As I’m rounding up my components for my soil I’m realizing that these two amendments are interchangeable, and the line is a fraction of the price. My dilemma is that the lime is equivalent to 87.5% of calcium carbonate (aragonite), and aragonite itself is 33% CaCO. So my math, which is bad and rough, says you need 1 2/3 lbs aragonite for every lb of calcitic lime. Does that math add up to anyone? Also is there a formula that’s easy, rather than me fumbling through the math files in my head from childhood.
