Thermomagnesium: A By-Product of Ni Ore Mining as a Clean Fertilizer Source for Maize

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