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.

Cheers

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.

My tilapia are coming in a half hour. 10:30am Central Time. Yeah, I wasn't sure if the website actually hosted the videos like it does the pictures, or if it just linked to them, so I tried to upload straight from my computer. Anyway, it won't let me delete the video, at least, not that I can tell. Kinda embarrassing :) I'll load it up to youtube, its just the video version of my pictures.

Lol well thanks for accepting the request!!!! Yes of course I can tell you anything you wanna know about our program. We have a website www.belovedcommunitychicago.org which is currently being updated so the new website will be www.thebelovedcommunitychicago.org. Our urban farm project went from a small summer project to a year round thing lol so we are trying to put up all of the info/pics of the work that the kids have done throughout the summer and fall. I can gladly email some photos of the urban farm if you'd like. The kids are really excited about the aquaponics system they are anxious to start lol.

Ha. CMH for camera. Deal.  I posted the pic here:

http://community.theaquaponicsource.com/group/californiaaquaponics/forum/topics/santa-cruz-area-ap-tour-august-18th-and-25th

Can you join us this weekend?

Yes, that was my first steelhead, on my first attempt at fly fishing on the Klamath river last year. Hope to return this year. I'm a fairly regular ocean fisherman, and I love to freedive and shoot big fricken fish, but lakes and streams are new territory. BTW, I'm going out for albacore next week, hope to spear a few. My buddy went out on Saturday and saw a school of 50 plus albacore just lounging under the boat.  Woohoo, can't wait.

I just got some fry and small fingerlings, do you think it will be ok if I put them with some 2" mosquito fish?

Hey buddy, long time. Hows life? Hope all is well, I've been crazy busy. Too much work but still hardly any income...still. But the future looks crazy bright too. Hope to hear from ya.

Cheers

Hi Vlad, honored to have you join the Sacramento Aquaponics Group.  Your home is definitely the most distant part of the Sacramento region of anyone in the group!

LMAO!  I'd love to be a fly on the wall during that conversation with your wife.

Hi Vlad

Have been running low ph for a long time and find that the bio filter changes and will still work plus plants like

this low ph was done over a long period

this is using tilapia

also there is a government greenhouse operation in Canada that has done the same as I have

Have been able to breed tilapia at very low ph with good success

Thanks for the friend request Vlad!  I didn't realize we weren't already friends.  :)
