Diagnostic Soil Testing

Most golf course superintendents and sports turf managers know the chemical status of their soils. But do you know the physical properties? No doubt the physical properties of a soil or sand based mix will influence the performance of the turf. We offer full physical testing on undisturbed soil cores that you submit. This testing offers an accurate picture of the soil physical properties, as they actually exist in the green or sports field. Some common uses of this testing include:

1. Where greens or sports fields are not performing to expectations, we can determine if the problem is physical. In the case of new fields or greens, we can tell if they were built to specification, or if the problem is due to maintenance during grow-in.
2. Where a superintendent or greens committee knows that the physical condition of the green is poor and needs to be replaced, we may be able to provide documentation that this is indeed the case. We rely on our extensive soils and turfgrass experience to offer you with all your options.
3. Are you considering regrassing your greens, or do you need to replace the entire green. A physical test on undisturbed cores can provide you with the information to make the right decision.

It is very important that we receive good samples. Please read the sampling instructions carefully. Failure to provide us with the good samples may require your resubmission of the samples and delay getting results back to you.

Important Note: For each green being tested, please take four (4) samples!

Step 1: Cut 2” diameter PVC pipe into sections. The pipe must be 2” diameter to fit our equipment properly. Sections should be long enough to reach through the soil profile.

Step 2: Bevel the edge on one end to provide a sharp surface to cut into the green.

Step 3: Drill two holes opposite each other at the end opposite the beveled edge. A metal rod can be inserted through these holes to provide handles for pulling the core out of the green,

Step 4: Pound the beveled edge of the PVC pipe into the green far enough to include the entire soil profile; if there is a gravel and/or choker layer, it is desirable to go down deep enough to

include this layer in the profile.

Step 5: Pull the core out. Pack space at either end with newspaper to prevent shifting of the profile. Securely tape both ends with duct tape. Pack taped cores securely for shipping.
