Agronomic Services — Soilless Media Analysis

Kristin A. Hicks, Ph.D., section chief

Media analysis (using the saturated media extract procedure) helps growers fine-tune their fertilization programs for container crops grown in soilless media by enabling them to monitor changes in electrical conductivity, pH and nutrient levels.

Standard analysis includes: nitrate-nitrogen, ammonium-nitrogen, urea, phosphorus, potassium, calcium, magnesium, sulfur, iron, zinc, manganese, copper, boron, sodium, chloride, pH, electrical conductivity/soluble salts.

Standard fee per sample:

*NC growers $5

*NC researchers $12

Non-NC growers or researchers $25

*Samples qualify for the in-state rate if they originated in North Carolina.Research samples require an annual research agreement prior to submission. All research samples receive a 10% analysis recheck for quality control at no added cost.
