Sample Collection Instruction for Residential Lawn & Garden Fertility Package

The lab requires approx. 300g (3/4 lb) of soil per sample collected from the top 15 cm (6 inches) of soil. Sample(s) can be put into a new, unused sandwich sized plastic bag. Please place the bags into a box for shipping to avoid splitting in transit. 

Please complete a General Sample Submission Form and include it with your sample(s).

Ship samples to:

          Agriculture and Food Laboratory
          95 Stone Road West
          Guelph, Ontario

The turn around time for this analysis is approximately 15 business days from receipt of sample(s) at the lab.  Please include a cheque for the cost of testing made payable to the University of Guelph. This testing is HST exempt.
