| Abstract: | To determine boundary effects on leaching, we investigated (1) how filter materials affect the concentrations of dissolved organic carbon (DOC) and nitrate (NO3‐N) in soil percolates and (2) whether ion exchange resins and suction plates are equally suited to capture NO3‐N. DOC leaching was higher with PE suction plates and plate material did not affect NO3‐N leachate concentrations. Cumulative NO3‐N leaching was similar for glass suction plates and ion exchange resins. |
