Scientists have discovered a connection between birdsong and plant growth. Within the same ecosystem, there is an interaction between fauna and flora, with birdsong acting as “acoustic fertilizer,” according to Ernst Zürcher, a forest engineer.
Fruit growers had already experimented with this phenomenon by playing birdsongs through speakers on their farms.
A researcher at the University of San Diego has highlighted the effect of acoustic vibrations on plant growth, particularly on the opening of plant stomata, which are respiratory openings. These stomata open more readily when they hear music or birdsong.
Concurrently, tests have shown that fertilizer applied to a plant with open stomata has a more significant effect. This makes it possible to propose a combination of frequencies and fertilizers that are beneficial for a given crop.
