a few words about chemical fertilizers...
Fertilization with high concentrations
of Nitrogen, Potassium, and/or Phosphorus (N-P-K such as 15-15-15
or 20-20-20), stimulates rapid initial plant uptake of trace minerals
(also known as trace elements) without providing for their replacement.
It is common knowledge that excessive nitrogen reduces the valuable
calcium available to the plant. Calcium is a "cation",
together with Magnesium, Potassium, and Sodium. A reduction in the
available Calcium, always leads to an imbalance in the "cation
exchange". If cations are out of balance, anions will also
not work properly, nor will several important trace elements.
The question now is no longer whether to re-mineralize,
but where to get the best universal rock dust.
Excessive Nitrogen use is also leading
to a "tightening" of vast amounts of soil on agricultural
land. Additionally, a mostly unknown fact is that the carrier
materials for chemical fertilizers can be sewage sludge,
and sludge represents about 80% of the weight of that fertilizer.
This type of granulated fertilizer is commonly used for lawns
Liquid fertilizer, which is widely
used in commercial agriculture, is causing the leaching of a large
amount of N-P-K into the ground. This is one of the most
serious environmental problems we have today. The government
will soon require water run-off impact permits if this problem isn't
dealt with by industry and consumers.
For some time, researchers, using
fairly coarse rock dust (the only kind available to them) have tried
to justify the remineralization of the soil with rock dust. The
question now is no longer whether to re-mineralize, but where
to get the best universal rock dust.
Agrowinn Fertilizers and Soil
Amendments are environmentally friendly and will not leach into
your ground water. These products do not contain excessively
high concentrations of
Nitrogen, Potassium, and/or Phosphorus, and are more efficient.
They are the best organic products you can buy.
