Re: Spacklerstyle 2021 Soil Test
Awesome. Thank you both for the extra time teaching here. It’s really helping me put it together!
I really appreciate it. This stuff fascinates me, and I really enjoyed my chemistry classes... I just can’t remember 95% of it... ha!

Re: Spacklerstyle 2021 Soil Test
It depends on what gets reinforced over time. I use a lot of hydroxide chemistry because I'm a soap maker as a hobby.
Chelated iron is already bound such that the plant can access it, often to a humate or the like. The root can break the bond. But in a pH too high, it'll simply get ripped away from the chelate and bond as rust or a hydroxide. Your pH is high enough to do that almost instantly. Mine is low enough that chelates aren't needed. There's a trim band of pH where chelates are required.

Re: Spacklerstyle 2021 Soil Test
Most of the chelated iron you'll see for sale is EDTA chelated iron. That won't do any good at your ph. There's another form (EDDHA) thaat can help. But it's extremely expensive. I've used it in targeted applications to try to help an individual plant, but I wouldn't consider it for a lawn. A foliar application of soluble iron would be more effective and it wouldn't need to be chelated.

Thanks Green. I’ve researched EDDHA and came to the same conclusion! Interestingly, Milorganite seems to do pretty well for color by itself. I didn’t even need to use foliar FAS apps last year. I’ve really just more courteous about what’s going on and why. These explanations are pulling it all together for me.
Love this site and everyone’s knowledge/expertise.

Re: Spacklerstyle 2021 Soil Test
Yeah, you can chelate the ion such that it will work, but it's too expensive for large areas (but can work in a pot or very small area if necessary).
Spraying can work, but it's not like the grass will go into chlorosis. Probably. Bermuda's pretty tolerant of this sort of thing.
Right now, I'm brushing up on resin's polymer bonds. I'm making pens for Easter for my mother and my female friends. Photos soon, although they're not terribly impressive, just fun.
