General Information:
- ASSUME PAYMENT MUST BE INCLUDED WITH SAMPLES.
- Organic matter (OM) is an important soil property to track, but it is not offered in some basic packages. Producers are advised to request OM even if they choose a lab that charges an additional fee for the information.
- Soil texture analysis is not offered by many labs in their basic packages. If labs do offer the analysis for a separate fee, it is often very expensive. Soil texture of the dominant map unit in a field can be obtained from Web Soil Survey.
- Soil sampling depth should be 8 inches. See Soil Sampling Procedures for more information.
- There is no need to request recommendations from the soil test labs.
- Most labs have order forms and price lists on their website.
- A new soil characteristic called the Degree of Phosphorus Saturation or DPS will be required on fields where phosphorus-bearing nutrient sources are intended and soil test phosphorus is equal to, or greater than, 150 FIV. Some labs already provide DPS as part of their basic packages while others do not. Consult the right column of the table below for information on acquiring DPS or the necessary information for calculating it.
