Sampling Instructions:
Your analysis is only as good as the sample sent to the lab. Do your best to get a representative sample.Sample Submission Instructions:
Ensure the right sample size is submitted; we only need approximatel 2 - 3 cups of sample. Bring the sample in an approved clean container. Avoid heating the sample as the containers can become pressurized.**There will be an additional $5.00 handling fee for overly large or improperly submitted samples.**
Appropriate sampling containers are provided by Down to Earth Labs free of charge. You can drop by to pick them up anytime during business hours.
**For the health and safety of our staff, please provide the lab with a list of ingredients in the fertilizer. Certain chemicals can react negatively and violently with some of the reagents used during testing.**
Please make sure you include a completed submission form with samples being dropped off or sent in. The form is available on the Files & Online Submissions tab at the top of this page where you can either download and print off the form or submit it online. Samples submitted without completed and signed submission forms will be placed on hold until all appropriate information has been received. Use a meaningful identification for the sample. Labeling the samples as 1,2,3 today may not make sense a month later.
