Soil and Forage Testing for Farmers
Soil Testing: You can pull samples any time after the ground is thawed to 9 inches. Remember, 2 Cups of soil pulled from 10 random pulls on a uniform 10-5 acre field is a reasonable sample for analysis. Note that you now send samples to the Madison lab for analysis. See: University of Wisconsin Soil Test Lab website at https://uwlab.soils.wisc.edu/ for more information. Here is a PDF of the submission form: https://uwlab.soils.wisc.edu/wp-content/uploads/sites/17/2022/02/RFS-1-22.pdf.
Forage Testing: Pull 10 – 20 cores from one hay lot. Is it time to take a soil test? It is recommended that your agricultural fields have their soils sampled and tested once every 3-4 years. Soil testing is the basis for sound hayland and cropland management on your farm. For relatively little cost, you can achieve substantial information. Knowing your soil’s fertility can protect you from over or under fertilizing and saving money for your operation. Plan to pull samples for this year’s crop after first cut. Are you at the appropriate Relative Feed Quality this year? (Dairy-150, Beef- 120-135) Note: Organic Valley producers are in for a premium if they can produce exclusively on grass. KNOW your RFQ so you can reach that market.
