if the actual amount of Iron in the soil is there but not readily available because of the soil pH 5.6 is plenty low for iron availability. Unless, of course, you're saying it's too low. In that case I would say, the pH can't get too low for iron availability. The more acid the soil is, the more available iron is. Period. No exceptions. The amount of Fe was .7 ppm and it is a measure of how much Fe is actually in the soil, independent of pH and its affect on availability. Kind of, but not entirely true. That's the amount of iron in the soil that is detectable based on whatever extraction they ran (which isn't given). The amount of iron they can detect will vary depending on how it was extracted. If they measured the iron in saturated media extract, the detectable amount will be lower than if they extracted it via mehlich 3 or DTPA, which will be lower than if they extracted it via quadruple ammonium acetate, etc. Some of the iron may still be on the exchange and some may be in less soluble forms and could become available if chemistry conditions change.

For some reason, I can't post a comment to your message, so I'm starting another thread. A 1/2" shower door may be very heavy, so consider 3/8" for the door, while keeping the fixed panels 1/2". You really won't notice the difference in depth for the door. I'm speaking from experience.

Total price over $7500, straight corner, door plus two shorter panels (door is on 5' side and attached to wall). Classic L-shaped installation. Invoice doesn't even specify door size, so I suspect it is standard 28", but I will ask. Hate quotes without decent breakdowns, so I'm unhappy already. I don't think DH is up for DIYing this. It's part of a whole house remodel and addition, so we're overwhelmed with projects and need to get this bath done. How much do clips cost? Also, we have hard water and calacatta tile in the shower, so both low iron and good coating are a must, even though I know they are adding some to the cost. Still, 1/2" Starphire for fish tanks sells for $15 a square!

In my unusual installation adventure last year, I noticed that the price was about double or close to it. I ended up with a totally free low iron french door shower enclosure. Millworkman was very helpful in problem solving some issues with my glass. THANKS! If I had another room to do I'd consider the regular glass as an option. It really depends on the colors in the room. I have blues and greens in my bathrooms and the regular glass would go with it just fine IMHO.
