Organic (Natural) versus Chemical (Inorganic)
argument continues. The organic proponents say only organic should
be used. The chemical proponents have their argument of high analysis
and quicker availability.
don't we consult Nature and see how she has been feeding plants life
since the very beginning?
of the fertilizers called "chemical" occur naturally in
Nature. In fact, that is where man discovered them. Ammonia, ammonium,
ammonium sulphate, nitrites, nitrates, potassium sulphate, calcium
phosphate, urea are some of them. But seldom are these chemicals found
in the pure state. In Nature, they are almost always bound up in rock
or in an organic form with other elements. Or they may be found in
a state of transition.
chemical fertilizers always have a high total NPK, from 20 to 60 percent
or more. The total NPK for organic fertilizer blends will always be
low. Fourteen percent is about as high as it gets.
balance of the ingredients in the chemical fertilizer bag, aside from
the NPK, is usually made up of inert filler or possibly a chemical
that isn't needed. The balance of the ingredients in the organic fertilizer
bag beyond the NPK are all necessary soil nutrients. The fact that
the material is organic means it came from a once-living entity-plant,
animal or a blend of both-which tells us that every ingredient
there is important to life. In the best organic fertilizers, everything
in the bag is needed and is in correct proportions to feed and sustain
the next generation of life.
chemical fertilizer formulas that contain major, minor and trace elements
are labeled "Complete." That is really a false statement.
It takes much more than a few chemicals to maintain the healthy soil
and grow healthy plants. For example, there is very little, if any,
carbon in a bag of chemical fertilizer. When a plant or animal body
is analyzed, one of the most abundant elements in it is carbon, in
the form of energy, mainly carbohydrates.
order for a plant to be properly fed, whether with chemical or natural
fertilizer, the microbial life in the soil must first process the
fertilizer into a substance and release it in the correct amounts
that are perfect for a plant to absorb. In order for the microbes
to perform this service, they must have energy. They are not in the
presence of sunlight, nor do they have chlorophyll like higher plants,
so the microbes must get their energy from decaying plant or animal
matter in the soil.
bag of organic fertilizer has all the carbon/energy to meet the needs
of the soil microbes. A bag of chemical fertilizer has no energy.
If organic matter is not already present in the soil, the chemicals
can quickly become stressful, even toxic, to the plants. This causes
plants to be susceptible to disease and insect problems.
fertilizers are believed to be slower acting than the chemical fertilizers.
This is true to a degree. Being a lower NPK analysis and slower acting,
organic fertilizers can be used in higher volume around plants without
danger of burning. However, there are some organic fertilizers that
are fast acting, such as bat guano or fish meal, that can show results
as quickly as the chemical fertilizers do. They are still slower to
burn the plants than the chemicals and last much longer in the soil.
chemical fertilizers are impregnated or coated with a microbe inhibitor
and some substance to keep them from quickly dissolving, they must
be used very cautiously. Especially in sandy soils, they can burn
the roots of the plants and quickly leach beyond the reach of the
roots. They generally end up polluting a water supply because they
are too quickly dissolved and moved out of the soil. In heavy clay
soils or any soil with a high organic and humus content, this is less
of a problem.
fertilizers that are blended to perfectly fit a given soil and then
used in the correct season and correct amounts can do nothing more
than grow a plant. They do not build or sustain a healthy soil. Organic
fertilizers contain the energy and the many other things that continually
build soil fertility, crumb structure, increased water holding capacity,
food for all the beneficial soil life, condition the soil and contribute
to the hundreds of other yet-unknown things that cause a plant to
grow healthy and perfect.
healthy and perfectly grown plants can feed and support healthy and
perfect animal and human life.
dig root crops such as sweet potatoes when the soil is too moist.
If dug when the soil is on the dry side, the root crops store much
better and longer.
