The world's largest experiment on the effect of electric techniques for plant growth, conducted by the Chinese government, has produced findings that could have a profound impact on the future of farming. The study, carried out over 2018, found that growing vegetables in greenhouses under high-frequency bare copper wires placed three metres overhead increased growth output by between 20% and 30%, while reducing the use of fertilisers by a similar amount and almost eliminating the use of pesticides. The electricity was found to kill bacteria and diseases in the air while doing no harm to the plants.
