Humus composition in the loamy sand soddy-podzolic soil limed with waste lime

The humus composition in loamy sand soddy-podzolic soil, as well as its transformation under the impact of chemical reclamation with waste lime, has been studied. The optical density of humic acids was measured before and after liming. It was found that the HA1 fractions differ in the capacity to retain alkaline-earth metals. Special investigations of the type and strength of the lime strontium fixation in the soil adsorbing complex should be performed with the intention of using it safely.
