Organic or Chemical Growing
Science has brought us wonderful benefits in our daily
life and produced a revolution in farming and food production.
Weak, malnourished crops were decimated by pests and
diseases until science discovered fertilisers, herbicides
and pesticides. NPK balanced fertilisers cured the deficiencies
producing healthy strong plants, herbicides destroyed
weeds competing for resources and pesticides destroyed
the pests. The soil was just a medium to hold the nutrients
and support the plants.
Well, that was the theory..
The results could be somewhat different. Overdoses
in nitrogen fertiliser resulted in run off to watercourses
and massive problems in the rivers. Deficiencies developed
in the plants due to lack of micro-nutrients, the ‘vitamins’ of
the plant world. Pesticides killed friend as well as
foe – eventually resulting in more fast breeding
foes and problems as they infiltrated the food chain.
Nowadays we can be more sophisticated. We realise
that we are part of an eco-system and alterations to
that eco-system can have unexpected consequences. The
soil is a complex system of itself and natural methods
nurture nature rather than attempting to replace it
with a simplistic control.
Working with nature
The organic approach of working with nature means
you have a massive army of helpers on your side. Bacteria
in the soil converting chemicals to useful forms for
your plants, earthworms breaking soil and aerating it,
predators eating your pests.
Safety
This most compelling reason I have for organic gardening
is safety. Now before some massive chemical company
sues me for suggesting their products are not safe,
let me explain my reasoning. Before a product is released
to the market it is tested and a ‘safe level’ is
determined. So we know mice or rats can eat X mg of
a product without harm – BUT – what if the
plant we eat has X mg of product A and Y mg of product
B?
There is no way that all the pesticides can be tested
in combination, if any maths expert would like to send
me a proof of this, I would appreciate it, and so we
can not be sure of safety. Neither can we test the effect
of eating these combination chemical cocktails over
many years. Why take the risk?
How Organic?
Being ‘organic’ is not, in my opinion,
an either or choice. I avoid the use of artificial fertilisers
but do use fish, blood and bone. I do not use any pesticides,
but will use herbicides in exceptional circumstances
such as my Marestail problem. There I use Amicide whose
effects are fairly clear-cut and documented.
The worst problem is…. The Slug. These little
creatures can happily destroy a row of seedlings in
a night. Luckily there are now ‘organic’ slug
pellets as well as other organic solutions. Expensive
but much safer than conventional solutions.
