New equipment in North Carolina agriculture testing lab
Staff Writer |
New equipment at the N.C. Department of Agriculture and Consumer Services Soil Testing lab in Raleigh is helping speed up the time it takes to process soil samples, and is also adding to safer working conditions for employees.

Funding for the upgrades has come from peak-season fees that are charged for soil testing from December through March.
The fee was implemented in 2013 by the N.C. General Assembly with the intent that the receipts would be used by NCDA&CS to make improvements to services offered and to help alleviate testing delays.
Colleen Hudak-Wise, director of the Agronomic Services Division, said upgrades were necessary, and the fees are being reinvested into the lab, which in the end benefits users.
“The peak-season fees have certainly made us sustainable,†Hudak-Wise said. “We were on a shoestring budget and running ourselves ragged trying to keep the equipment operational. This money has helped us replace equipment that wouldn’t have been replaced.â€
Among the new and upgraded equipment are a pH robot, a humic-matter robot, an automated dispensing station, a down-draft table for grinding samples, and an instrument referred to as an ICP that analyzes phosphorous, calcium and potassium.
“The money raised with the peak-season fee has filled a huge need in the lab, and we are grateful to be able to reinvest it in much needed upgrades,†Hudak-Wise said. “We depend on it to replace aging equipment and to hire more highly technical temporary staff.â€
Before the infusion of funds, Hudak-Wise said keeping aging equipment working was a challenge.
“Prior to these new purchases, the last ICP unit we replaced was purchased in 1994. It is hard to deal with something that was just worn out,†she said. “You can’t operate the lab hoping for a good day when all necessary instruments are functional.â€
Moving the lab forward with automated equipment has allowed management to more efficiently use staff, shifting workers to areas where the process can get backlogged, and planning surge weeks with longer hours during peak times to push more samples through the lab.
Automation has also allowed the lab to almost double the volume it processes daily, said Dr. David Hardy, Soil Testing Section chief. The addition of automation is not to replace people, but to improve the efficiency and capacity, he said.
“For several years in the early 2000s, we could process 60 sets with 36 samples per set in an eight-hour day,†Hardy said.
Replacement and addition of equipment with automation have boosted that to 120 sets a day on surge weeks for a nine-hour day, he said, adding the goal is 100 sets during a normal eight-hour day.
Hardy also credits having a creative and motivated staff to help identify critical needs where efficiencies and improvement in ergonomics can be made.
Before the peak-season fee went into effect, the price of equipment limited the ability of the lab to replace it or add additional pieces, Hudak-Wise said. New equipment additions have ranged in price from $60,000 to $110,000. ■
