Potatoes use $1k of fertilizer per acre, lots of nitrogen.

Also Calcium - Ca  which is what I think is in  CARBON™CA -"Potatoes thrive in calcium-rich soil, this helps produce large full flavour potatoes."

It's possible that CA is for calcium if you look at this. https://www.agritecint.com/liquid-fertilizer-wheat-crops/ Soil with lots of hydrogen will naturally be more acidic. Acidic soil prevents nutrients from going into the plant and thereby decreases plant productivity. To combat this, liquid calcium actually displaces, or moves, the hydrogen out of the way, allowing more nutrients to

Potatoes aren't a broadacre crop, but grains are if you read the article below, and the nr says PK and CA are for broadacre crops.  The first PK nr listed 4 grains that  PLAN is doing greenhouse trials on.   PK are phosphorus and potassium.  "CARBON PK is PLAN's first broadacre fertilizer so for sure CA is a calcium fertilizer additive.  .
