Our Soil and Foliar Nutrient Analysis program provides critical information on levels of nutrients in soil or in foliage during plant growth. Lab reports include a time-course evaluation of nutrient concentrations for individual fields or sites over the entire growing season. The precision and accuracy of laboratory testing depends not only on quality of lab procedures but on the sample collection and handling methods used. Consult our Soil and Foliage Sampling Guidelines for best sample collection procedures:

• Soil Sample Collection Guide
• Foliage Sample Collection Guide

The Soil and Foliar Nutrient Analysis program includes:

• Free foliage and soil sample bags
• A sample pickup and delivery service across the state of Michigan
• A quick 48-hour turnaround on analytical results
• Lab reports with a graphical summary of results over time for each field or location

Several nutrient analysis panels are recommended:

FN1 Foliar Nitrate only: NO₃

FN2 Foliar Macronutrients: P, K, S

FN3 Foliar Micronutrients: Ca, Mg, Zn, Fe, Mn, Cu, B

*Request all three for a complete nutrient analysis

SN1 Basic soil panel: pH, P, K, Ca, Mg

SN2 Soil Micronutrients: S, Zn, Mg, Fe, Ca, B

SN3 Soil Chemistry: OM, CEC, Lime Req., NO₃^-

*Request all three for a complete nutrient analysis

Soil analyses are performed on volumes of 50 or more samples only.
Please call the lab at (517) 322-0250 for free sample bags.
