How to Submit Soil Samples



There are two ways to submit soil samples:


1. Using your own shipping box and zip-top bags.  This method gives you more flexibility in the number of samples you can submit. It also provides a larger choice of different testing options. See sections below on how to use this method.


2. Using our sample submittal kits.  Many people prefer the convenience of a prepaid kit. These kits supply everything needed to submit soil samples, including a prepaid mailer, sample bags, instructions and submission form. Simply collect your samples and drop the mailer in your mailbox.

"We have a professional company right in our midst, Simply Soil Testing, and I have been very pleased with the results of their simple, easy to understand report that they provided on our soil samples. Our pH and nutrient problems were identified, which helped me to improve our garden soil and grow better fruits and vegetables."

Sampling Guidelines


collecting soil samples

One of the keys to getting accurate test results is proper sampling. Soil composition can vary from one spot to another in areas that look uniform. This may be due to uneven application of ferilizer in previous years, or simply due to natural variations. Make sure that your samples are representative of your yard, garden or field. To do this, take at least 5 samples from the area to be tested and mix them to form a composite. If your garden or field has areas with different soil texture, color or fertilization history, they should be sampled separately.


1. Scrape off surface residue/litter.


2. Sample from the soil surface to the depth of tillage - usually 6-8 inches for cultivated crops and 3 inches for turf.


3. Take a minimum of 5 samples and combine them in a clean container. One common sampling method is to sample in a "W" pattern, with a sample at each point. Mix the soil thoroughly.


4. Place about 1 cup in a plastic bag (such as a zip-top sandwich bad) or other container. Mark the bag with a sample description or ID.


Mailing Tips


You may consider using flat-rate mailers from the post office. The small box will hold about 4 one-cup soil samples, and costs $6.10 to ship using priority mail. The medium box will hold about 25 samples, and costs $11.95 to send.


For local customers, there is a drop box by the side door.
