As the heading says does anyone add boron to their soil? If so how, and how much? Mainly thinking about in the vegie garden. I've been reading at lot about boron deficiency lately. Some people clam it is a major cause of arthritis. Australia is one of those places that is on the whole deficient. My soil test said my land was boron deficient and nothing needed to be done about it. The soil test i had done was done by an independent company that is supposed to be the best in Oz, but I found some of its comments strange. Boron, magnesium were both low and the comment was don't worry about it.
