    Sample Collection Instruction for Residential Lawn & Garden Fertility Package

    The lab requires 300g (3/4 lb) of 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 sample submission form and include it with your sample(s).

    Ship samples to:

    • Agriculture and Food Laboratory
      95 Stone Road West
      Guelph, Ontario
      N1G 2Z4.

    The standard turn around time for this analysis is 10 business days from receipt of sample(s).  Please include a cheque for the cost of testing made payable to the University of Guelph. This testing is HST exempt.

    Please Note that due to import restrictions, soil can not be sent to Canada without import permits. An import permit can take several weeks to obtain and has a financial commitment that would be applied to testing.
