CORRECTION: I stated that you could soil apply Solubor at 50 lbs/acre, when I should have stated Borax, which is approximately 10.5% boron (Solubor is 20%), and added the pounds of actual boron/acre.  The corrected sentences now read: 

"Major boron deficiencies can be corrected via a soil application (major deficiencies would be far below the critical value).  In both almonds and pistachios, broadcast 25 to 50 lbs of Borax per acre (about 2-4 lbs of actual boron). Make sure to take into account soil texture: lighter textured soils should have lower rates of application."
