The Pour-Through Extraction Procedure: A Nutrient Management Technique for Nurseries

As part of your quality control and fertilization program, nurseries should regularly check the pH and EC (electrical conductivity) of stock grown in pots. Knowing these numbers helps you diagnose the level and availability of nutrients to the plants. You can save money by fertilizing as needed rather than on set schedule.

NCSU has just released a new publication which outlines the steps of the Pour-Through Extraction Method (opens as a pdf) to measure soil EC and pH. This technique is easy to learn and should be part of your regular routine.

Need help learning the method? Would you like an on-site demonstration of how to properly use ec/pH meters or pens? If so, please contact me and I would be happy to arrange a visit to your nursery.
