Water/Fertilizer
Analysis
Our Water and Fertilizer testing allows you to see what your current nutrient levels are, whether that’s in your source water, fertilizer solution, or runoff.
We will test for: pH, Soluble Salts, Total Alkalinity, Total Nitrogen, Nitrate Nitrogen, Ammonium Nitrogen, Urea Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, Sulfur, Iron, Manganese, Copper, Boron, Zinc, Molybdenum, Aluminum, Sodium, and Chlorides. Silica and Fluoride are available upon request (though this may add a day or two to turnaround time).
Water and Fertilizer analysis is $46 per sample. Silica and Fluoride can be added for an additional fee ($10 for Silica and $20 for Fluoride per sample). Typical turnaround time is 1-3 business days.

Concentrated
Stock Solution
Sample prepared to determine nutrient concentration of solutions greater than or equal to 0.5% or 500 ppm of any individual element or Nitrogen-containing component and/or having an EC greater than 5mS/cm.
Please note on the submission form if this is a concentrated solutions as this will require the lab to dilute the sample prior to analysis.
If you are unsure, please note this on your submission form so that the lab can check prior to logging the sample and avoid any potential delays in processing.
Concentrated stock analysis is $56 per sample and Silica can be added for an additional $10 per sample. Typical turnaround time is 1-3 business days.
