PLANT & SOIL HEALTH
the exposure of an organism to low doses of stress,
he said.
Dragan Macura, founder of organic fertilizer
manufacturer AgroThrive, which uses fish inedibles,
cited studies showing how organic fertilizers
better protect and interact with plants than
conventional products.
Blending organic fertilizers with conventional
fertilizers improves plant/microbe interaction in the
rhizosphere, the area of soil surrounding plant roots,
he said. In grapes, the blending can improve yields,
lower heavy metals in the soil and leaves, and improve
the quality of grape
must (the first step in
winemaking), leading
to better wine quality,
Macura said.
Issac Carlson, a
Pasco area wheat
grower who diversified
into winegrapes,
discussed how he
transitioned to farming
regeneratively. One
step is using a fishbased
fertilizer.
" I was always told
by people that yes,
you may be able
to go organic, but,
eventually, the weeds
will get you, " he said.
Regenerative agriculture
focuses on soil health to
reduce weed and pest
pressures, and using organic
herbicides and pesticides.
" You will have to go back to conventional to control
the weeds. "
Carlson added various regenerative components to
his conventional spray program, saw how it worked
and added more to reduce toxic material use.
" I was told by other grape farmers that if you have
bindweed, a tough one, it's like a death sentence in
that you can't ever get out of it, it goes up the canopy
and engulfs the grapes, " Carlson said. " But what
I've learned in seven years, instead of what I was
told, that weeds will kill you and you will have to go
back to conventional, the weeds are actually getting
less. They're still there, but are not increasing. The
pressure is decreasing. It's very manageable now. "
Gordon said Carlson's experience in reducing levels
of fertilizers and pesticides makes his plants better.
" When you begin to replace and eliminate all toxic
materials that have secondary and negative side
effects, then you become regenerative organic, "
Gordon said. " I don't care if you're certified or not. I
am talking about growing things in a non-toxic manner
that you can eat or get anything on you or lick it, that
you're applying to your crops. This can be done at
once, but most of the time it's a transition process. "
