Abstract

Abstract

The ability of reclaimed natively high B soils to re-establish elevated soluble B concentrations has been termed “boron regeneration”. Potential mechanisms for this phenomenon were qualitatively examined. Soil samples reclaimed in columns contained appreciable concentrations of residual, potentially reactive B and Cl. Reclamation by multiple batch extraction removed 100 percent of the Cl; however, the soils could not be completely reclaimed of B. Boron regeneration was observed in both column and batch reclamation systems, while Cl regeneration occurred only in the column systems. The data suggest that two mechanisms may account for B regeneration. Post-reclamation release of B from residual sparingly soluble or desorbable B-containing sources is confirmed by the batch and column experimental results. The column data suggest that portions of the soil were bypassed by the leaching solution during reclamation. By analogy with Cl behavior, post-reclamation diffusion of B from bypassed to leachable pores also contributes to the B regeneration phenomena.
