A study was conducted to develop and demonstrate a practical and accurate method of applying the Pour-Through nutrient extraction procedure to bedding flats and plug trays. The Pour-Through technique involves pouring a known volume of water on previously saturated medium, and collecting the leachate which is pushed out the bottom of the container. The volume of applied water necessary to conduct a bedding flat or plug tray Pour-Through was determined based on leachate pH and conductivity. The sensitivity of the Pour-Through technique when applied to bedding flats and plug trays was determined using varying rates of lime incorporated media and fertilizer. The leachate was analyzed for pH and conductivity. Results indicate that the technique can be used effectively on bedding flats and plug trays.
