The value of testing:

  • Testing allows you to monitor soil conditions and check the effectiveness of fertilizers and soil amendments.
  • Testing gives you the ability to adjust and fine-tune your products and product applications.
  • Ability to troubleshoot specific problem areas

SOIL SAMPLING INSTRUCTIONS 
  • Equipment should be such that sampling depth can be monitored and controlled. A stainless steel sampling probe works the best.
  • Composite samples should be collected in a plastic bucket for thorough mixing. Metal buckets can contain traces of some micronutrients (particularly zinc), which can contaminate samples.
  • Soil sample bags should be either plastic or plastic-lined. These can be supplied by AgSource Harris Laboratories

SAMPLING PROCEDURES
  • Determine which areas are to be sampled. Note for future reference, this is particularly important for fairways. It is best not to mix sub-samples from different greens or fairways; sample separately.
  • Each sample should consist of a composite of many sub-samples. About 10 to 15 sub-samples are needed to supply the laboratory with enough soil for a nutrient analysis. The volume of soil needed is roughly one cup (or approximately one pound).
  • Most important, "Keep sampling depth consistent." Golf greens should be sampled to a depth of three inches. For other turf samples, three to four inches is adequate.
  • It is advisable to include the thatch layer in your sample, since it is a biological active site. Keep in mind that this residue may contain fertilizer granules not yet dissolved or other materials that will effect the nutrient levels. Therefore, wait a minimum of two weeks after an application to collect soil samples.
  • Avoid any unusual areas in your routine sampling. These should be analyzed separately. An example would be poorly drained areas.
  • Clearly mark the sample identification (example: GRN#1) on each bag and laboratory input sheet.
PAPERWORK AND SHIPPING INSTRUCTIONS
  • Laboratory input sheets will be provided to you by AgSource Harris Laboratory. Please be sure all essential information is completed.

The following is the required information: 
  • Samples Submitted By: This will be preprinted by the laboratory that contains your unique account number and specifically identifies your company.
  • Submitted For: The name and address needs to be completed for the golf course being tested.
  • Turf Type: This is expressed in broad categories: Greens, Fairways, Tee Boxes and General Turf.
  • Be sure the sample identification on the laboratory input sheet matches up with what is labeled on the soil-sample bag(s).
  • Specify the desired analytical tests package to be performed.
  • If other tests are requested (such as pesticide residues), please specify.
  • Pack samples very tightly in a strong shipping box(s). Use packing material so the bag(s) will not shift in the box. Tape the box completely and affix a preprinted shipping label.
  • If possible, collect and ship samples the same day.
