Sending a Soil Sample to the University of Massachusetts Soil Testing Lab
A soil test can aid in the diagnosis of plant problems and in quality plant production. To have your growing medium analyzed, take several samples of soil at root depth from several pots, or from several areas of a bed (cut flowers) and mix it together in a clean container. Take about one cup of soil mixture dried at room temperature. Put the dry soil in a sandwich size zip-type bag and close it tightly. Identify each sample on the outside of the bag for your use. Complete and attach the "Greenhouse Media Submittal Form" with the following information:
- Name, address and phone number
- Is the sample from a newly-prepared mix or from a mix where a crop is currently being grown?
- Crop being grown, and crop age or development
- Is the sample a soilless mix? If so, what is the commercial brand?
- Does the sample have field soil in it?
- What fertilizer is in use, and what is the rate and frequency of application?
- Is this a routine sample to determine nutrient status or is it for a problem diagnosis?
Send soil samples,with a check made payable to the University of Massachusetts, to:
