Looking for High Calcium Field Soil

Looking for field soil to grow in that is specifically high in calcium. I was looking at buildasoil but not exactly sure what I am looking for. Any advice?

The nutrients I am using don't have any calcium included, I was thinking gypsum as it should be fastest to get into the soil after application.

I saved a thread by @speedwell68 and am wondering about trying it, calcium chloride. If I try it, I'll dissolve very little in the nutes rather than their approach of a one-time soil treatment.

I'm having some beneficial results with soluble gypsum, but am still unsure about the optimum amount. It appears I need to use more than I am (0.69 g/gal), but dissolved in my nutes and poured through substrate it raises leachate pH beyond my desired target.

Your question also reminded me of this news item (emphasis added):

"For the Maya, the Mirador-Calakmul Karst Basin was the 'Goldilocks Zone,'" study co-author Ross Ensley, a geologist with the Institute for Geological Study of the Maya Lowlands in Houston, told Live Science in an email. "The Maya settled in [this region] because it had the right mix of uplands for settlement and lowlands for agriculture. The uplands provided a source for limestone, their primary building material, and dry land to live on. The lowlands are mostly seasonal swamps, or bajos, which provided space for wetland agriculture as well as organic-rich soil for use in terraced agriculture."
That leads to terra preta, a dark rather than light soil.

calmag+ xanthan gum produces a calcium chloride hydrogel. I use this outside in my sandy acidic loam, with some 10-10-10 and a pile of leaves.
Applied to compost leaf, NPK nutes or biochar, it makes a time release fertilizer, holds water in the soil and releases it slowly.

Xanthan or guar gum polysacharrides have to be pre mixed with iron or calcium, or it will strip it out of the soil.

Dang, I just looked up the label and there is indeed no calcium listed on it. Weird. I know in the normal 321 formula, the "2" is calcium nitrate, and the base nutes have pretty low N. Not sure I would use calcium nitrate if the base is already 18% N tho...

You could always call or email JR Peters and ask what they recommend...

I am waiting for a reply now. They specifically said not to use the part b or there 2nd part to supplement for calcium in the outdoor version. I am wondering if my source water will have enough calcium. Planning to use normal tap water.

That's kind of shocking, but depends on your water source, I guess.
Good info to know about the 321 Outdoor.

Not a joke but didn’t you say it doesn’t have calcium? Its jacks why not just use one that does.
