The Effectiveness of Electric and Magnetic Fields on Plant Growth

Overview

To meet the world’s growing demands for food, the agricultural industry is constantly striving to find ways of efficiently improving food production. Electroculture is a movement that claims that electric currents and magnetic fields can enhance plant growth. The efficacy of its methods has been reported but hardly studied scientifically. This project hypothesizes that if plants are cultivated under the influence of electric currents or magnetic fields, then their growth can be stimulated due to an enhancement in nutrient uptake. The experiment was split into a macroscopic and microscopic component to test if the effect of magnetism occurred on a cellular level. Pea and cucumber seeds were exposed to a large magnet, small magnets, 1.5V current, copper and steel rod, and copper and steel Fibonacci coil and grown for 22 days. Plant masses, root lengths, leaf counts, and stem lengths were then measured. Visually, the plants grown in the magnet, current, and coiled rod groups appeared much more robust than those in the control group. The 1.5V current had the greatest statistically significant impact on plant growth, followed by the Fibonacci copper coil. The small and large magnets also had a tangible benefit on plant growth. The two copper apparatuses yielded greater growth than the control and their steel counterparts. This implies a possibility that the copper conducted atmospheric energy better, or that it might have leached into the soil and acted as a micronutrient to the plants. For the microscopic component, Chlamydomonas reinhardtii (algae) were cultivated under different levels of magnetism, documenting the cell counts, cilia lengths, and swimming speeds. Magnetic field did not seem to benefit the algae. Ultimately, the hypothesis that electric current and magnetic fields benefit plant growth was supported. Instead of impacting the plants on a cellular level, magnetism likely affects the soil and physical uptake of nutrients. The conclusions from this experiment show that the use of electric currents, magnetic fields, and copper rods holds promise for enhancing plant cultivation, which could have a profound impact on the agricultural industry.
