MICRONIZED CALCITIC LIME that goes through irrigation systems. CAL106

I've used many forms of calcium. Calcium hydroxide or hydrated lime was fairly soluble.
It's only drawback is that it's very caustic and will drive your pH to 12 in a hurry so do
constant pH tests until you figure the right amount to use. Some saltwater or marine
aquarium people use it to ensure pH and calcium levels are high enough for coral growth.
It's sold under the name Kalwasser for that purpose.

Watch and learn.

The response everyone is seeing can't be from just the micronized Calcium side of the calcium carbonate molecule. This is in a super fine powder and the complete molecule still remains intact. Most specifically the CO3. Which when degraded breaks into literally a CO2 inside the root or leaf surface. Pretty sure this is a big part of what we are seeing. This free Carbon is priceless and has a big old fat Calcium hanging there. People applying 2 grams per gallon are saying they see results!

The problem with calcium carbonate is when it's mixed with pure water that has alkalinity, the alkalinity makes the calcium bond stronger. It doesn't matter what size the particle is. The smaller particle will help get down irrigation lines, but if the alkalinity is in the water, it won't make any difference. What makes calcium carbonate soluble is Hydrogen in the right ratio. 😎

Here in Peru we have world record yields in many crops with alkaline water. Not sure what you are stuck on. Roots exude organic and amino acids at the rhizosphere level. Some crops like blueberries don't like that. Even so, Peru is the number 1 exporter of blueberries, so guess everyone must have figured that out. And we still lay on quantities of gypsum and yet, still see great response applying small quantities of CaCO3 that are micronized, not solubilized. Big difference.
 
The problem with calcium carbonate is:
It destroys thiamine, riboflavin, sulfur bearing aminos, and methyl/acetyl compounds. Surely I have or will leave a post on methylation somewhere?

"Oh you grow 'natural' organic bud? Oh... you use bone meal? Wood ash? Limestone? Worm casts? Crab shells? Coral reef? Tap water? No thanks, I'm good. I only smoke unleavened weed. "

The pH of the solution has a profound effect on whether these ions exist as carbonate or bicarbonate. The figure above shows how the proportion of these ions varies with solution pH. The pH would have to be above 8.3 to have 1 percent carbonate. Therefore in fertilizer chemistry, there is no chance for carbonate to exist in our water. Any carbonate picks up an extra hydrogen proton and converts itself into bicarbonate. So, bicarbonate is the ion we should be quantifying when working with fertilizer chemistry:

Carbonate has a -2 charge while bicarbonate has a -1 charge due to the extra hydrogen proton. When we deal with fertigation chemistry, we are actually working with ‘equivalents’ which is equal to the weight of the molecule divided by its electrical charge. The molecular weight of carbonate is 60 grams and bicarbonate is 61 grams. Dividing by their electrical charge results in 30 grams per equivalent for carbonate and 61 grams per equivalent for bicarbonate. So you can see that there is almost a 2 to 1 difference in their equivalents. A little carbonate ends up going a long way to neutralize the carboxylic acids we are attempting to synthesize. I imagine some Blueberries taste like blueberries and some taste "earthy".

Here is a great one regarding yields and carbonates. Sure seems in line with Doc Tiedjens. So many folks are afraid of carbonates. Really depends on what you are sitting in and what plant you are growing. Applying any Calcium source is a big responsibility as many existing "unseen" deficiencies all of a sudden show up!
