KICKER: NO GARDEN-VARIETY MESSAGES IN TOMATOES' TRANSMISSIONS
PAUL/ANCHOR: For our final story, we ask the question: have your tomato
plants been calling QRZ? Then, this is obviously no garden-variety
special event. Mike Askins, KE5CXP, explains.
MIKE: Those of us who think about, talk about, dream about, antenna
farms, may need to look no further than a tiny packet of seeds. No,
we're not suggesting you plow your soil to let little yagis and
hexbeams and delta loops burst and flower across acres of sun-drenched
furrows.
We're talking tomatoes. Yes, tomatoes. Researchers in Huntsville,
Alabama, have just published a paper, studying the transmission of
electrical signals through the soil by, of all things, tomato plants.
The work was reported on the website PHYS.ORG, and cites the efforts
of a scientist associated with the University of Alabama, and a
biochemistry professor at nearby Oakwood University. The observations
by the pair, date back work they began in 2017. It's all about
propagation - in this case, electrical signal propagation within,
and between plants. Researchers Yuri Shtessel of Huntsville, and
Alexander Volkov of Oakwood, used mathematical modeling, to plot the
electrical patterns. According to the article, plants' electrical
signals can propagate, for instance through the roots, and into the
soil to another species, such as a nearby tree, by making use of fungi
in the soil. The soil is seen as a conductor of electricity, and the
signal is received -- but there is no guarantee of good copy, or even
being understood.
As Yuri Schtessel writes: [QUOTE] "No study of the cognitive processing
of the electric signals passed, and received by the plants was
accomplished." [ENDQUOTE]
It seems that we hams aren't the only ones who suffer when our signals
end up down in the mud.
For Amateur Radio Newsline, I'm Mike Askins, KE5CXP.
