IMPORTANT INFORMATION REGARDING CHANGES TO PACKAGING PROTOCOLS
Beginning June 1st 2016 each individual sample needs to be double bagged prior to packaging and shipping. Packing material such as crumpled paper or bubble wrap must be placed in the box with the samples to prevent sample movement and spillage during shipping. For more details on proper packaging and shipping instructions, please visit the ‘Testing Services’ tab on our website.

For a more complete description of sampling guidelines, including how to choose representative sub-sample locations see the soil sampling protocol section of the Comprehensive Assessment of Soil Health – The Cornell Framework Manual.

Quick guide to taking a soil sample for the Cornell Soil Health Laboratory:

Identify 10 locations within the area you would like to test that are representative of the field or plot.

A – Remove surface debris.

B– Use a spade to dig a small hole about 8” deep. From the side of the hole take a vertical slice of soil 6” deep and about 2” thick. Collect the same amount of soil from all soil depths so the sample is not biased with more soil from the top compared to the bottom.

C1 and C2 – Manually remove any extra soil to ensure an even 6” x 2” slice of soil. Place into clean pail.

D At each sub-sample location collect soil hardness information with a penetrometer. Record maximum hardness from the 0-6” and the 6-18” depth on the Submission Form.
