The Langmuir adsorption equation was found to describe the adsorption of boron from solution by three soils up to a limited concentration. Agreement for a fourth soil was not as good. Wetting and drying of the soil following the addition of B waters increased the maximum adsorption capacity and bonding energy of the soil for B. Leaching and successive extraction experiments indicated a relationship between the bonding energy of the soils for B and their release characteristics. Boron removal from three soils indicated a desorption type of release, whereas release by a fourth soil appears similar to the formation of a saturated solution of a chemical compound. These findings indicate that the difference in the release patterns may be expected to affect the absorption of B by plants and the removal of B from the soil.
