Re: Representative chemical species in soil solutions
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!
Re: Representative chemical species in soil solutions
I still like the KISS chart better....

David...
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......

Re: Representative chemical species in soil solutions
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!
Re: Representative chemical species in soil solutions
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. 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!
