This test is conducted at our lab that was severely damaged in the tornado of December 2021. The test will be offered when the lab is rebuilt.

Plant tissue testing can provide insight to plant nutrient deficiencies that may occur during various growth stages.
Your report will show the amount of Nitrogen, Phosphorus, Potassium, Magnesium, Calcium, Zinc, Copper, Boron, Manganese, Sulfur and Iron.

Obtaining a Sample

Containers for your samples are available at your county extension office.

Please carefully follow the instructions in Sampling Plant Tissue for Nutrient Analysis (AGR-92)

Avoid contaminating plant material with excess soil or dust as these particles will elevate the iron & manganese levels in your analysis.
Avoid submitting dead or dying plants.
Collect a “softball size” or 20-25 leaves (except tobacco where only one leaf is required).
Use a paper bag or cardboard box. Do not use plastic!
The specimens should be taken at random locations and be representative of the field at large.
