Soil Testing and Nutrient/pH Amendment Recommendations Information 

Before our office can make a proper soil amendment recommendation to correct deficiencies in nutrients or pH, the land owner/user must take a soil sample. Procedures for this process can be found in the publication, Soil Sampling.

After taking the soil sample, the land owner/user sends it to a laboratory of their choice. Please refer to the publication, Factors to Consider in Selecting a Soil Testing Laboratory.

Upon receipt of the test results, an agent will interpret and make recommendations for soil amendments based on the information provided on the form submitted with the sample.

Please note, if you choose to use another laboratory, you may bring (or email) your results to the office and we can help you make the appropriate recommendations.  Outside laboratories will not automatically send soil test results to our office.
