Nursery Run-Off Pad
The run-off facility was constructed as a means to capture the liquid that runs out of the bottom of containerized plants in order to evaluate fertilizer use. Eighteen lines are set up with microirrigation stakes to precisely irrigate the plants that are a part of the experiment. Below the gravel that the potted containers are sitting on is grooved plastic that captures the liquid that comes through the containers. The captured liquid is sent through a system of pipes into a container at the north end of the facility. After capture, the liquid run off is sampled and checked for nutrient levels with the equipment in our laboratory.
