Medical marijuana growers swear by it: that music from different styles enhances the growth of their plants. This is the reason why parents in the 80s played Mozart to their embryos.
There may be something to it:
Soil microbes enjoy bouts of white noise finds scientists in a new research project. Fungal soil microbes that promote plant growth seem to get a boost from white noise. Researchers say it’s like hosting an underground rave.
When scientists periodically played a noise similar to radio static to Trichoderma harzianum, the fungi grew bigger and produced more spores than other samples grown in a soundproof booth. The vibrations might stimulate mechanoreceptors in Trichoderma’s cell walls, which alters the expression of genes involved in growth, suggest researchers.
Barely audible to human ears, healthy soils produce a cacophony of sounds in many forms – a bit like an underground rave concert of bubbles and clicks.
Special recordings made by Flinders University ecologists in Australia show this chaotic mixture of soundscapes can be a measure of the diversity of tiny living animals in the soil, which create sounds as they move and interact with their environment.
With 75% of the world’s soils degraded, the future of the teeming community of living species that live underground face a dire future without restoration, says microbial ecologist Dr Jake Robinson, from the Frontiers of Restoration Ecology Lab in the College of Science and Engineering at Flinders University.
This new field of research aims to investigate the vast, teeming hidden ecosystems where almost 60% of the Earth’s species live, he says.
“Restoring and monitoring soil biodiversity has never been more important.
“Although still in its early stages, ‘eco-acoustics’ is emerging as a promising tool to detect and monitor soil biodiversity and has now been used in Australian bushland and other ecosystems in the UK.
“The acoustic complexity and diversity are significantly higher in revegetated and remnant plots than in cleared plots, both in-situ and in sound attenuation chambers.
“The acoustic complexity and diversity are also significantly associated with soil invertebrate abundance and richness.”
Over in Israel this team was the first to show that plants can speak.
