1. Submitted for: This is generally the name of the grower for whom the sample is submitted. This may also be the name of the farm manager, consultant etc. Some customers prefer to use a client number instead of a grower name.

2. Submitted by: The name of the firm or individual who has submitted the sample to the laboratory for analysis. This individual or firm is billed for the analysis conducted on the soil sample.

3. Field: Identifies where the sample was collected. The name of the field can be made up of any combination of letters and numbers (15 character limit).

4. Sample: Identifies each sample, when there is more than one sample collected from each field (10 character limit).

5. County: Identifies the county in which the sample was taken (15 character limit).

6. Township: Identifies the township in which the sample was taken (15 character limit).

7. Section: Identifies the section of the township in which the sample was collected (5 character limit).

8. Quarter: Identifies the quarter of the section in which the sample was collected (2 character limit).

9. Acres: Identifies the acres represented by the soil sample submitted. (5 character limit).

10. Previous Crop: Identifies the crop which was grown just prior to soil sampling. This information may be used to adjust nitrogen guidelines when a legume is the previous crop.

11. Reference Number: This is the number printed on the sample information sheet sent to the laboratory with the sample. Each sample has a distinct reference number and is tracked through the laboratory by this number. When calling the laboratory for information on a sample, the caller must know the reference number before information will be provided on any sample.

12. Laboratory Number: This number is assigned to each sample for internal use and quality control in the laboratory.

13. Box Number: This is the temporary storage box for this sample at the laboratory.

14. Date Sampled: Indicates the date the sample was collected.

15. Date Received: Indicates the date the sample arrived at the laboratory.

16. Date Reported: Indicates the date the soil sample report was printed.

Laboratory Analysis on Various Soil Sample Depths

The laboratory tests that are routinely run on each sample depth are shown in the figure below. The top-soil (0-6")is analyzed for all nutrients and physical soil properties. The sub-soil (6-24") is analyzed for mobile nutrients such as nitrate-nitrogen, sulfur, chloride and soluble salts. Deep sub-soil samples (24-48" or deeper) are also analyzed for nitrate-nitrogen.

A separate top-soil (0-6") sample is required for analysis of non-mobile nutrients such as phosphorus and potassium. If 0-12" or 0-24" samples are submitted for phosphorus and potassium analysis the resulting laboratory data and fertilizer guidelines may not be correct. The subsoil contains little phosphorus in most areas. The example below indicates how sampling depth will affect phosphorus soil test levels.

EXAMPLES
Sample Depth	P soil test (ppm)
0"-6"	15 ppm
0"-12"	9 ppm
0"-15"	6 ppm
