Agronomic Services — Solution Analysis

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

Solution analysis is useful for monitoring surface-water and groundwater quality for such varied agricultural purposes as irrigation, fertilization (nutrient solutions), livestock and poultry production, pesticide preparation, pond management and aquaculture.

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

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.
