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.

New book available-Diseases of Herbaceous Perennials

There is a new book available through APS Press titled 'Diseases of Herbaceous Perennials'. The authors are all plant pathologists and include Mark Gleason (Iowa State University), Margery Daughtrey (Cornell University), Ann Chase (Chase Horticultural Research), Gary Moorman (Penn State University) and Darren Mueller (Iowa State University).
The book is full of over 700 color photos and would be a wonderful reference text for growers of perennials (as well as garden centers, horticulturists and Master Gardeners).
You are welcome to stop by the Adams County Extension office and do some browsing before deciding to buy. We also have an extensive resource library for diagnosing plant diseases and insect problems that are available for growers to utilize. Please call ahead to make sure that we're in the office!
