soil with a high loading (10 kg/m 2 ) of relatively coarse-grained crushed basalt significantly increased the yield (21 ± 9.4%, SE) of the important C 4 cereal Sorghum bicolor under controlled environmental conditions, without accumulation of potentially toxic trace elements in the seeds. Yield increases resulted from the basalt treatment after 120 days without P-and K-fertilizer addition. Shoot silicon concentrations also increased significantly (26 ± 5.4%, SE), with potential benefits for crop resistance to biotic and abiotic stress.Elemental budgets indicate substantial release of base cations important for inorganic carbon removal and their accumulation mainly in the soil exchangeable pools.Geochemical reactive transport modelling, constrained by elemental budgets, indicated CO 2 sequestration rates of 2-4 t CO 2 /ha, 1-5 years after a single application of basaltic rock dust, including via newly formed soil carbonate minerals whose longterm fate requires assessment through field trials. This represents an approximately fourfold increase in carbon capture compared to control plant-soil systems without basalt. Our results build support for ERW deployment as a CDR technique compatible with spreading basalt powder on acidic loamy soils common across millions of hectares of western European and North American agriculture.

“…However, Brazil imports approximately 81% of its fertilizer [9,10]. A potential alternative source of nutrients is mining by-products [11,12], which would reduce the environmental problem of rock mining while providing a cleaner, domestic option for soil fertilization [13]. The use of by-products as a fertilizer in agriculture is an effective means of improving soil quality, increasing crop yields, and mitigating environmental impacts, while generating a new source of revenue [14].…”

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.

“…The use of rockfall is a viable and sustainable alternative (ALMEIDA JÚNIOR et al, 2020). As conventional agriculture is characterized by the large-scale use of chemical fertilizers and biocides to provide good conditions for the development of cultivated plants (KORCHAGIN et al, 2019), the possibility of reducing the use of these inputs is one of the main factors that justifies the application of rock powder as a soil remineralizer (RAMOS et al, 2015). The use of rock powders in soil fertilization was initially proposed by Hensel (1894), highlighting the benefits of using ground rocks in agriculture, known as stone flour or soil remineralizers (LOPES et al, 2014).…”

Although different studies have shown beneficial effects of using rock powder on plants, no research has been done to determine the influence of adding this input to the strawberry growing substrate (Fragaria X ananassa Duch.). Thus, we investigated whether proportions of rock powder added to the cultivation substrate interfere in the agronomic performance of strawberry. The treatments tested were five proportions of rock powder (0%, 15%, 30%, 45% and 60% of the volume of the container). The experiment was designed in randomized blocks, with four replications. The supply of fertigation was reduced by half in order to verify whether the rock powder would be able to supply part of the nutrient demand required by the strawberry. The determination coefficient obtained was 0.83, indicating that the total production of fruits (TP) was explained in 83% by the proportions of rock powder added. We also observed that TP decreased linearly with the increase in the proportion of rock powder added to the cultivation substrate. TP was also negatively associated with the increase in the density of the culture media. In conclusion, increasing amounts of rock powder added to the cultivation substrate create a denser environment, not providing the necessary quantities for the development of the strawberry and this reduces its productive potential.
