We just went over this in class and I said, "BY GOD, WHY HAVEN'T I COME ACROSS THIS INFORMATION BEFORE?!??" It makes so much more sense and helps us who are pioneers better design our systems (instead of that simple chart with the pH and the nutrients on a scale). ENJOY! :ugeek:

I still like the KISS chart better....

David... :lol:

IDK, I wish I had this information earlier this year. The water chemistry in AP systems are too complicated to understand from that chart, and that chart is not ALWAYS right and the table above starts to show you that... but, meh, the simple chart is good too!

It's a shame, that there is no one that can make a graph that is right...... :?

Well, I guess technically it could be right if it was titled "General Availability of Nutrients at Varying pH" because the title would in itself suggest it's not always right! :-D

That chart was originally from hydroponics field which use as nutrients inorganic salts, while the majority of our nutes are organic and readily available to the plants. Nutrient defieciencies we experience are because the nutrients aren't present or if present precipitate out of solution quickly. IMHO

No, in nature certain nutrients are almost always inorganic when available to the plant and must be inorganic to be available to the plant. :mrgreen: Oh these classes are eye opening!

For example potassium.

TV, the media, marketing and advertising campaigns from food companies, have sold us on these "organic" concepts that are incorrect except from a fundamentally philosophical perspective that promotes sustainability. I'm not sure why I didn't realize that before... I kinda just bought into it as well, but that's what life is for live and learn! :-D

Hmmmm.....I wonder where all that K in Maxicrop comes from? 1-0-4

I did say IMHO.

:-D no problem I'm just sharing buddy! This is all new to me and it's a TON of information. My head is SPINNING!!!!!

That was a challenge UF...... :idea:


Well, I guess technically it could be right if.......
That's a response I'd expect from the 'rulership' in DC.... :roll:

I see a class project in the making UF...... :P :lol:

the problem in "research" the research is always done from the researcher's perspective, application, or motivational force. oh i forgot the part about needing to get a degree. :D

Well, that's why at the County Extension we only use research to show residents from sources that are "unbias" in other words public Universities, certain non-profit organizations, etc.

You definitely don't NEED a degree to do research. Look through the posted journals at "Aquaponics Journal" you'll see some of the guys that do and publish research don't have a relevant degree!!! What a perfect example... :lol: :lol: :lol:

Rooftop Aquaponics in Jerusalem
Researchers Tim Evans (M.A. Development Studies), Kyle Petrie (B.A. Agricultural Science) and Chris Somerville (B.A. Natural sciences; M.A Development Studies)...
Okay, so ONE guy has a agricultural degree, but not only is it undergrad (in other words limited in scope and depth), but he formally knows nothing about aquaculture and soil and water science!!! The other 2 guys know nothing as far as the science of aquaponics! So you see, research is for everyone!

Seasalt is 30% sodium and only 1% potasium...wasn't there a thread on salt water aquaponics? :lol:
