Farm/Field and Commercial Horticulture Crops

Fields from above.

These tests are intended for land being used to grow agronomic and horticultural crops. Reports for soil samples submitted with the Farm/Field and Commercial Horticulture Soil Analysis Request Sheet will include crop-specific fertilizer recommendations. 

Here is a video showing how to collect samples:

How to Submit Samples for Analysis

  1. Follow instructions in the video above for collecting field samples. 
  2. Download, print and fill out the Farm/Field and Commercial Horticulture Soil Analysis Request Sheet (.pdf).  Include your email address if you prefer to receive the results via email.
  3. Make sure each sample contains about 2-3 cups of soil.
  4. Place each sample in a secure container such as a clean tupperware or sealable plastic bag. Label the container with a sample name/number that matches what you put on the request sheet.

Tests Offered

Fertilizer recommendations for optimum yield are based on laboratory results, soil characteristics, past crop history, and crop nutrient requirements. 

 

We have the ability to analyze Basal Stalk Nitrate for corn through the Research Analytical Laboratory (RAL). Learn more about Basal Stalk Nitrate testing.

 

Prices effective January 2024. Note that prices are subject to change.
