Define the areas, individuals or species that you want to assess
for mycorrhiza formation. Roots can be excavated with a small soil
corer (for putting greens and tee boxes) or a small shovel. Only
a small volume of root-containing soil is needed (half the volume
of a golf ball), but the roots need to be terminal feeder roots.
Place soil + root samples in an unsealed plastic bag to prevent
rotting or drying during shipping. Label samples individually and
indicate your goals for the assessment. Mycorrhizal colonization
can be very localized; several small samples will enable you to
identify areas where inoculum is needed or test inoculum performance
better than a single, large sample.
Soil or Inoculum
Define area (green, tee-box or fairway) to be assessed for spore
numbers. Place about a cup of soil (250 ml) in an unsealed plastic
bag to prevent anaerobic conditions. Label your samples individually
and indicate your goals for the assessment.
If you want spore counts for a particular commercial inoculum, send
us at least a cup of the inoculum (250 ml) in a sealed bag and properly
processing form in PDF format is provided here for your convinience
Call to let us know that you are sending samples and send them
promptly after collection. We will be waiting for them!
