Soil Testing (please note price increase as of January 2, 2017)


​ The Plus soil test includes pH, (Mehlich 1 Extractable) phosphorus, potassium, calcium, mangnesium, zinc, manganese, iron, copper, sodium and boron for $15.00. Pre-sidedress nitrate (PSNT), Sulfate Sulfur (NH4OAc), organic matter and soluble salts are also offered at additional charges.  Soil test nutrients (Plus Test) are extracted using Mehlich 1 and are designed for mineral, inorganic soils thus not suitable for bark or peat-based mixes.  If your growing material is highly organic, a container media analysis is recommended.  The Container Media Test is mainly useful to greenhouse growers in determining fertility of soil-less mixtures. Turnaround is typically 1 to 2 business days (for routine Plus Test) and results are routinely mailed but also accessible by our web application.

Test results are used to formulate research-based, cost effective lime and fertilizer recommendations specific to the type of crop or plant and yield desired. (View a soil sample test report with an explanation of recommendations.) To assist growers with their soil fertility needs, Extension county agents are available statewide to help with any management decisions related to soil test recommendations.
