Aquaponics has got many issues since 2003 when introduced to agriculture industry .
At that time Dr. Rakocy, professor of University of Virgin Islands introduced the successful commercial aquaponics system for the first time.
In fact many agriculture specialists already accepted aquaponics in mind for the good eco-friendly agriculture.
However, they can not agree to the aquaponics in public. How come they are forced to do so:
The principle of agriculture: The basic elements of fertilizer : Nitrogen, Phosphorus, Kalium(Potassium)
and the other 13 minerals including 3 basic elements. The principle is inevitable for growing plants by
people of Agriculture. It has been accepted and generalized by all agriculture farmers and specialist over the
world for generations. This principle shall not be variable and fixed one otherwise they can not develop
smart-farm via ICT extending to the 4th agriculture revolution: automatic farm operation with less man-powder.
Nowadays agriculture industry has got the problem with the productivity: They can not increase productivity
of crops with the principle of fertilizers. As the fertilizer blending ratio per plant is all same over the
world. Therefore they are looking for automatic operation method and developed "smart-farm" with various
sensors detecting the major elements of fertilizerand supplying the necessary amount of fertilzer to plants
automatically. So the hydroponics system came out with the principle of fertilizer as the best agriculture method.
The costs is very higher. Ordinary farmers can not be afford to the system.
On the contrary aquaponics is not related with the principle of fertilizers as we do not use any fertilizer and
pesticide at all. In aquaponics the plants can get the natural fertilizer from the fish waste via the natural nitrifying
bacteria came from the air. The natural fertilizer made by the bacteria with fish waste is estimated "quite small amount"
and it is enough for growing the plants in reality from my experience - This is why most of agriculture specialists
can not accept. They argued the plants can grow with such a small amount of fertilizer made by the bacteria
with fish waste.
They claimed that the nitrate shall be min. 200PPM for growing the plants practically. However, in aquaponics
the natural fertilizer is around 20PPM in amount, with which the plants can grow well in fact contrary to the
principle of fertilizer.
That is why SamKay's aquaponics is based on nature farming. Like the plants in the mountain, there are no farmers
in the mountain and can not give fertilizers and pesticides. But there are many quality crops harvested.
You can remember the dried leaves in the mountains. They make the smoothie like a little tannin pleasant smell to our
nose. However, the vegetable and lettuce grown with the fertilizer look very good quality in appearance.
In fact when they are stored in the refrigerator, the freshness can not maintain for a week and first fungus appears and
rotten soonest. This is caused by use of fertilizers. What is worse, many agriculture specialists still emphasized the use
of fertilizers. Whereas the freshness of vegetables/lettuce grown via aquaponics last longer and become dried up only
by loosing the moisture instead of being rotten.
For the past 8 years experience of my studying aquaponics and growing plants I found the fact that we must get back to the
nature. We must follow the nature principle in agriculture. Aquaponics is the first step toward the nature farming.
SamKay is pursuing the nature farming via aquaponics.
Now I can say Samkay is one of pioneers of aquaponics and for the first time SamKay only pursuing the nature farming
via aquaponics and the theory is patent pending.
The only way that you can get your agriculture people understood aquaponics is to hold the seminar in Egypt
I am always ready to go there at your convenient time upon your request.
