Sampling instructions

1. Using a clean bucket and a shovel, collect three samples to a depth of 6 inches in random spots in the defined area*. Avoid sampling when soil is very wet.

2. Break up any clods of soil, remove rocks, stones, sticks and plant matter, and thoroughly homogenize soil together in the bucket.

3. Take out 3 cups of soil and place into plastic bag and label with a sample ID (i.e., Stevie's front yard), type of test, and order number (found in order confirmation email).

4. Purchase your test on our website and send sample to Alluvial Soil Lab, 201 E Center St, Ste 112 #3083, Anaheim, CA 92805 using any postal carrier of your choice.

Turnaround time is between 3 and 7 business days. Results will be sent via email.

*To ensure a comprehensive soil assessment in your land, it's recommended to take one composite soil sample for every 1,000 square feet of garden space. This composite sample is created by collecting smaller soil samples from different locations within the 1,000 square feet area, allowing for a representative analysis of the soil's characteristics.

**Always wear gloves, mask, or other necessary PPE while collecting samples from potentially contaminated soils.
