Abstract
This project investigated the retention of
phosphorus and clay in 5m (wide) x 10m (deep) plots
located in streamside management zones in commercial
timber to which simulated runoff was applied from a
tank and dispenser system. The purpose of the project
was to quantify the filtering/adsorption benefits of
SMZs with respect to phosphorus and clay. Plots were
located on five slopes ranging from 2%-20% and either
had an undisturbed forest floor or had the forest floor
removed. Surface water samples were collected at 0, 2,
4, 6, and 10 meters within the SMZ during a 1-hour
runoff simulation and analyzed for total phosphorus
concentrations.
