Sampling Instructions:

Your analysis is only as good as the sample sent to the lab. Take a midstream sample if the manure is liquid and do your best to get a representative sample.

Sample Submission Instructions:

Ensure the right sample size is submitted; we only require about 250 mL of liquid manure in a 500 mL container and 2 - 3 cups of solid manure. Bring the sample in an approved, clean container. Samples should be submitted in airtight containers with at least 1" headspace to allow for expansion. Avoid heating the sample as the containers can become pressurized. 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.

**There will be an additional $5.00 handling fee if the container the sample is submitted in is dirty or too large and the lab needs to transfer the sample to another container or clean the container.**

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.
