Send another sample in and see how the bases have moved.
Thanks the compost def seems like it has high salts so I think its from there. I use ro water other amendments are top quality, gypsum is down to earth brand. My rockdust is basalt so I think that's straight.
I hope this flushing helped Im going to send another sample in a few weeks and see if the Na left. Then at the end of the round Im going to cut this mix and send that in for a test. Thank you for the help.
I bought this seagreen product for the flush. I guess it was orginally called desalinator plus or something. I legit think these type of product are bullshit but a couple of my plants were pissed off about being transplant for a week now and they all perked up after watering with this seagreen a couple hour after even the plant I flushed looked happier than ever.
Im researching it and the created said this,
"I have no problem responding to your question. No-till farming was intended to be something that was done outside where there were seasonal rains that washed away excess ions, namely sodium. The problem I've noticed with some indoor, or container garden, no-till farmers is that there is no runoff ever, while organic matter top dresses are continually applied. Even though the inputs are organic, many are marine based such as seabird guano or fish meal, or kelp meal, all of which may have rather high amounts of naturally occurring sodium. If the container is never watered to excess the sodium will never leave the system and will build up. The excess sodium displaces other beneficial cations, and even may cause chlorosis or necrosis. Also bacteria themselves are creating acids which are bringing into solution the required plant nutrients, but after a certain amount of runs these acids build up and create acidic soil conditions unless regular liming occurs.
When we mentioned that it can alleviate some of the harmful conditions that may arise out of no-till farming we are referring specifically to excess sodium. Sea Green contains halotrophic and chemotrophic bacteria which will immobilize sodium ions and buffer them from the rhizosphere. It's not a permanent fix but it will work pretty well for a long while.
Of course both of these issues can be alleviated through periodic flushing as if it were a winter rain. Though most indoor or container no-till farmers I have encountered do not incorporate such a practice into their regimen.
I hope this sheds light on to why that statement was made. We are big fans of Masanobu Fukuoka and respect no till farming very much."
