Hello Johnathan, all my recent tests have boron at .5- .8ppm. I have recently added more in my garden beds and I’m about to add boron to the fruit tree areas as our mangoes, avocados and lychee will soon be blooming.

As for the lime being measured on the soil test but not actually on an exchange site I’m sure that is happening to a degree. I have read where excess lime can give false CEC values. Over inflate them. How much it is actually over inflating I don’t know. I’m sure it’s part of the answer to this issue. It does seem to me that any lime I have used down here reacts super fast, so does sulfur. The pH moves after application very quickly. Some of the soils I have do have chunks of limestone in them from when they dug the dirt out of the swamp 20 years ago. They dug into limestone hardpan and some gets mixed in. This isn’t the case in all of the truck loads I’ve received but some. Some loads will have calcium under 1000ppm and others around 1600-1800, possibly 2000 in some cases.
