Abstract
Interaction of effluent dissolved organic matter (DOM) with native soil organic matter (OM), B complexation with DOM, and adsorption of B by soil all play an important role in assessing B transport in soil. However, no information is available yet on the impact of these reactions on B mobility in soil. The objective of the present study was to evaluate the effect of B‐DOM complexation on B mobility in soils irrigated with treated effluents. Soil column displacement experiments were conducted to measure the B mobility in the presence of DOM extracted from municipal treated sewage plants. To describe B transport in the presence of DOM, a traditional multicomponent transport model was used. The model took into account the B‐DOM‐soil reactions (obtained from batch experiments). It was observed that the presence of OM molecules in soil solution enhanced B transport in soil due to B‐OM complexation. The concentration of this complex in soil solution increases with the concentration of the dissolved OM (from both effluent and native soil).The model simulated well the effect of DOM on B transport in soil.
