Laboratory methods are presented for determining the amounts of boron that must be leached from soils to reduce their soluble boron concentrations to nontoxic levels. One method consists of an extraction of a soil sample with a 0.01 M mannitol −0.01 M CaCl 2 solution. The second method consists of dialysis of a soil sample against a boron‐specific resin in the presence of 0.01 M CaCl 2 solution. Some of the soils studied were observed to “regenerate” toxic levels of soluble boron following reclamation.
