Interactions of magnesium with other nutrients in horticultural cropping systems.
| Nutrient | Type of interaction | Effects on crops | Strategies to address nutrient imbalances | References |
|---|---|---|---|---|
| Calcium | Antagonistic | Lower magnesium intake | Adjust calcium-magnesium ratio | (Tang and Luan, 2017) |
| Phosphorus | Positive/Competitive | Lower availability of magnesium | Optimisation of phosphorus application rates | (Marschner, 2011) |
| Potassium | Synergistic | Improved magnesium absorption | Maintain balanced K to Mg2+ ratio | (Xie et al., 2021) |
| Nitrogen | Interaction/Competition | Altered magnesium distribution | Adjust nitrogen-magnesium ratio | (Fageria and Oliveira, 2014; Peng et al., 2020; Potarzycki et al., 2022) |
| Zinc | Interaction/Competition | Impaired magnesium absorption | Optimise the zinc output quantities | (Sadeghi et al., 2021) |
| Iron | Interaction/Competition | Lower magnesium intake | Optimise the application of iron | (Sadeghi et al., 2021) |
