Want better yields and the same or more profit?
Stop buying pesticides, rotate more crops over longer periods,
and mix in animals.
Yet another study confirms this.
Oh, and a hundred times less
in streams, and presumably also less pesticides in the food going to market.
The study was done on land owned by Iowa State University called the
Marsden Farm. On 22 acres of it, beginning in 2003, researchers set
up three plots: one replicated the typical Midwestern cycle of
planting corn one year and then soybeans the next, along with its
routine mix of chemicals. On another, they planted a three-year
cycle that included oats; the third plot added a four-year cycle and
alfalfa. The longer rotations also integrated the raising of
livestock, whose manure was used as fertilizer.
The paper's Figure 3 (above)
illustrates that labor increased with crop rotation length,
but so did yield, and profit remained the same or better.
How can this be?
CRITICISM: GM has been in the food chain for years in the US. Why
isn't there evidence of people and animals suffering more tumours or
dying earlier? Why aren't Americans "dropping like flies?"
RESPONSE: Most GM crops are fed to farm animals, which have
relatively short lives either for meat or dairy production and so
there is probably not enough time for tumours to develop.
Americans have been eating GM food (soya, maize) for only a
relatively short time in significant quantities in processed foods.
So it may be too short a period for long-term effects such as tumour
formation to be noticeable. However, we should also note that there
is no labelling of GM foods in the USA and no monitoring of the
population for ill-effects, so if GM food were causing ill health
this would be going undetected.
Ill effects of Roundup went mostly unstudied until scientists
in places like Austria (the first study above) and France (the second study)
Roundup (you know, the stuff that's sprayed on cotton, soybeans,
peanuts, and corn and drifts across the road) causes DNA damage
even when diluted down to 450 times less than what's used in agriculture,
according to a scientific study from February 2012.
Glyphosate (G) is the largest selling herbicide worldwide; the most
common formulations (Roundup, R) contain polyoxyethyleneamine as
main surfactant. Recent findings indicate that G exposure may cause
DNA damage and cancer in humans....
Since we found genotoxic effects after short exposure to
concentrations that correspond to a 450-fold dilution of spraying
used in agriculture, our findings indicate that inhalation may cause
DNA damage in exposed individuals.
It's probably not even the "active" ingredient, glyphosate,
that's causing this DNA damage,
more likely one of its "inert" ingredients.
