It All Begins With a Sample.
Soil testing is an integral part of managing soils for crop production, lawn care or even wild life food plots. Determining whether interventions are needed to improve soil fertility or alter pH is best done with a soil test. However, a soil test is only as good as a soil sample. So, before you take a sample, take a moment to review procedures outlined in the adjoining pages.
Soil samples should represent the general soil conditions of the field. An acre of soil to a 6-inch depth in a typical agricultural field weighs about 1,000 tons, yet less than 1 ounce of soil is used for each test in the laboratory. Therefore, it is very important that the soil sample is characteristic of the entire field. Learn more by following the recommended procedures.
In Wisconsin, a soil testing laboratory must be certified by the Wisconsin Department of Agriculture, Trade, and Consumer Protections (WDATCP) if results are to be used in nutrient management planning or related to any government cost sharing program. A certified testing laboratory must perform soil testing using analytical procedures as outlined by the University of Wisconsin.
Below is a listing of the soil test and approved analytical procedure used by Dairyland Laboratories, Inc.
- Soil pH
- Buffer pH
- Phosphorus (P)
- LOI Organic Matter (OM)
