I only have OS in one spot -- in mostly calcareous soil. Haven't tried it on the non-mulched lot yet. OS on my calcareous, mostly unmulched soil presumably gets plenty of calcium, but it still lacks the orangey punch of the LZ.
I'm still learning the effects of Ca, but LZ is one of the few that I have in both lots (mulched with low ca and unmulched with higher ca). The LZ in the mulched / low ca lot is mild in flavor, like the OS, unless I load it up with gypsum.
I think a lot of the FL mangoes require lots of Ca to get the flavor profile that we appreciate here. So, shipping LZ budwood to a region with acid soil and low Ca would probably result in bland fruits. My family has an LZ tree in El Salvador that I haven't tried fruits from yet, but the tree's owner didn't seem all that impressed with the flavor, same with Carrie, which I believe needs a lot of Ca to get its characteristically delicious flavor.
LZ is better tasting if it gets enough calcium.
Have you found this the caae with OS? Wont calcium (in the right amounts) improve all mangoes?
