BORON This is what I've learned by studying boron. It's a unique micro in that it doesn't bind to other "stuff" in soil. It's so free that rain and watering can flush it out of the soil. It's huge role is in the formation of the "meristem". Meristematic cells are the undifferentiated cells that go on to form all specialized cells in any plant. The specialized cells are in the vine tip, in both female and male flowers, in the seed formation and the growth of the fruit.
Once B gets into a cell it's locked in. It's an immobile micro. Since it is needed throughout plant growth, flower formation and fruit formation, it must be made available constantly from transplant to harvest. In the soil B can go from enough to not enough in a matter of days!
Most lab reports will suggest that a range between 0.8 to 1.2 ppm is adequate. That may be true if that amount is present in the soil every day but it's such a low amount it could deplete very fast and BINGO!...no growth. I started going to higher B levels after a grower (the Boron Moron lol) accidentatty miscalculated her amendments and added 3 times the "suggested" amount. She had her best year. Many growers I've talked to, are aiming for between 4 ppm to 6 ppm. My 4 best years have been at that level with my highest level being 7.43 ppm on my PB last year. I get a soil test done every month and know where my nutients levels are. Borax is used in the spring amendments and Solubor dissolved in water is applied through drip irrigation and added throughout the growing season. Please use the comments section to post any corrections to my discussion. Boron is important!
