Magnetic Field Applications in Plant Growth
Summary
Plants are sensitive to magnetic fields beyond the geomagnetic baseline. Recent work reveals that controlled application of static, pulsed and extremely low-frequency fields can enhance seed germination, seedling vigour, root architecture and photosynthetic capacity. Applications range from pre-sowing treatments of seeds to irrigation water magnetisation. Experimental evidence indicates that magnetopriming not only accelerates imbibition and early establishment but also modulates antioxidant systems, stress resilience and nutrient uptake. At the cellular level, altered ion fluxes, enzyme activities and gene expression drive improved water and solute transport, while enhanced chlorophyll and carotenoid content under magnetic treatment yields higher quantum efficiency of photosystem II. These effects have been reported across major crops including maize, soybean, lettuce and sunflower, with benefits in saline or heavy-metal-contaminated soils. The field-scale potential includes yield increases, reduced agrochemical inputs and mitigation of abiotic stress, underscoring the global significance of magnetic field applications in sustainable agriculture.
