Monitoring Nutrients in Large Nursery Containers

Using suction-cup lysimeters is a good way to extract the substrate solution from large containers when electrical conductivity, pH, and nutrient analyses are needed. A lysimeter, a soil water sampler, consists of a tube connected to a porous ceramic tip that is inserted into the container so that the tip rests on the bottom of the container. Lysimeters should be installed for the whole course of a growing season in large containers.
