These pictures are from a system that I am cycling. The water's pH is 8.2-8.5. The seedlings are less than two weeks old and have received nothing but system water. It's been cold and foggy here for…Continue

What do you want most in all the world? More money, a new car stereo, a vacation? To lose ten pounds, to get home from work in time to see your favorite sitcom? Or is it something more than that, something harder to define?
Maybe you've given up on ever realizing your true dreams, and you settle for smaller things because they, at least, seem possible. Maybe it never occured to you to ask yourself if the goals you've been pursuing really are what you want…Continue

Here's an exercise to try at home. You will need a working stopwatch, or another timepiece that measures seconds. Before you begin, seat yourself in a comfortable chair and loosen your clothing.
Watch the second hand as it passes around the face of the clock. Picture the moment of your death, perhaps many decades in the future, or perhaps only a few years or months (who can know?). Wait for the second hand to reach the starting point at the top of the…Continue

Well it seems like I’ve been having the same/similar conversation here in the village with a lot of folks lately that goes something like this…
“Gee Vlad how did you know dot…dot…dot…”
“Well, I read it in a good book/study on the topic” (and if applicable, tried it out to see for myself).
“Ooh, I don’t have time to read”!
“Do you watch T.V”
“Yeah, who doesn’t”?
“Well, if you…Continue

Hi Vlad, thank you for text me. Let me know which microbiological fertilizers you are registering now
i have read all your posts',and it is as reading my own Thoughts.
six mounth ago i left my job trying to do things that i like (carpentry, pottry, etc)
creating for my soul,
and AP system to fead me.feelig that small comertial AP can provide some small income to make me go around .
and today i have come across your post ,and your picters and i can see you are doing AP comertial (corect me if iam mistaken) i would like to ask you for some of your Know how if you are willing to shere
thank you uri
Hi Vlad, long time no talk. How and what are you doing these days? How is your operation going? I have had a pretty busy and exciting year building a new farm. One thing I'd like to share is my use of charcoal as media in my fishless system and in raised beds. What do you think about this, off the top of your head? I'm interested in your opinion.
Hope everything is well and you enjoyed a warm holiday season surrounded by friends and family.
You know, there's an entire side of your face that I never knew existed....until this weekend O_o
bolje vas nasao!
Ja sam totalni pocetnik u akvaponici, trenutno gradim svoj prvi sistem i ucim ucim ucim o svemu ovome :D
This is a section of an essay I'm writing about soil. The very last sentence describes how the pH is kept in check during the nitrification process.
I'd like to
1. more accurately describe both the nitrification chemistry math of NH4+ conversion to NO2- and NO3-
as well as the
2. denitrification math involving the hydrogen and oxygen from the NO2 and NO3- in which the N2 is returned to the atmosphere through denitrifying bacteria.
3. It also seems that the plant exchange of H+ for nitrogen would help the soil retain a higher pH. Can you help me verify that, and the correct symbol for the form of nitrogen being exchaged?
Maybe a new discussion would be best, but I wanted to specifically ask for your help so I posted my question here.
Bacteria come in two basic types. Anaerobic which lives without oxygen and produces offensive odors, and aerobic which lives with oxygen and produces pleasant fresh odors. Bacteria are responsible for recycling carbon, sulfur, and nitrogen. CO2 is a by product of aerobic bacteria, and sulfur is recycled by anaerobic bacteria. Nitrogen found in the atmosphere can not be used directly by plants. It must be 'fixed' through a process called nitrification where aerobic bacteria combine nitrogen with either oxygen or hydrogen to form nitrite (NO2-), and eventually nitrate (NO3-) ions from the ammonium (NH4+) waste of protozoa and nematodes which consume other bacteria and fungi. Nitrification produces an acidic pH when oxidation occurs. This process is called reduction because there is a loss of electrons, and it releases energy that is used by the bacteria. Nitrifying bacteria do not generally like low pH, but fortunately other bacteria called denitrifying bacteria convert nitrogen salts created by the nitrification process back into nitrogen N2 which returns to the atmosphere.
The plants exchange hydrogen (H+) for nitrogen (N?) which also helps to return the pH to a higher level.
Hvala Vlado !
