Il est surprenant d'apprendre que les engrais peuvent
causer plus de dommage que les pesticides. Pourtant, c'est un fait.
Certains engrais contiennent des composés nocifs soit qui polluent tout
court ou qui endommage le sol.
Il y a moyen de faire
pousser des légumes sans avoir recours
aux engrais synthétiques. La réponse est simple :
"le compost". Par ailleurs, plus
les engrais chimiques sont employés,
plus le sol en

êtres humains et les drogues.

ertilizer is easy to buy, easy to use, and conveniently bagged, ready to go! It
can be picked up at the supermarket, home centre, or even the drug store! But these
synthetic chemical fertilizers, are causing great harm to the environment. In fact, more
than half of the fertilizer used on lawns and gardens each year is washed away and wasted!
These water soluble fertilizers usually contain products like ammonium nitrate or
synthetic urea, by-products of the oil and gas industry. They are highly soluble, can burn
plants and urea; if mixed with formaldehyde, is a suspected carcinogen. Furthermore, they
can kill soil bacteria, one of the keys to a healthy garden.
Should gardeners be as concerned about fertilizer use as about pesticide
use? Absolutely! The damage from synthetic chemical fertilizer use is probably more far
reaching than that of pesticide use simply because more fertilizer is used. Also, soil
micro-organisms are not encouraged which, in turn, can alter the way soil holds water and
nutrients, which can eventually cause the soil structure to collapse. Lawns and gardens
all over the world are "chemically dependent"; like human drug users. The more
landscapes and gardens are managed, the more the treadmill of chemical application is
increased. Eliot Roberts, director of the Lawn Institute, a U.S. based seed association,
states, "The more chemicals you use, the more you disturb the natural biological
processes that convert organic matter into nutrients to keep the lawn going." But
there are safe alternatives to synthetic fertilizers that are not limited to the barnyard
Nitrogen (N), phosphorus (P) and potassium (K) are the three major nutrients in a bag
of fertilizer. The number ratings such as 6-8-6 or 20-20-20, indicate the percentage of
nitrogen, phosphorus and potassium in that particular bag. Industry markets chemical
fertilizers as "organic based" or states claims of unimaginable results; so
buyer beware and do not forget the old adage, "you get what you pay for."
Is compost enough to fertilize plants? Yes was the assumed answer until studies were
done that discovered how much was being demanded of the soil.
While compost is the ultimate in soil amendments and a humus builder that enables soil
microorganisms to flourish and give soil nutrients a stable home to live in, it does not
contain enough available nutrients for most plants to thrive in. What plants really want
is the right combination of compost and non-synthetic fertilizer. Compost spread at the
rate of 9 cubic yards per 100 square feet yields the correct amount, a 1 inch layer.
As well, soil micro- organisms benefit the most if the compost is left on top of
the soil as opposed to digging it in. By not digging in compost, you help maintain humus
levels in soil and in turn control over activity of soil bacteria which consume too much
nutrients in soil. Chemical fertilizers, because of their highly soluble nature, will
deplete natural humus levels at a rapid rate.
Buying a bag of synthetic 6-8-6 fertilizer from the grocery store or lumber yard does
nothing to ensure that gardens are being fed in a sustainable way. It is known that one
cannot live on potato chips; even though they taste great and "fill a hole",
they dont give the body good nutrimental value. Think of fertilizers derived from
mineral, plant and animal sources as the "meat and potatoes" of the garden,
providing valuable nutrition to the garden which in turn gives back healthy and nutritious
plants to eat. Feeding the soil feeds your plants.
The Canadian EarthCare Society (EarthCare), is concerned about the continued use of
unsustainable agricultural products including synthetic chemical fertilizers and
pesticides and is pleased to be able to provide garden fertilizers that dont
contaminate groundwater or destroy valuable soil micro-organisms.
In association with Gaia Green Products Ltd. of Grand Forks, B.C., EarthCare is now
able to offer dozens of products that originate as minerals, plants or animals. These
non-synthetic fertilizers include glacial rock dust, bone meal and alfalfa meal along with
blended formulations. All are a non-synthetic source of food for plants and can be used in
certified organic agricultural practices. Properly used, these fertilizers will feed
plants and still remain safe for ground and stream water courses. EarthCare is a
non-profit environmental organization that has been based in Kelowna for nearly 15
years. Profit from fertilizer sales will help to support the organizations mandate
to protect the environment.
