The properties of adsorption-desorption, adsorption heat, and hysteretic desorption of boron effected by temperature in brown-red soil (9701), yellow-brown soil (9702), and calcareous alluvial soil (9703) collected in Hubei Province of China have been studied. The results showed that the adsorbed boron was more in 25℃ than that in 40℃,r. e., boron adsorption reaction was exothermic. The boron adsorption heat of 9701, 9702, and 9703 calculated with equilibrium constant of the Langmuir adsorption equation in 25℃ (K₁) and 40℃ (K₂) were -16.4,-15.6, and -22.6kJ/moL, respectively. These values were within the range of chemical adsorption heat, and it was testified in thermodynamics that boron adsorption in soil is mainly a kind of chemical specific adsorption. In comparison with 25℃,that hysteretic desorption of boron in the experimental soils was higher in 40℃,the hysteretic coefficients of boron of 9701, 9702, and 9703 were enhanced to 67%, 21%, and 62%, respectively. Being corresponding with the properties of soil boron adsorption-desorption, the desorption ratio of added boron of 9701, 9702, and 9703 in the summer were lowed by 38%,19%, and 7% than in the spring, respectively. These may explain that lack of soil boron in the summer was caused by increase of boron hysteretic desoiption in soil in higher not by decrease of boron adsorption in soil.
